Description

Parameter deleting method and device

Technical Field

The embodiment of the specification relates to the technical field of computers, in particular to a method and a device for deleting parameters and a method and a device for deleting or changing elements in a knowledge graph.

Background

Currently, when a configurator wants to delete a certain parameter with a called condition, the system usually only prompts the configurator that the parameter cannot be deleted due to the called condition. For example, a sample inquiry sentence corresponding to a user intention is generally configured in the conversation robot, the sentence can be used for comparing with a user dialogue on one hand to identify the user intention corresponding to the user dialogue, and on the other hand, parameters can be called in the sentence to acquire parameter information corresponding to the parameters in the user dialogue, so that the conversation robot can further determine reply content for the user dialogue by combining the user intention and the parameter information corresponding to the user dialogue, and when a configurator needs to delete the parameters called in the sample inquiry sentence in the background, the system prompts that the parameters cannot be deleted due to being called.

Therefore, a reasonable method is needed to be provided, so that a configurator can quickly adjust the content related to parameter call to release the call relationship, and further delete the parameters.

On the other hand, in a scenario involving element editing, since a plurality of elements are not always completely independent, that is, one element may have an association relationship with another element, when deletion or modification of one element is required, other elements associated with the element may be affected. For example, in the construction of a knowledge graph, including the construction and editing of types, attributes and entities, when a type is deleted or changed, the attributes and entities associated therewith are generally affected.

However, when deleting or changing an element in the conventional scheme, the user is usually informed of the careful deletion or change operation only through a sentence. Accordingly, there is a need to provide a reasonable way to provide a user with a range of impact to which an element is to be deleted or changed to assist the user in determining whether to delete or change the element.

Detailed Description

Various embodiments disclosed in this specification are described below with reference to the accompanying drawings.

The parameter deleting method disclosed in the embodiment of the present specification may be applied to a scenario in which some or some parameters in which a called situation exists are to be deleted or deleted in batch. Next, referring first to fig. 1, an application scenario of the method will be described according to a specific example.

FIG. 1 illustrates a user intent configuration interface schematic according to one example. As shown in fig. 1, the target user intention configured in the interface is "buying a train ticket", and the sample query sentence configured for identifying the target user intention includes: "I want to buy tickets from $ { start time } to $ { end time }," $ { start time } also do, i want to buy tickets from $ { departure place } to $ { destination }, etc., where "$ { }" is a call symbol and "start time" is a called parameter name. The target user intention configured based on the interface shown in fig. 1 may be plural, for example, buying a train ticket, buying a traffic package, or the like, and the configured content data may be used for a conversation robot, and specifically, the conversation robot may receive a user conversation transmitted by a user, for example, "the train ticket is also the same in tomorrow evening", and then calculate the similarity of the user conversation to a plurality of sample query sentences corresponding to the plural target user intentions, assuming that the sample query sentence corresponding to the highest value in the determined similarity is: the train ticket of "$ { start time } also has the same" from which it can be determined that the user intends to buy the train ticket ", and the dialog element is identified from the user dialog by the call parameter $ { start time } therein, that is," tomorrow evening ", and the train ticket service component is called again to determine the reply content for the user dialog, for example, the determined reply content may be" two trains with 21:00 and 22:00 departure in the evening ".

Based on the interface shown in fig. 1, when one or more of parameters set therein, such as start time, end time, departure place or destination, etc., need to be deleted, the method provided by the embodiment of the present specification may be adopted to retrieve, from among a plurality of sample query sentences corresponding to "buy train tickets" intended by the user, a sample query sentence calling parameters to be deleted, such as start time, e.g. "i want to buy train tickets" of $ { start time } to $ { end time }, and "$ { start time }, and then present the retrieved sample query sentences to a configurator, for example, the presentation interface may be as shown in fig. 2, to prompt further operations required to be performed by the configurator to delete parameters, e.g." call case in clear sentence "and" delete confirmation "shown in fig. 2. Next, specific implementation steps of the method will be described.

Fig. 3 shows a flowchart of a method for deleting parameters, according to one embodiment, the method execution subject may be a device with processing capabilities: a server or system or device. As shown in fig. 3, the method flow includes the steps of: step S310, responding to a deleting instruction of parameter information of dialogue parameters, acquiring a dialogue statement set established for identifying user intention of user dialogue; step S320, retrieving at least one dialogue sentence with dialogue parameters from the dialogue sentence set; step S330, at least one dialogue sentence is presented in the editable dialogue box to prompt further operations to be performed to delete the dialogue parameters.

Further, in one embodiment, in step S340, in response to an editing instruction for at least one dialogue sentence in the dialogue box, acquiring at least one edited dialogue sentence, and detecting whether a dialogue parameter is invoked in the at least one edited dialogue sentence; step S350, under the condition that the dialogue parameters are not called in at least one edited dialogue statement, displaying first prompt information to prompt whether to confirm the current editing; step S360, in response to the editing confirmation instruction of the current editing, displaying second prompting information to prompt whether to confirm to delete the parameter information; step S370, in response to the deletion confirmation instruction of the parameter information, updating the at least one dialogue sentence in the dialogue sentence set to the edited at least one dialogue sentence, and deleting the parameter information.

First, in step S310, a dialog sentence set established for identifying a user intention of a user dialog is acquired in response to a deletion instruction of parameter information of dialog parameters.

In one embodiment, the dialog parameters for which the delete instruction is directed may be one or more, that is, the configurator may delete a single dialog parameter or may delete multiple dialog parameters in bulk.

In one embodiment, the operation corresponding to the delete instruction may be a click operation on a delete marker corresponding to the parameter information line, for example, a click operation on a garbage can-like delete symbol displayed on the right side after selecting the parameter information line corresponding to "start time" in the interface shown in fig. 1.

In one embodiment, the dialog parameters are set to identify dialog elements in a user dialog. In a specific embodiment, the user session comprises a user session received by a customer service person or a customer service robot from a user. In a specific embodiment, specific information, i.e. dialog elements, correspondingly included in the user dialog may be obtained by invoking dialog parameters. For example, a dialogue sentence "$ { start time }" including a dialogue parameter "$ { start time }" may be set, and a dialogue from the user "is there a ticket at 8 pm today? "dialog element identified in" 8 pm today ".

In one embodiment, the parameter information for the dialog parameter includes a parameter name for the dialog parameter, e.g., a "start time". In one embodiment, the parameter information further includes entity information corresponding to the dialogue parameter, for example, entity information corresponding to "start time" and "end time" is "time", and entity information corresponding to "departure place and" destination "is" place ". In one embodiment, the parameter information further includes tag information corresponding to the dialog parameters, for example, the tags corresponding to "start time" may include text tags describing time such as "tomorrow morning", "tomorrow evening", "next monday", and so forth. In one embodiment, the parameter information further includes numerical information corresponding to the dialog parameter, such as a numerical format of "xx" points, "xx", and the like. In one embodiment, the parameter information further includes question session information corresponding to the dialogue parameters, for when the dialogue sentence fails to identify a corresponding dialogue element from the user dialogue by invoking the dialogue parameters, then the user may be asked for the question accordingly to acquire the dialogue element, e.g., when "start time" is not acquired, "please ask the user for train departure time is? ".

In one embodiment, a set of dialogue sentences is used to identify user intent of a user dialogue, including a plurality of dialogue sentences that are used to compare, match, and query the dialogue with the user dialogue as sample query sentences to determine intent of the user dialogue. At least one dialogue parameter may be called or not in each dialogue sentence, and for any two dialogue sentences which call dialogue parameters, the called dialogue parameters may be completely the same, or partially the same, or completely different.

The purpose of the dialogue statement calling dialogue parameters is to identify dialogue elements in the user dialogue, and further determine reply content for the user dialogue according to the identified dialogue elements. Further, in one embodiment, the dialog sentence may call a dialog parameter by calling a symbol and a parameter name of the dialog parameter, e.g., the call may be in the form of $ { XXX }, where $ { } is a call symbol and XXX is a parameter name.

According to one example, based on the configuration page of the user intention "buy train ticket" shown in fig. 1, in response to a deletion operation of a parameter information line in which a dialogue parameter "start time" is performed, a dialogue sentence set corresponding to the user intention is acquired, the dialogue sentence set including a plurality of dialogue sentences: "I want to buy tickets from $ { start time } to $ { end time }", "$ { start time } also do $", "I want to buy tickets from $ { departure place } to $ { destination }, etc.

In the above, a set of dialogue sentences established for recognizing the user intention of the user dialogue can be acquired. Next, at step S320, at least one dialogue sentence having dialogue parameters invoked is retrieved from the dialogue sentence set.

In one embodiment, the dialogue parameter to be deleted is one, and accordingly, at least one dialogue sentence having the dialogue parameter invoked therein may be retrieved from the dialogue sentence set. In one example, the dialogue parameter to be deleted is "start time", and then the dialogue sentence including $ { start time } can be retrieved from the dialogue sentence set.

In another embodiment, the number of dialogue parameters to be deleted is plural, and accordingly, at least one dialogue sentence calling any one of the plural dialogue parameters can be retrieved from the dialogue sentence set. In one example, the dialogue parameters to be deleted are "start time" and "end time", and then dialogue sentences including $ { start time } or $ { end time } can be retrieved from the dialogue sentence set.

Then, in step S330, the at least one dialogue sentence is presented in an editable dialogue box to prompt further operations to be performed to delete the dialogue parameters.

Therefore, the configurator can edit at least one dialogue sentence according to the further operation required by the prompted dialogue parameter deletion, so as to release the calling relation between the dialogue sentence and the dialogue parameter. According to one example, as shown in FIG. 2, two dialogue statements called with the dialogue parameter "start time" may be presented in an editable dialogue box, and further actions that prompt deletion of the dialogue parameter need to be performed include "call in clear statement" and "delete confirm".

In one embodiment, the step may further include: in the dialog box, dialog parameters and/or call signs for dialog parameters are highlighted. In one example, highlighting may include bolding, enlarging, highlighting with a different color than other text in the page, and so forth. For example, in the dialog box shown in fig. 2, "$ { start time }" is bolded.

After the dialogue sentence with the dialogue parameter is shown in the editable dialogue box, in step S340, in response to the edit instruction for at least one dialogue sentence in the dialogue box, at least one edited dialogue sentence is obtained, and whether the dialogue parameter is called in the at least one edited dialogue sentence is detected.

In one embodiment, detecting whether a dialog parameter is invoked in the edited at least one dialog sentence includes detecting whether a call symbol for the dialog parameter is included therein, that is, detecting whether "$ { XXX }" exists, where XXX is the parameter name for the dialog parameter. Further, in one example, for "$ { XXX }" included in the dialogue sentence, when it is detected that it is edited as "XXX", for example, it is determined that the call symbol for XXX is not included in the dialogue sentence, as is also the case with "$ { start time }" for the train ticket. In another example, when "$ { XXX }" is edited to "{ XXX }", or "$xxx", etc. that does not include the complete call symbol, for example, the "$ { start time } train ticket also has the" $ { start time "$x" edited, it may be determined that the call symbol for XXX is not included in the dialogue sentence. In yet another example, when "$ { XXX }" is deleted, for example, it may be determined that "$ { start time } train ticket also has been edited as" train ticket also has "that call symbol for XXX is not included in the dialogue sentence.

Then, in step S350, in the case that it is detected that the dialog parameter is not invoked in at least one dialog sentence after editing, a first prompt message is displayed to prompt whether to confirm the current editing.

It should be noted that, the "first" of the "first prompt information" and the "second" and "third" of the "second prompt information" and the "third" of the "third prompt information" mentioned below are for distinguishing the prompt information generated under different conditions, and do not have other limitation.

According to one example, when the dialog parameters are not invoked in the edited at least one dialog sentence, the corresponding interface may be as shown in fig. 4. Further, in one example, displaying the first hint information may include: the "next" button shown in fig. 4, from the non-clickable state to the clickable state, may specifically implement a prompt by a color conversion, for example, from gray to blue. Thus, the configurator can confirm the current editing operation by clicking the "next" button. In another example, displaying the first hint information may include: the first prompt information is displayed in a popup window mode, for example, the content of the prompt information can be: "does it confirm the modification made to the current content? And provides the keys of yes and no for the configurator to select.

When the call relation between the dialogue statement and the dialogue parameter in the dialogue box is detected to be relieved, the configurator is prompted to confirm whether the current editing operation is performed. Next, in step S360, in response to the edit confirmation instruction of the current edit, second prompting information is displayed to prompt whether deletion of the parameter information is confirmed.

According to one example, displaying the second prompt may include prompting the configurator to currently enter "(2) delete confirm" step, deleting the current parameter by clicking on the confirm button, or clicking on "previous" to return to the edit page for the dialogue statement, or clicking on "cancel", canceling the delete operation, as shown in fig. 5.

In step S370, at least one dialogue sentence in the dialogue sentence set is updated to at least one edited dialogue sentence in response to the deletion confirmation instruction for the parameter information, and the parameter information is deleted.

In one embodiment, according to the editing operation of the configurator on each dialogue sentence in the dialogue box, the corresponding dialogue sentence stored in the system is updated, and the parameter information stored in the system is deleted. Thus, the deletion of the parameter information is completed.

After step S370, the method may further include: and displaying feedback information to inform configuration personnel that the parameter information is successfully deleted, for example, the content of the feedback information can be: the deletion was successful. Further, in one example, the user intent interface after deleting the parameter information may be as shown in FIG. 6.

As can be seen from the foregoing, in the method for deleting parameters provided in the embodiments of the present disclosure, in response to a deletion instruction for parameter information of a dialog parameter associated with a user intention, a dialog sentence set corresponding to the user intention is obtained, at least one dialog sentence calling the dialog parameter is retrieved from the dialog sentence set, and is displayed to a configurator in a manner of being able to edit the dialog box, so that the configurator can edit the dialog sentence directly in the dialog box to release the call of the dialog parameter by the dialog sentence, and then after the dialog box is detected that the dialog parameter is not called, prompt the configurator to perform deletion confirmation, and complete deletion of the parameter information according to the deletion confirmation instruction. Therefore, the configuration personnel can analyze and confirm whether the parameter information needs to be deleted according to at least one displayed dialogue statement, and can quickly and conveniently complete the deletion of the parameter information under the condition of deciding to delete.

According to another embodiment, the present disclosure further provides another method for deleting a parameter. Fig. 7 shows a flowchart of a method for deleting parameters according to another embodiment, where the method may be performed by a device with processing capabilities: a server or system or device. As shown in fig. 7, the method flow includes the steps of: step S710, responding to the deleting instruction of parameter information of dialogue parameters, acquiring a dialogue statement set established for identifying user intention of user dialogue; step S720, retrieving at least one dialogue sentence with dialogue parameters from the dialogue sentence set; step S730, displaying at least one dialogue sentence in the editable dialogue box to prompt further operations required to delete the dialogue parameters; step S740, responding to the editing instruction of at least one dialogue sentence in the dialogue box, obtaining at least one edited dialogue sentence, and detecting whether dialogue parameters are called in the at least one edited dialogue sentence; step S750, under the condition that the dialogue parameters are not called in at least one edited dialogue statement, displaying second prompt information to prompt whether to confirm to delete the parameter information; step S760, in response to the deletion confirmation instruction for the parameter information, updating the at least one dialogue sentence in the dialogue sentence set to the edited at least one dialogue sentence, and deleting the parameter information.

It should be noted that, for the descriptions of steps S710, S720, S730, S740 and S760, reference may be made to the descriptions of steps S310, S320, S330, S340 and S370, respectively, which are not described herein.

In addition, the embodiment shown in fig. 7 is mainly different from the embodiment shown in fig. 3 in step S750. Specifically, in step S750, if it is detected that the dialog parameter is not invoked in at least one edited dialog sentence, it may be directly prompted whether the configurator confirms that the parameter information is deleted, without prompting the configurator to confirm the current editing first, and prompting the configurator to confirm whether to delete the parameter information after the configurator confirms the current editing. In this way, the flow of deleting the parameter information can be further shortened.

According to an embodiment of still another aspect, the present disclosure further provides a method for deleting another parameter. Fig. 8 shows a flowchart of a method for deleting parameters according to another embodiment, where the method may be performed by a device with processing capabilities: a server or system or device. As shown in fig. 8, the method flow includes the steps of: step S810, responding to a deleting instruction of parameter information of dialogue parameters, acquiring a dialogue statement set established for identifying user intention of a user dialogue; step S820, retrieving at least one dialogue sentence with dialogue parameters from the dialogue sentence set; in step S830, at least one dialogue sentence is displayed in the editable dialogue box to prompt that the parameter information cannot be deleted.

It should be noted that, for the description of step S810 and step S820, reference may be made to the foregoing descriptions of step S310 and step S320, which are not repeated herein.

At step S830, at least one dialogue sentence is presented in the dialogue box to indicate that the parameter information cannot be deleted.

According to one example, the configuration interface is shown in FIG. 9. Therefore, the method can inform the configurator that the dialogue parameters which are required to be deleted cannot be deleted because the dialogue parameters are called in the dialogue sentences, and inform the configurator that the dialogue parameters are specifically called by the dialogue sentences, and prompt the configurator that the call relation between the configurator and the dialogue sentences needs to be released when the configurator deletes the dialogue parameters, so that the configurator can further determine whether to delete the dialogue parameters according to the call relation. If the configurator still decides to delete the dialogue parameters, the configurator can search at least one corresponding dialogue sentence in the editing column of the dialogue sentence according to at least one dialogue sentence displayed in the dialogue box so as to release the calling relation of the dialogue parameters, and then try to delete the dialogue parameters again in the parameter information editing column after releasing the calling relation.

According to another embodiment, a device for deleting parameters is also provided. Fig. 10 shows a deletion apparatus of parameters including dialog parameters set for identifying dialog elements in a user dialog, according to an embodiment. As shown in fig. 10, the apparatus 1000 includes:

A first acquisition unit 1010 for acquiring a dialogue sentence set established for identifying a user intention of the user dialogue in response to a deletion instruction of parameter information of the dialogue parameter;

The embodiment of the specification also discloses a method for deleting or changing the elements in the knowledge graph, wherein the elements in the knowledge graph comprise types, attributes and entities, and the method mainly aims at the types and the attributes. In the following, the inventive concept of the method will be described first.

With the development of the internet, network data content presents an explosively growing situation. Because the internet content has the characteristics of large scale, heterogeneous multiple, loose organization structure and the like, how people can effectively acquire knowledge and information from the internet becomes a great challenge, and the knowledge graph lays a foundation for the organization and intelligent application of knowledge information in the internet era by virtue of the strong semantic processing capability and the open organization capability.

Generally, elements in a knowledge graph include entities (entities), types (classes), and properties (properties). Wherein, the entities are the most basic elements for constructing the knowledge graph, each entity represents a thing or concept, and is an abstraction or description of objective things, such as "Yao Ming", "alembia". A type (which may be referred to as a "class") is an abstraction of a collection of entities having the same trait or attribute, e.g., "persona" is a type, and "Yao Ming", "Li An" are entities belonging to the type "persona". The attribute may represent a feature possessed by a class or an entity, and may be used to describe a relationship between classes and entities, and between entities and entities, for example, a relationship between "movie→director→persona", or "sleeping tie→director→ Li An", whereby "movie" and "sleeping tie" have "director" attributes.

As can be seen from the above, the elements in the knowledge graph, i.e. the types, attributes and entities, have an association relationship, so that when deleting/modifying one element, other elements are affected, and the knowledge graph generally includes a larger data amount, so that the deleting/modifying operation will have a larger scope of influence. For example, when a type is deleted/changed, the properties it has, and the entity it maps to will be affected. For another example, when a deletion/modification is made to an attribute, the entity with that attribute will be affected. In addition, when deleting an entity, only information related to the entity, such as the entity itself, the attribute of the entity, or the corresponding attribute value, is usually deleted, and the influence scope is relatively small, so the method disclosed in this specification is mainly aimed at deleting/modifying types and attributes. However, in the conventional scheme, when deleting the type in the knowledge graph, only a sentence is usually used, for example, "whether it is determined to delete the item? ", to alert the user that the operation is to be performed carefully.

Based on this, the embodiment of the present disclosure provides a deletion/modification method, which determines a corresponding influence range in response to a deletion/modification instruction for an element in a knowledge graph, so that a user can determine whether to perform a deletion operation through sufficient information, thereby preventing a user from deleting/modifying content by mistake, which may cause unrecoverable loss or huge recovery cost loss. The application flow of the method for deleting an element in the knowledge-graph is described below in detail with reference to a specific example.

As shown in fig. 11, in response to a click deletion instruction of a user on an element in a knowledge graph, an influence range of the element is searched in the background, and the influence range is presented to the user in a secondary confirmation popup, so that the user can judge in combination with browsed information, and in the case of deciding to delete the element, input corresponding characters, such as "confirm deletion (element name)", in the secondary confirmation popup according to a prompt, and then in response to the click confirmation instruction, delete the corresponding element, and prompt the user that the deletion is successful. Next, specific implementation steps of the method are described.

Fig. 12 is a schematic diagram of a method for deleting an element in a knowledge graph, where the element of the knowledge graph includes a type, an attribute, and an entity, and the entity having the same attribute forms a type, and an execution subject of the method may be a device having processing capability according to an embodiment: a server or system or device. As shown in fig. 12, the method flow includes the steps of: step S1210, in response to a deletion instruction of a first type in the knowledge spectrogram, retrieving a first attribute set and a first entity set; in step S1220, deletion prompting information is displayed, where the information includes at least related information of the first attribute set and the first entity set, so as to prompt deletion of the influence range of the first type.

First, in step S1210, in response to a deletion instruction for a first type in the knowledge spectrogram, a first attribute set and a first entity set are retrieved, where the first attribute set is composed of attributes that the first type has, and the first entity set is composed of entities that belong to the first type.

In one embodiment, the delete instruction may correspond to a variety of modes of operation, such as clicking a delete button, entering a voice command, entering a text command, and so forth. In a specific example, the first type may be "organization" shown in fig. 13, and the delete instruction corresponds to a click operation on an icon of "delete category".

In one embodiment, retrieving the first set of attributes may include: the attributes of the first type are determined, and the determined attributes form a first set of attributes. Further, in one particular embodiment, the attributes that the first type has may include inherited attributes that the first type inherits from its parent, as well as own attributes that the first type own. In one example, assuming that the first type of "organization" does not have a parent, the corresponding first set of attributes includes only "organization" own attributes, such as board length, social credit code, and the like. In another example, assuming that a first type of "jazz" has a parent class of "music" and the attributes of "music" include "year", a first set of attributes corresponding to "jazz" may include the inherited attributes "year" and the own attributes "originating place".

In one embodiment, retrieving the first set of entities may include: determining entities belonging to a first type, and forming the determined entities into a first entity set. In one example, entities belonging to the first type of "organization" may include "WTO", "alembia", etc., and thus the first set of entities may include WTO, alembia, etc.

On the other hand, in one embodiment, the knowledge graph logically includes a model layer and a fact layer, where the model layer may include types and attributes, the fact layer includes entities, and the fact layer is mainly composed of a series of facts, which store knowledge in units of facts, e.g., facts may be expressed in triples of (entity 1, attribute, entity 2), (entity, attribute value). In addition, the classes and properties edited in the model layer will map into the entities of the fact layer, for example, "company→board length" is included in the model layer, and after mapping into the fact layer, "aleba→board length" may be correspondingly included in the fact layer. Further, in a particular embodiment, the editing of the model layer and the editing of the fact layer may be separate in two different editors, such that the type and properties may be edited in one of the editors and the entity may be edited in the other editor, it being understood that the editing of the type or property may affect the entity in the other editor.

According to a specific embodiment, the step may include: in response to a delete instruction of a first type in the model layer, a first set of attributes is retrieved at the model layer and a first set of entities is retrieved at the fact layer.

In the above, it is possible to determine the first attribute set constituted by the attributes possessed by the first type, and the first entity set constituted by the entities belonging to the first type. Next, in step S1220, a deletion hint is displayed, where the deletion hint includes at least information related to the first attribute set and the first entity set, to hint to delete the scope of influence of the first type.

In one embodiment, the first set of attributes and the related information for the first set of entities may include a number and/or names of entities in the first set of entities and a number and/or names of attributes in the first set of attributes.

In one embodiment, the first type has at least one sub-class, where each sub-class has properties that include at least its inherited properties inherited from the parent class, and may also include its own properties. According to a specific embodiment, at least one of the sub-classes may belong to the same hierarchy or may belong to different hierarchies. For the subclass in which it belongs to the next hierarchy of the first type, the inherited attribute it has is the attribute that the first type has.

Accordingly, in such a case, an embodiment of the present specification may further include the steps of: a sub-class set of at least one sub-class is determined, and a second set of attributes of each sub-class in the sub-class set and a second set of entities belonging to each sub-class are determined. From the foregoing, it will be appreciated that the subclass of the first type inherits the attributes of the first type, and thus, the second set of attributes will contain all of the attributes in the first set of attributes. In addition, entities belonging to the respective subclasses necessarily also belong to the parent class, i.e. the first type, and thus the second set of entities is typically a subset of the first set of entities.

Further, in a specific example, the first type "organization structure" has the subclass "company" having the attribute including the inherited attribute "board length" and the own attribute "time of establishment", the entity belonging to the "company" includes "aleba" and the like, and thus the second attribute set includes "board length", "time of establishment" and the like, and the second entity set includes "aleba".

Accordingly, in one embodiment, the deletion hint information displayed in step S1220 may further include a first type of sub-class set, a second attribute set formed by attributes of each sub-class, and a second entity set formed by entities belonging to each sub-class.

According to a specific embodiment, it is assumed that the first type is an "organization", its subclasses are "company", the properties of the "organization" include "board length", "the properties of the company" itself include "time of establishment", the entity belonging to the "company" is "aleb", the entities belonging to the "organization" are "WTO" and "aleb". Accordingly, as shown in fig. 14, the deletion hint information may include the contents: "delete class will affect 2 classes, 2 attributes and 2 entities" and the names of the classes, attributes and entities.

On the other hand, in one embodiment, displaying the deletion hint information may include: the first type and the sub-class set consisting of its sub-classes are presented in the form of a tree structure, wherein the first type corresponds to a parent node in the tree structure and each sub-class in the sub-class set corresponds to a child node in the tree structure. According to a specific example, a type tree is shown in fig. 15, wherein the first type is music, and the subclasses in the subclass set include classical music, popular music, mid-century music, country music, and the like.

Further, in an embodiment, displaying the prompt information may further include: the first type and the subset are presented in a clickable tree structure. According to a particular embodiment, each attribute in the first set of attributes and each entity in the first set of entities may be presented in response to a view instruction for the first type of information. In one example, as shown in fig. 16, in response to a click operation on "organization", the attributes "board length" and entities "WTO" and "aleb" may be presented. According to another specific embodiment, the attribute of each subclass and the entity belonging to each subclass may be presented in response to an information viewing instruction for each subclass in the set of subclasses. In one example, as shown in fig. 17, in response to a click operation on "company", its own attribute "time of establishment" and inherited attribute "board length" may be presented, as well as an entity "aleba".

By displaying the related information of the attribute set and the entity set in the deletion prompting information, the influence range of the first type is prompted to be deleted, so that a user can judge whether to perform the deletion operation according to sufficient information.

Further, according to an embodiment, after step S1220, it may further include: and deleting the first type, the first set of attributes and the first set of entities in response to a deletion confirmation instruction for the first type. In another embodiment, the first type, the subset, the second set of attributes, and the first set of entities may be deleted. Further, according to a specific embodiment, the delete confirmation instruction may correspond to a click operation of any of the "confirm" buttons of fig. 14-17. In another specific embodiment, the deletion prompting information may further include prompting content of the operation mode for deletion confirmation, and accordingly, when the user operation is detected to be matched with the operation mode of prompting, the retrieved information of the attribute, the entity and the like related to the first type is deleted. In one example, shown in fig. 18: when the "delete" class is input below, correspondingly, when it is detected that the character in the input box matches with the preset rule, for example, the character content is "delete organization structure class", the confirm button may be controlled to be changed from the click invalid state to the click valid state, and then in response to the click operation on the confirm button, the 2 classes, 2 attributes and 2 entities mentioned in the prompt information are deleted.

In summary, in the method for deleting the type in the knowledge graph disclosed in the embodiments of the present disclosure, a corresponding influence range is determined in response to a deletion instruction for the type in the knowledge graph, so that a user can determine whether to perform a deletion operation through sufficient information, thereby preventing the user from deleting the content by mistake and causing unrecoverable loss or huge recovery cost.

The method for deleting the types in the knowledge graph is introduced, and then the method for deleting the attributes in the knowledge graph is introduced. Fig. 19 is a schematic diagram showing a method for deleting an element in a knowledge graph according to another embodiment, where the element of the knowledge graph includes a type, an attribute, and an entity, and the entity having the same attribute forms one type, and an execution subject of the method may be a device having processing capability: a server or system or device. As shown in fig. 19, the method flow includes the steps of: step S1910, in response to the deletion instruction of the first attribute in the knowledge graph, retrieving an entity set, wherein the entity set is composed of entities with the first attribute; step S1920 displays deletion prompt information, where the information includes related information of the entity set to prompt deletion of the influence range of the first attribute.

First, in step S1910, in response to a deletion instruction of a first attribute in the knowledge-graph, an entity set composed of entities having the first attribute is retrieved.

In one embodiment, the delete instruction may correspond to a variety of modes of operation, such as clicking a delete button, entering a voice command, entering a text command, and so forth. In a specific embodiment, assuming that the first attribute is "board length," deletion of that attribute may be accomplished by a voice control instruction "delete board length.

In one embodiment, retrieving the set of entities may include: an entity having a first attribute is determined and the determined entity is formed into a set of entities. In one example, it may be determined that entities having an "age" attribute include "Li An" and "Yao Ming" and the like, and accordingly, the set of entities may include "Li An" and "Yao Ming" and the like.

In one embodiment, each entity in the entity set further has a first attribute value corresponding to the first attribute, and accordingly, the step may further include: a first attribute value for each entity is determined. In one example, assuming that the set of entities includes entity "Li An," it may be determined that it has a first attribute value corresponding to "age" of "64 years.

On the other hand, in one embodiment, the knowledge graph logically includes a model layer and a fact layer, and specific reference may be made to the related descriptions in the foregoing embodiments. Further, in a specific embodiment, the step may include: in response to a delete instruction for the first attribute in the model layer, the set of entities is retrieved at the fact layer.

Above, the entity set constituted by the entities having the first attribute can be determined. Next, in step S1920, deletion prompting information is displayed, where the information includes information about the entity set to prompt deletion of the influence range of the first attribute.

In one embodiment, the related information for the set of entities may include the number and/or names of the entities therein. In one embodiment, the related information may include that each entity in the set of entities has a first attribute value corresponding to the first attribute. According to a specific example, the related information may include: (Li An, age, 64 years), (Yao Ming, age, 38 years).

By displaying the related information of the entity set in the deletion prompting information, the influence range of the first attribute is prompted to be deleted, so that a user can judge whether to perform the deletion operation according to sufficient information.

Further, according to an embodiment, after step S1920, it may further include: and deleting the first attribute of each entity in the entity set in response to a deletion confirmation instruction of the first attribute. In addition, when each entity has a first attribute value corresponding to the first attribute, it is also necessary to delete the first attribute value that each entity has.

Further, in a specific embodiment, the first attribute may be deleted in the model layer, and the first attribute value that each entity in the entity set has are deleted in the fact layer.

In summary, in the method for deleting the attribute in the knowledge graph disclosed in the embodiments of the present specification, the corresponding influence range is determined in response to the instruction for deleting the attribute in the knowledge graph, so that the user can determine whether to perform the deletion operation through sufficient information, thereby preventing the user from deleting the content by mistake and causing unrecoverable loss or huge recovery cost loss.

According to an embodiment of another aspect, a method of modifying an element is also provided. FIG. 20 illustrates a schematic diagram of a method of modifying elements in a knowledge-graph, the elements of the knowledge-graph including types, attributes, and entities, the entities having the same attributes comprising one type, an execution subject of the method may be a device having processing capabilities, according to one embodiment: a server or system or device. As shown in fig. 20, the method flow includes the steps of: step S2010, in response to a modification instruction of a first type in the knowledge spectrogram, retrieving a first attribute set and a first entity set; in step S2020, a change prompting message is displayed, where the message includes at least information related to the first attribute set and the first entity set, so as to prompt for changing the influence range of the first type.

It should be noted that the main difference between the present embodiment and the embodiment shown in fig. 12 is that in the present embodiment, a change operation is performed on a type, and in fig. 12, a delete operation is performed on a type, where the displayed hint information is similar, and in addition, in response to the change confirmation operation, the type is changed, for example, an "organization structure" is changed to an "organization" instead of deleting. Based on this, the description of the present embodiment may refer to the foregoing description of the embodiment shown in fig. 12, which is not repeated herein.
