FIG. 2 schematically illustrates a flow diagram of a transformation method based on a use-case approach in accordance with an embodiment of the disclosure.

As shown in fig. 2, the method includes operations S201 to S203.

In operation S201, keywords in an operation description natural language for expressing a general flow of a business operation are extracted, wherein the keywords include at least one role keyword, at least one action keyword corresponding to each role keyword, and an operation object keyword corresponding to each action keyword.

In operation S202, a role lane diagram for expressing a business operation sub-process executed by each operator role is generated according to each keyword, wherein each role lane diagram is expressed in the form of a diagram, each role lane diagram includes role graph elements for expressing meanings of the role keywords and at least one operation graph element associated with each role graph element for expressing meanings of the action keywords, and the operation graph elements for expressing meanings of the action keywords and the operation object keywords corresponding to the action keywords.

In operation S203, all the character lane diagrams are combined according to the operation sequence of the business operation general flow to generate a general use case diagram for expressing the business operation general flow.

According to the embodiment of the disclosure, in an application scenario of the embodiment of the disclosure, a user inputs a case name to be queried through a terminal device, a server presents the case name to the user in a presentation mode (a case specification expressed in a natural language or an activity diagram expressed in a use case diagram mode) pre-stored in a system according to a user request, and after obtaining a case presentation result, the user can select to convert the case presentation result into another presentation mode.

According to the embodiment of the disclosure, the method is a method for converting a natural language into an application diagram, a business scene is expressed by a natural language in an application case specification, the application case specification comprises a main scene and an alternative scene, and the two parts are expressed by the natural language. The elements of the scene include vocabularies such as roles, descriptions, verbs, conjunctions and the like, in order to ensure effective and accurate word segmentation conversion between the activity diagram and the natural language, a standard lexicon needs to be constructed in advance, wherein the standard lexicon comprises a role lexicon, an action lexicon, an operation object keyword lexicon and the like, standard words of role classes, execution action classes and operation object classes related to corresponding business processes are respectively prestored, and the standard words are used for constructing use case diagrams and are used for filling in corresponding diagram elements in the use case diagrams.

According to an embodiment of the present disclosure, in operation S201, keywords, specifically including a role keyword, an action keyword, and an operation object keyword, are extracted from an operation description natural language for expressing a business operation general flow. For example, described in natural language as: the teller sets up two types of accounts for the user and binds one type of account, and the role keywords extracted from the accounts are as follows: a teller, wherein the action keywords are set and bound; the operation object keywords corresponding to the corresponding action keywords are a second-class account and a first-class account.

According to the embodiment of the present disclosure, specifically, in operation S202, a character lane diagram for expressing a business operation sub-flow performed by each operator character is generated according to each keyword. For example, in the above example, according to the extracted character keyword: teller, action keyword: and opening and binding, and generating a role swim lane diagram corresponding to the second-class account and the first-class account of the operation object keywords under the corresponding action keywords.

The role element of the role lane graph is filled with the role standard words converted from the role keywords: teller (the standard words pre-stored in the standard word bank are also teller, so conversion is not needed here).

The two operation diagram elements of the role lane diagram respectively represent two successive actions executed by the role, and the two operation diagram elements are respectively filled with standard operation words converted from action keywords: opening an account, and associating accounts. The standard operation word is formed by combining an execution action class standard word and an operation object keyword corresponding to the corresponding action keyword, for example, the standard operation word is formed by: opening, and operating object keyword account, which comprises: opening an account; by performing action class criteria words: binding and operating object keyword account, and the following components are formed: and associating the account.

According to the embodiment of the disclosure, the role class standard words, the execution action class standard words and the operation object keywords are obtained from the standard word library, the standard words are used for filling in corresponding diagram elements in the use case diagram to construct and form each role lane diagram, and finally all the role lane diagrams are combined according to the operation sequence of the business operation general flow to generate a use case general diagram for expressing the business operation general flow and show the use case general diagram to a user.

According to the embodiment of the present disclosure, in the above operations, each business operation step is a minimum unit in the graph, each operation step has an operation type, which may be a starting point, an ending point, a judgment step, an intermediate step, and the like, each operation has a corresponding role, which corresponds to a role lane in the use graph, each operation allows owning and accessing its previous step and next step, but not necessarily, for example, the starting point is not the previous step, the ending point is not the next step, the judgment can allow multiple next steps, and each next step has a condition attribute. In addition, the graphical location of the use case diagram may be generated by default, or the user may manually adjust the location and save.

According to the embodiment of the disclosure, in the above operation, after the use case general diagram is generated, manual adjustment can be performed, so as to perfect the display of the business process.

According to the embodiment of the present disclosure, in order to distinguish the new operation or refer to the pre-stored operation condition, a special symbol may be added to the new operation step to mark as the new operation step.

According to an embodiment of the present disclosure, the transformation method based on the use-case method further includes: and adding the business processing rules followed by each business operation sub-flow in each role swim lane graph.

According to the embodiment of the disclosure, although the business process shown in the example diagram is relatively straightforward, the generality is strong, and it is sometimes difficult for business personnel who are unfamiliar with the business process to understand the specific operation method required for executing the business process only by illustration, so that business processing rules that need to be followed by specific operation steps in the business operation sub-process are added at corresponding positions in the use diagram. For example, at the position of the block diagram of the operation diagram element corresponding to the operation step only shown as "open account" in the usage diagram, the business rule followed by executing the operation is added, for example, it may be a description of which kind of account is opened, which information needs to be checked when the account is opened, and the like.

According to the embodiment of the disclosure, by adding the business processing rule followed by each business operation sub-process, for the business with more complex business processing rules, the separation of the processing steps from the business rules to be followed can increase the implementation difficulty of requirement expression and research and development, and the integration through the activity diagram is beneficial to reducing the risk, so that business personnel can be helped to know the specific operation method required by executing the business process, and misoperation in the business execution process is avoided. On the other hand, in the subsequent process of converting the use case diagram into the natural language, the information in the figure element also needs to be combined with the description of the business processing rule so as to convert the use case diagram into the accurate natural language.

Fig. 3 schematically shows a flowchart for extracting keywords in an original natural language for expressing a general flow of business operations according to an embodiment of the present disclosure.

As shown in fig. 3, the method includes operations S301 to S302.

In operation S301, segmenting a word of an original natural language to obtain a character keyword, at least one action keyword corresponding to the character keyword, and at least one operation object word corresponding to each action keyword from the original natural language; and

in operation S302, an operation object keyword corresponding to each action keyword is determined from at least one operation object word corresponding to each action keyword. Specifically, the specific operations of the operation are: determining a service type corresponding to a service operation total flow; acquiring the standard weight of each operation object word under the service type; and determining the operation object keywords corresponding to each action keyword according to the standard weight of each operation object word under the service type.

According to an embodiment of the present disclosure, specifically, in operation S301, the original natural language is segmented, the segmentation may be performed on the natural language description input by the user by using a segmentation technology, and the segmentation model may be utilized to implement accurate segmentation in combination with the constructed role library and verb library, for example, "a domain architect logs in an architecture analysis platform and enters approval opinions", and the segmentation is: the method comprises the following steps of 'field architect \ login \ architecture analysis \ platform, input \ approval \ opinion', wherein the role key words are 'field architect', the role key words are used as the roles of operators in the primary flow step of the activity diagram, and the action key words are as follows: "Login", "type in"; the nouns following the action keyword are all operation object words.

According to an embodiment of the present disclosure, specifically, in the above operation S302, since the number of the operation object words may be large, the operation object keyword corresponding to each action keyword needs to be determined from the operation object words, and is used as the filling content in the operation diagram element of the activity diagram flow step. When the operation is executed, specifically, the standard word bank can be queried, and because various keywords under different types of services and the weight of each keyword are recorded in the standard word bank, the standard weight of each operation object word under the service type can be obtained from the standard word bank, the word with the highest standard weight is selected as the operation object keyword, and the operation step with the highest relevance is matched and corresponds to the operation diagram element in the activity diagram.

According to the embodiment of the disclosure, the standard word library includes a role word library, a dynamic word library, an operation object keyword library, and the like, wherein standard words of a role class, an execution action class, and an operation object class related to a corresponding business process, and a weight of each standard word are pre-stored, and when setting the weight, the weight is set according to a word segmentation occurrence ratio. For example: an asset named card-open is described that provides the card-open function for the customer and provides the bound deposit function. The word segmentation and the weight configuration for the word segmentation are as follows: client 3, offer 2, open card 5, function 1, bind 2, deposit 5, function 1. The normalization is as follows: providing 2/14, opening card 5/14, binding 2/14, and saving 5/14, (the participle weight of each asset after standardization adds to 1), and assuming that the keyword is removed to include a customer, opening the card, the weight value corresponding to the service is calculated to be 5/14.

According to the embodiment of the disclosure, the standard words in the standard word bank and the weight configuration thereof can be updated regularly according to business needs. For example, the operator role words with matched positions can be stored as new role words, so that the word bank is updated, and the higher accuracy of word segmentation matching is ensured.

According to the embodiment of the present disclosure, various types of keywords under different types of services and the weight of each keyword are recorded in the standard word library, for example: the keywords are classified into different keywords, such as opening account, offering, binding, saving, etc., and the keywords are weighted differently for different services, assuming that for opening the debit card, the weight coefficient for opening account is 5, the debit card is 3, the saving is 2, and the keywords are 5/10, 3/10, and 2/10 respectively after normalization, and for accessing the debit card, the saving is 7, the debit card is 3, and the others are 0, and the keywords are 7/10 and 3/10 respectively after normalization.

For example, if the action keyword extracted by word segmentation is "open", the standard words that are similar or identical to the semanteme thereof in the standard word library are: and associating, namely matching the 'opening up' as an 'associated' key word, then extracting a standard operation matched with the 'associated' key word from the use case diagram library according to the 'associated' key word, and finally filling the matched standard operation into a diagram element corresponding to the use case diagram.

According to an embodiment of the disclosure: the keywords extracted from the natural language also comprise key conjunctions; each role lane graph also comprises a gateway judgment graph element, wherein the gateway judgment graph element is associated with the key conjunctions and is used for expressing the branch operation of the business operation sub-process; generating a character lane graph corresponding to each character keyword according to each keyword further comprises: and converting the key conjunctions into gateway judgment graph elements.

According to the embodiment of the present disclosure, the keyword links, for example, may be if, then, or vice versa, and these keywords will become important words of the gateway judgment element of the usage graph. In the conversion matching process, if the action keyword is not matched, a corresponding graph node is not generated in the graph element, whether a key conjunctions exist or not is judged, and if the key conjunctions exist, the key conjunctions are converted into gateway judgment elements, for example, a plurality of branches are generated.
