The server 102 may be a server providing various services, and may perform analysis processing according to a request from the client 101, and feed back processing results (e.g., information, data, etc. acquired or generated according to a user request) to the terminal device.

It should be noted that the use case method-based transformation method provided in the embodiments of the present disclosure may be generally performed by the server 102. Accordingly, the use case law based conversion device provided by the embodiments of the present disclosure may be generally disposed in the server 102.

Accordingly, embodiments of the present disclosure provide a use case based transformation method that can achieve inter-transformation between natural language and use case diagrams.

FIG. 2 schematically illustrates a flow chart of a use case based conversion method according to 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 total flow of business operations are extracted, wherein the keywords include at least one character keyword, at least one action keyword corresponding to each character keyword, and an operation object keyword corresponding to each action keyword.

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

In operation S203, all the character lane diagrams are combined in the operation order of the business operation total flow to generate a use case total diagram for expressing the business operation total flow.

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

According to an embodiment of the disclosure, the method is a method for converting a natural language into a use case diagram, wherein a use case specification expresses a service scene by using the natural language, and the use case specification includes a main scene and an alternative scene, which are both expressed by using the natural language. The elements of the scene comprise words such as roles, descriptions, verbs and conjunctions, and in order to ensure effective and accurate word segmentation conversion between the active graph and the natural language, a standard word stock needs to be established in advance, wherein the standard word stock comprises a role word stock, an active word stock, an operation object keyword stock and the like, and standard words of the roles, the execution actions and the operation object are respectively pre-stored in association with corresponding business processes, are used for constructing a usage graph and are used for filling corresponding graph elements in the usage graph.

According to an embodiment of the present disclosure, in particular, in operation S201, extracting keywords from operation description natural language for expressing the total flow of business operations, the method specifically comprises character keywords, action keywords operation object keywords. For example, in natural language: the teller opens two kinds of accounts for the user and binds one kind of accounts, and the role keywords are extracted as follows: the teller, the action key words are opened and bound; the operation object keywords corresponding to the corresponding action keywords are two types of accounts and one type of account.

According to an embodiment of the present disclosure, in particular, a character lane diagram for expressing a business operation sub-process performed by each operator character is generated according to respective keywords in operation S202. For example, in the above illustration, based on the extracted role keyword: teller, action keywords: and opening and binding the two kinds of accounts and the one kind of accounts of the operation object keywords corresponding to the corresponding action keywords, and generating a role lane diagram.

The character map elements of the character lane map are filled with character class standard words converted from character keywords: teller (standard words pre-stored in standard word stock are also teller, so conversion is not needed here).

The operation diagram elements of the character lane diagram comprise two operation diagram elements which respectively represent two sequential actions executed by the character, and the two operation diagram elements are respectively filled with standard operation words converted by action keywords: open an account, and associate an account. The standard operation word is formed by combining an execution action class standard word and an operation object keyword corresponding to a corresponding action keyword, for example, the execution action class standard word is used in the above example: opening and operating object keyword accounts, and forming: opening an account; by the execution action class standard word: binding and operating the object keyword account, and forming: an account is associated.

According to the embodiment of the disclosure, the character class standard words, the execution action class standard words and the operation object keywords are obtained from a standard word library, the standard words are used for being filled in corresponding graph elements in the usage graph to construct and form each character lane graph, and finally all the character lane graphs are combined according to the operation sequence of the total business operation flow to generate a usage total graph for expressing the total business operation flow and are displayed to a user.

According to an embodiment of the present disclosure, in the foregoing operations, each business operation step is a minimum unit in the graph, each operation step has an operation type, which may be a start point, an end point, a judgment, an intermediate step, and so on, each operation has a corresponding role, corresponds to a role lane in the application graph, and each operation allows to own and access to its previous step and next step, but is not necessary, for example, the start point is no previous step, the end point is no next step, the judgment may allow a plurality of next steps, and each next step has a condition attribute. In addition, the graphic location of the use case diagram may be generated by default, and the user may manually adjust the location and save it.

According to the embodiment of the disclosure, in the above operation, after the use case total graph is generated, the operation may be manually adjusted so as to perfect the presentation of the business process.

According to embodiments of the present disclosure, in order to distinguish between new operations or reference to a pre-stored operation, special symbols may be added to the new operation steps to denote the new steps.

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

According to the embodiments of the present disclosure, the business processes represented by the illustrations, while being relatively straightforward, are relatively general, and business persons unfamiliar with the business processes are sometimes difficult to understand by way of illustration only the specific operation methods required to execute the business processes, and thus, the business processing rules to be followed by the specific operation steps in the business operation sub-processes are added at the corresponding positions in the illustrations. For example, business rules to be followed for performing the operation may be added at the positions of the block diagram of the operation chart elements corresponding to the operation steps displayed only with "open account" in the usage chart, for example, it may be explained what kind of account is opened, what information needs to be verified when the account is opened, and so on.

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

Fig. 3 schematically illustrates a flowchart of extracting keywords in an original natural language for expressing a total 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, the original natural language is segmented so as 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 operation of this operation is: determining a service type corresponding to the total flow of service operation; obtaining 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 the embodiment of the disclosure, specifically, in the above operation S301, the original natural language is segmented, so that the natural language description input by the user may be segmented by using a segmentation technique, and the accurate segmentation may be implemented by using a segmentation model and combining the well-constructed role library and verb library, for example, "a domain architect logs in a framework analysis platform, inputs approval comments", and segments the results into: the method comprises the steps of inputting/approving/opinion by a domain architect/login/architecture analysis/platform, wherein character keywords are the domain architects, and the character keywords are the operator characters which are to be used as the primary flow steps of an activity diagram and are as follows: "login", "enter"; nouns following the action keyword are operation object words.

According to the embodiment of the present disclosure, specifically, in the above-described operation S302, since the number of operation object words may be large, it is necessary to determine an operation object keyword corresponding to each action keyword from the operation object words, as the filling content in the operation map element of the activity map flow step. When the operation is executed, specifically, a standard word stock can be queried, and various keywords under different types of services and weights of the keywords are recorded in the standard word stock, so that standard weights of each operation object word under the service type can be obtained from the standard word stock, a word with the highest standard weight is selected as the operation object keyword, and the operation step with the highest association degree 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 character word library, an action word library, an operation object keyword library, and the like, wherein standard words of a character class, an execution action class, and an operation object class related to a corresponding business process, and weights of the individual standard words are respectively pre-stored, and when the weights are set, the weights are set according to the occurrence proportion of the segmentation words. For example: an asset named card open, described as providing a card open function for a customer and a binding saving function. The word segmentation and weight configuration are as follows: customer 3, offer 2, open card 5, function 1, and 1, bind 2, save 5, function 1. The standardization is as follows: providing 2/14, opening a card 5/14, binding 2/14, saving 5/14, (normalized word segmentation weight of each asset is added to be 1), and calculating a weight value corresponding to the business to be 5/14 assuming that the keyword is removed and the customer is opened.

According to the embodiment of the disclosure, standard words and weight configurations thereof in the standard word library can be updated periodically according to service requirements. For example, the character words of the operators matched with the positions can be used as new character words to be put in storage, so that the update of the word library is realized, and the matching accuracy of the word segmentation is ensured to be higher.

According to an embodiment of the present disclosure, in a standard thesaurus, various keywords under different types of services, and weights of the keywords are recorded, for example: keywords of the word include account opening, providing, binding, saving and the like, the weight of the keywords is different for different businesses, the weight coefficient of the account opening is 5 for corresponding debit cards, the debit card is 3, the saving is 2, the normalized saving is 5/10,3/10 and 2/10 respectively, the saving is 7 for corresponding debit card access, the debit card is 3, the other is 0, and the normalized saving is 7/10,3/10 respectively.

For example, the action keyword extracted by word segmentation is "open", and the standard word which is not similar or identical to the semantic meaning of the action keyword is not retrieved in the standard word library is: and (3) associating, namely matching the "on-off operation" into an "associated" keyword, extracting standard operation matched with the "associated" keyword from the use case diagram library according to the "associated" keyword, and finally filling the matched standard operation into the corresponding diagram element of the use case diagram.

According to embodiments of the present disclosure: keywords extracted from natural language also include keywords; each character lane diagram also comprises a gateway judgment diagram element, wherein the gateway judgment diagram element is associated with the key link and is used for expressing the branch operation of the business operation sub-flow; generating a character lane diagram corresponding to each character keyword according to each keyword further comprises: and converting the key interlinking words into gateway judgment graph elements.

According to embodiments of the present disclosure, keywords may be, for example, if, then, vice versa, etc., which would be important words of the gateway judgment element of the use case diagram. In the conversion matching process, if the action keywords are not matched, no corresponding graph node is generated in the graph element, whether the keyword exists or not is judged, and if the keyword exists, the keyword is converted into a gateway judgment element, for example, a plurality of branches are generated.

According to an embodiment of the present disclosure, the above scenario may be, for example: if the customer is a star customer, only a teller is required to take the customer to finish the common card opening on the card opening machine; if the client is a five-star client card opening, the client manager is required to take the window to complete the diamond card opening, and the gateway can be split according to the scene matching keyword: customer level- [ one star level customer ] - [ teller ] machine common card opening, customer level- [ five star level customer ] - [ customer manager ] window diamond card opening.
