Embodiment Construction

[0026] In order to describe the present invention more specifically, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] The present invention combines the two by constructing a knowledge map of requirements in the e-commerce field and a formal language describing the requirements in the e-commerce field, and designs a set of demand description models oriented to the e-commerce field. The specific steps are:

[0028] S1. Collect a large number of demand documents in the e-commerce field, and convert these documents into text data in a unified format and language; after obtaining the demand documents, the documents need to be preprocessed to remove non-Chinese characters, pictures, and repetitions that appear in the documents Appearing characters, etc., use the text extraction technology to retain the text content related to the requirement description in the document....

Abstract

The invention discloses a demand description model design method oriented to the field of e-commerce based on a knowledge graph. A specific language facing e-commerce field demand description is used,and a powerful knowledge reasoning capability of a knowledge graph is combined, so that a demand descriptor can be helped to more accurately obtain a real demand of a user when the user describes thedemand, demand description can be rapidly completed, and development work can be smoothly promoted. According to the invention, a set of formalized languages designed for the e-commerce demand description field is designed; the method has the advantages that the requirement description of the user is more accurately completed by utilizing the ambiguity of the formalized language, and meanwhile, the user is helped to complete the requirement description and verify whether the requirement description is reasonable or not by utilizing the powerful reasoning capability of the knowledge graph in combination with the formalized language. In addition, the invention also provides a function of automatically generating the UML diagram from the formalized language described by the demand, so that the workload of describing the demand by the user is further reduced, and the working efficiency of the user is improved.

Description

technical field [0001] The invention belongs to the technical field of e-commerce business software development, and in particular relates to a demand description model design method for the e-commerce field based on knowledge graphs. Background technique [0002] The rapid development of the modern service industry, rapidly changing service scenarios, and ever-changing user needs make traditional business process modeling methods increasingly weak. The software requirement stage is the first stage in the software development process. A good requirement description model can avoid costly reconfiguration of the system in the later stage of design, coding and implementation, thereby reducing the risk of software development. Software requirements mainly include functional requirements and non-functional requirements. Functional requirements require the functions that the software needs to realize, while non-functional requirements refer to the quality attributes and functional...
