Method for searching Web services according to non-functional requirements of user

Abstract

The invention relates to the technical field of software engineering, in particular relating to a method for searching Web services according to non-functional requirements of a user. The method comprises the following steps: processing a requirement text of the user, and extracting key words from the requirement text; using a noumenon to perform semantic disambiguation on the got key words; identifying the key words representing the non-functional requirements of the user, and mapping the key words to corresponding Web service quality attributes; collecting data of the quantity attributes tobe analyzed in the candidate Web services one by one, and using the cloud transform method to get a corresponding atomic concept set; transforming the got atomic concept set to a corresponding candidate concept set with appropriate grain size one by one; and selecting one concept which is most matched with the key words representing the non-functional requirements of the user from each of the sets respectively, and generating combined constraint conditions for inquiry according to a corresponding cloud model. By utilizing the qualitative and quantitative conversion of the cloud model, the impacts of subjective differences of experts and differences in environmental conditions on the inquiry are reduced, and a result which is closer to expectation of the user is returned.

Description

technical field [0001] The invention relates to the technical field of software engineering, in particular to a method for searching Web services according to non-functional requirements of users. Background technique [0002] In the late 1990s, directly driven by e-commerce applications, Web service technology emerged and rapidly developed into a mainstream technology for constructing cross-domain distributed applications based on the Internet. By abstracting different levels of applications and data resources into a unified form of expression and providing standard usage methods, Web service technology can effectively support service providers to provide their own applications and data resources to users in the form of services without considering specific implementation details, such as programming language, development environment, operating platform, etc.; at the same time, with the support of Service-oriented Architecture (Service-oriented Architecture, SOA), users can...

Problems solved by technology

Therefore, when matching qualitative concepts with quantitative data, it is necessary to further consider the uncertainty of membership, rather than relying on traditional expert prior knowledge or statistical analysis results for training sets, because these methods often have subjective differences, environmental Conditional differences, etc.
