Web data processing method based on form concept analysis

Abstract

The invention relates to a Web data processing method based on formal concept analysis. The method comprises the steps of analyzing the latent semantic relation of Web services on each granularity level by using the prior Web service describing information, expressing the relation between the services by using a concept lattice so as to realize concept grouping of the Web services, and providing an increment maintenance method for a service lattice to realize Web service management. A reduction method for the service lattice is provided through research on the similarity of the services under the condition of gradual increment of Web service quantity and category in Internet environment. The established service lattice carries out service search according to service request.

Description

technical field [0001] The invention belongs to the technical field of Web and database, relates to a novel and efficient Web data processing method based on formal concept analysis, and specifically relates to a Web service management and retrieval method. Background technique [0002] With the rapid development of e-commerce, more and more enterprises transfer their core business to the Internet. The service mode of e-commerce develops from business-customer mode to business-commercial mode, and technically develops from simple Web information publishing to data integration and information sharing within the Internet. In this way, higher requirements are put forward for the rapidity, effectiveness and reliability of commercial application systems on the Internet. In this context, Web service technology emerges as the times require. More and more applications show that Web service, as a new type of distributed computing model, has become an effective technical means of da...

Problems solved by technology

There are following deficiencies in organizing Web services in this way of catalog classification: (1) In most cases, a service can perform multiple functions, and if these functions are very different in category, then it cannot be implemented on the service layer. Accurately determine which category the service belongs to; (2) Web services organized in this way, because the potential semantic relationship between services is not effectively used, especially in the case of a large number of Web services, it is difficult to accurately and accurately identify Web services. Efficient retrieval; (3) Due to the traditional Web service management method, the Web service is only organized at a coarse-grained level (service layer), and the needs of the service requester are realized by the methods in the service, while the traditional Web service Service classification management technology cannot meet this retrieval requirement

For the shortcomings of (1), a feasible solution is for the service provider to register a Web service into multiple categories according to its own business purpose and the functions provided by the service, but this will cause the Web service information stored in the service registry to There is a lot of redundancy

For the shortcomings of (2) and (3), the current service management technology cannot directly solve them

Although the existing research on Web service management proposes solutions to overcome the above shortcomings from different aspects, it does not mention the discovery and management of inter-service relationships, how to deal with service failures, and service incremental changes.
