Method and system for spreading UDDI realize semantic and personalized enquire

Abstract

An expanded UDDI implementation semantic and individualized inquiry method and a relevant system, expands prior schemes for UDDI registration structure and completes centralized description and problem detection for resources and service. Through centralized description for the resources and service, users can suitably select required contents according to local network conditions. Meanwhile, the invention improves the defect that prior UDDI registration information inquiry can only be performed based on key words and simple category methods, and submits an interactive inquiry process. The process changes the prior policy of only sending service inquiry once from users' end before returning results, but fulfill the target in a user interactive mode. Perform more effective collection for users' preference information from original registration information, local documents and history records and etc., in order to accurately and reasonably return inquiry results. Besides, compared with key word searching, OWL object description language can more effectively describe relationship between all services. The invention also service end provides a semantic inquiry mode based on a main body model.

Description

Technical field [0001] The invention belongs to the field of computer network technology, and relates to expanding an existing UDDI registration center and providing semantic and personalized queries, and in particular to a method and system for expanding UDDI to realize semantic and personalized queries. Background technique [0002] Network service is a relatively complex technology, which is based on many other related technologies. First of all, web services use XML as the lowest data transmission format, which makes it have all the advantages of XML. Secondly, at the application layer, the web service uses the Simple Object Access Protocol (SOAP-Simple Object Access Protocol), which is based on XML and solves the problem of remote invocation of web services. Finally, the web service adopts WSDL-Web Service Description Language (WSDL-Web Service Description Language) for unified service description. In order to realize that a ready-made network service can be discovered and u...

Problems solved by technology

This method has two main defects: on the one hand, the single keyword search method only uses keywords as the input of the query, and the query information is less; on the other hand, the keyword-based search method does not include the relationship between information

However, because the UDDI registration center only provides a keyword matching query method, it lacks service support for semantic query, resulting in some information loss

At the same time, it is only based on the query mode of the keywords provided by the user, and cannot extract the corresponding service information according to the user's preferences.
