Web service providing method based on customer preference

Abstract

The invention discloses a method for providing Web service based on a user preference. The method comprises the following steps: establishing a Web service composition template library which at least comprises a Web service composition template profile as well as a list and a process for abstract service, which are all described by an ontology concept in an ontology library; ensuring the preference degree of a user to the ontology concept; and searching a Web service composition template which is matched with a Web service request according to the Web service request of the user, if the Web service request is matched with the Web service composition template, the Web service composition template is provided to the user, otherwise, new service composition is constructed, and the constructed new service composition is provided to the user. The invention collects and analyzes preference information of the user in a quantized way and recommends the most suitable Web service to the user according to the obtained preference information of the user, therefore, the needs of the user are satisfied with the rapidest speed.

Description

technical field [0001] The present invention relates to a method for providing Web services, more specifically, a method for providing Web services based on user preferences. Background technique [0002] With the rapid growth of the number of services in the Web environment, how to dynamically combine services automatically according to service requests has become an urgent problem to be solved. Aiming at this, industry and academia have done a lot of research on Web service composition from different angles, and proposed various technologies and systems of Web service composition. From the methodological point of view, these technologies can be roughly divided into the following three categories: artificial intelligence-based planning, workflow-based, and software engineering methods, which are briefly introduced below.

AI Technical Summary

Problems solved by technology

The disadvantage of the formal programming method based on scenario calculus is that the planning method based on scenario calculus is too abstract and difficult to apply in real life

The disadvantage of this technical solution is that simply treating Web service composition as a decomposition of complex tasks cannot fully express Web service composition, and the decomposition process does not consider user preference information, and the decomposed Web service does not necessarily meet the needs of users

Disadvantages: Insufficient flexibility, workflow model needs to be defined in advance, and there is no support for semantic information in the combination process, the process of populating abstract activities (Activity) with web services in the execution phase belongs to keyword matching

The disadvantage is that not all services can be abstracted into automata, making it difficult to form the final finite state machine

The technical methods proposed by the industry have good engineering implementability, but there are problems in combination development difficulty, error-prone, developed system flexibility, scalability, etc.

Therefore, it is not very complete in terms of providing Web service combinations to users. In particular, the Web service combinations provided must be able to meet user needs, and there are differences in the needs of different users. Provide users with the combination of Web services they need
