Method for building interlocution service based on Web Service combination

Abstract

The invention provides a question / answer service construction method based on Web service combination for providing answer for a question proposed by current user from Web service resource; the method is characterized in that the method includes the following steps: the correlation situation of all Web services included in Web service resource and in a layer or more than one layer is adopted to determine the directed relation between each two Web services; a Web service directed relation network is established; Web service capable of answering the question proposed by the current user is selected from Web service resource to establish a service layering network diagram; a plurality of service flow combined strategies for answering the question of the current user are searched from Web service set and used as optional answering proposals; so the user can select the optimum answering proposal from the service flow combined strategies to answer the question proposed by the current user. The invention adopts the technical measurement of automatic Web service combination to generate question / answer service software capable of answering questions in the same type; thereby, complicated cross-discipline and cross-system questions can be answered.

Description

technical field [0001] The invention belongs to the technical field of software engineering, in particular to a question answering service construction method based on Web Service combination. Background technique [0002] Since Jaseph implemented Eliza, the first question-answering system in 1966, people have been exploring technologies that allow machines to help answer the information people need. The current question answering system is mainly divided into the following three categories according to the technical methods adopted: [0003] (1) Keyword-based question answering system [0004] Such systems, represented by Zhizhi, Aiwen, Qihoo, etc., use mature keywords and related technologies in the IR field to extract content similar to user questions from web pages and indirectly answer them; Technology looks for the best matching answer to the question. Many scholars have carried out research on such systems and made some progress, such as: by constructing word-sente...

Problems solved by technology

[0009] Among the above three types of systems, the first type is characterized by the fact that the system does not understand the real meaning of the questions and answers, but only provides an asynchronous way to ask questions, and they completely rely on the pre-built question-answer association library; The second type of system focuses on conversational skills and procedural skills rather than knowledge in the process of interacting with users, thereby avoiding domain knowledge base problems, but the content returned is often not the answer that users need

The third type of system improves the semantics of the question answering system through Semantic Web-related technologies, and effectively uses Web services to answer questions, eliminating the task of knowledge base maintenance, but it is limited to certain types of applications, and does not have a software construction methodology. Provide general technical means for producing such software services
