【摘要】：语义Web服务是语义Web和Web服务相结合的产物，通过赋予Web服务以语义信息来实现服务的自动发现、调用和组合。语义Web服务搜索是语义Web服务研究领域的一个重要的内容，，在语义Web服务的生命周期中有着至关重要作用。而语义Web服务搜索条件的表示方法和处理机制又是实现语义Web服务搜索的一个关键问题。本文面向OWL-S服务描述框架，研究OWL-S服务搜索的语义条件表达式及其处理机制，并开发相应的支撑工具软件，使得用户可以便捷、准确地表述语义Web服务的搜索条件。具体而言，本文的研究内容主要有以下三个部分。第一、通过研究已有的语义Web服务搜索条件表达式和相关知识，在此基础上，针对OWL-S描述框架的特征，提出面向OWL-S服务搜索的语义条件表达式，给出其语法规范和操作语义，并用实例来说明表达式的用法。第二、研究面向OWL-S服务搜索的语义条件表达式的处理机制，阐述表达式的处理机制原理和详细的处理过程，提出表达式正确性检查方法和基于Jena推理机对表达式进行的语义推理的方法，给出对语义条件表达式进行处理的算法。第三、设计并实现语义条件表达式的支撑工具软件。该原型工具包括语义条件表达式的构建与编辑、语义条件表达式的语法正确性检查、表达式的语义推理及转换、语义Web服务资源搜索动作的生成等功能模块。
[Abstract]:Semantic Web services are the combination of semantic Web and Web services. Semantic Web services are endowed with semantic information to realize the automatic discovery, invocation and composition of services. Semantic Web services search is an important part of semantic Web services research and plays an important role in the life cycle of semantic Web services. The representation method and processing mechanism of semantic Web service search condition is a key problem to realize semantic Web service search. In this paper, the semantic conditional expression and its processing mechanism of OWL-S service search are studied, and the corresponding supporting tool software is developed, which enables users to express the search conditions of semantic Web service conveniently and accurately. Specifically, the research content of this paper has the following three parts. First, by studying the existing semantic Web service search conditional expressions and related knowledge, according to the characteristics of the OWL-S description framework, a semantic conditional expression for OWL-S services search is proposed, and its syntax specification and operation semantics are given. Use an example to illustrate the expression. Secondly, the processing mechanism of semantic conditional expression for OWL-S service search is studied, and the principle of expression processing mechanism and the detailed processing process are expounded. The method of checking the correctness of expression and the method of semantic reasoning based on Jena inference machine are proposed. The algorithm of processing semantic conditional expression is given. Thirdly, the supporting tool software of semantic conditional expression is designed and implemented. The prototype tool includes the construction and editing of semantic conditional expressions, the grammatical correctness checking of semantic conditional expressions, the semantic reasoning and transformation of expressions, the generation of semantic Web service resource search actions, and so on.
