太原理工大学硕士研究生学位论文在语义检索系统中的应用。 太原理工大学硕士研究生学位论文 在语义检索系统中的应用。 在分析理论的基础上，我们构建了基于TAP的上下文知晓框架，其 核心是上下文知晓模块。上下文知晓模块包括有上下文的获取、上下文 的解释、上下文融合、上下文知识库、有哪些信誉好的足球投注网站项分析、知识查找等。我们 对各个模块进行了详细的描述，重点是对上下文的统一知识表示和知识 查找算法的论述。 最后设计与实现了基于TAP的上下文知晓实验子系统。该子系统中 的上下文主要指用户上下文。我们搭建了实验环境，具体实现了用户接 口和上下文知晓模块中的上下文知识库、有哪些信誉好的足球投注网站项分析和知识查找模块以 及通过GetData接口对TAP知识库数据的访问。 本论文的研究工作能够对上下文知晓和知识查找的发展起到一定的 促进作用。 关键字：语义网，TAP，上下文，上下文知晓，RDF II STUDYING STUDYING ON CONTEXT．AWARE FRAMEWORK BASED ON TAP AB STRACT As improvement and development of web techniques，Semantic Web represents the next generation Web．Semantic Web is an extension of current Web in which information is given well·defined meaning and makes computers and people work in cooperation．A number of technical issues will need to be solved before the vision can be realized．TAP is a project at the Knowledge Systems Lab of Stanford University，which is trying t0 address some of these problems．As a semantic web test-bed，TAP identifies and researches many different technical issues，which has an important part in developing semantic web．Moreover，current Information Retrieval and Semantic Search lacking of interaction between users，hasn’t combined some context information，SO fails to understand users’real intent．Consequently, context-aware model based on TAP is presented，which aims at improving querying efficiency by making use of context information．The main work of the thesis iS as follows Firstly，the concepts of context and context-aware are summed up．Several context applications in artificial intelligence are analyzed．Context。aware III 太原理工大学硕士研究生学位论文system 太原理工大学硕士研究生学位论文 system architecture and techniques are illustrated，and new development of context in semantic web iS indicated Secondly，this thesis introduces the development of semantic web and relevant techniques，studies on the key techniques of TAP(core interface GetData，Reference By Description and Data Model)and the components of TAP(TAPache，Registry，TAP KB，Information Extraction)，and give semantic search applications
