基于语义分析的产品分类本体查询研究1

摘要

Based on ful y understanding the importance of product classification and analyzing the research status,we analyze the structure of the product classifications;Based on five inherent defects of product classification,we propose a model of product classification using semantic analysis method. According to the results of the semantic analysis,we construct a product classification ontology. In order to verify reasoning decidability of completeness,correctness and semantic concept of the product classification ontology,we construct a query model for product classification ontology. The model is composed of the requirements of real queries which are made up of the ontology,the user requests,query processing,query expansion,reasoning rules and query results feedback modules. The model is realized by programming and corresponding experimental system is established. We ran the experimental system,and verified the three characteristics in our hypothesis.%本文在充分理解产品分类的重要意义及分析研究现状的基础上，剖析了产品分类的体系结构；针对产品分类固有的五大缺陷，提出了产品分类语义分析模型，并依据语义分析的结果构建了产品分类本体。为了验证产品分类本体推理的可判定性、概念的正确性和语义的完备性，建立了产品分类本体查询模型；按照真实查询的要求，该模型由本体解析、用户请求、查询处理、查询扩展、推理规则和查询结果反馈等模块组成；通过编程对该模型予以实现，建立了相应的实验系统；对实验系统进行运行，结果证明了需要验证的“三性”是成立的。
