中文摘要：

针对现有五元组比较句语义要素框架的缺陷,该文引进了提升语义分辨率的七元组语义要素分类模板。在此基础上建立了一个可视化的＂比＂字句结构分析模型,用以总结出比较对象之间的三种对应模式,并确立了判定＂不对称比较＂的形式标准。该文的可视化分析模型可以明确阐述＂比＂字句内部的多重述谓结构,有助于获取容易被忽略或认错的隐含成分及比较关系。而且,它立足于谓词逻辑的基础形式,所以与OWL本体语言相兼容。作为模型的应用实践,该文还建设了小规模知识本体（ontology）,演示了＂比＂字句语义要素的自动识别过程。

英文摘要：

In this study,apropositional representation model for Chinese BI（比）-structure is described.The model is based on 7types of Comparative Elements（CEs）,enhancing the resolution of existing 5CE-based framework in analysis of comparatives.The model is also fully visualized by the relational structure of two propositional descriptions,based on which we reveal three basic patterns of comparison and define the standard of asymmetrical comparison explicitly.Consequently,it provides intuitive and easy way to analyze complex,multi-layer predications embedded in BI-structure,which are mostly elusive and tricky part of the comparative relation extraction.Moreover,the model is compatible with the OWL ontology language due to its basis of propositional logic.Accordingly,a smallscale ontology is built to demonstrate automatic relation extraction of BI-comparatives.
