汉语情感问题类型分类研究

Research on Chinese Sentiment Question Category Classification

随着网络搜索引擎技术的飞速发展,对于问答系统的需求愈发迫切。而问答系统处理问题的第一步就需要分辨情感问题和非情感问题并对情感问题进行分类。该文首先分析了当前问答系统和问题分类领域的研究现状,总结了一些存在的问题。然后针对情感问题从三个方面进行分类。在语义层面,提取了三个关键词;在语法层面,通过规则的制定,将其分成五种疑问句类型;在领域层面,通过搜索引擎的相关网页数量来进行判断。再对综合上述三个方面所开发出的测试系统进行分析。实验结果表明:对于情感问题的分类,从三个层面进行分析比较全面。

With the development of search engine,the demand of question answering system becomes pressing.The first step of QA system dealing with question is judging whether a question is an opinion question or a non-opinion question and further classifying opinion questions.The paper firstly analyzes the current situation of QA system and Question Classification,and then summarizes some problems.We analyze the question in three layers.In the semantic layer,we extract three key words.In the syntactic layer,we classify the question into five typical question types by some rules.In the domain layer,we judge the domain by the number of related websites that are obtained via the search engine.Finally,based on three layers mentioned above,we develop a system for experiments and further analysis.The result of experiments shows that for the classification of opinion question,the proposed three-layer-scheme is very useful.
