Abstract

Abstract: To solve the problem of the answer extraction of restricted-domain question answering system，a question answering system model based on shallow semantic parsing is presented.A natural language interface is provided，the ontology of the hospital information is utilized and shallow semantic parsing technology is applied in the model.According to the rules of the definition and determination of semantic chunk，the question vector is firstly generated，then SPARQL query technology is utilized，the answer is obtained by querying in the ontology.The experiments proves that it is feasible to use the method to develop a question answering system，it is valuable for further study in more depth.

Key words: question answering system, shallow semantic analysis, nature language processing

摘要： 为了解决受限域问答系统中答案抽取的问题，提出了一种基于浅层语义分析的问答系统模型。该模型以自然语言为接口，利用医院信息本体，采用浅层语义分析技术，由语义块定义规则和语义块判定规则，首先生成问句向量，然后利用SPARQL查询技术，在本体中进行查询，从而得到答案。实验表明该方法可行，对自动问答系统的设计具有借鉴意义和深入研究的价值。
