摘要

提出了一种基于语用分析的烹饪问答系统查询扩展方法。在我们的方法中，使用了问题分析的结果。首先通过问题主题生成原始查询，然后根据语用功能对查询词进行扩展。当将扩展查询提交到Google搜索引擎检索相关段落时，我们在平均精度上得到了36.2%的总体提高。

Pragmatic analysis based query expansion for Chinese cuisine QA service system

This paper proposes a query expansion method for cooking question answering system based on pragmatic analysis. In our approach, the results of question analysis is used. The original queries are generated by means of the question subject, then the query terms are expanded based on pragmatic function. When submitting the expended queries to Google search engine to retrieve related passages, we get an overall improvement of 36.2% on the mean average precision.
