利用问句语义结构构建旅游领域数据库查询

Building Database Query in Tourism Domain Using Questions Semantic Structure

为了提高数据库查询的准确率,提出一种利用问句语义结构构建领域自然语言数据库查询方法。该方法通过定义问句语义模板,借助领域知识,对领域问句进行语义分析,提取问句语义块,并通过语义模式匹配实现问句语义模板向SQL的转换,从而实现自然语言数据库查询。在云南旅游领域实验的结果表明,该方法取得了较好的效果。

In order to improve the accuracy of the database query,a method of using questions semantic structure to build domain natural language database query was put forward. With the help of domain knowledge, this method makes a semantic analysis to domain questions, extracts questions block by defining questions semantic model and matching semantic pattern to achieve the conversion from questions semantic model to SQL,there by realizes the natural language query. And experiment results in Yunnan tourism domain showed that the method is effective.
