基于主题模型的旅游信息检索方法——以山西太原“晋祠”信息检索为例

Tourism Information Retrieval Method Based on Theme Model: Taking the Information Retrieval of "Jin Temple" in Taiyuan,Shanxi Province as an Example

以旅游信息特征为基础,对构成旅游的主题信息进行分层组织,把旅游信息做实例化处理,并就用户可能提出的问句类型定义了不同的查询模板,以帮助用户在海量的网络数据中获取所需的旅游信息。主题模型中各层主题之间具有关联性,经过主题与地理的相关度计算,可有效避免同义词与语义相关性对检索结果的影响,为用户提供多元化、个性化的检索信息。本文以山西太原“晋祠”信息检索为例,构建不同的问句类型,探讨了在实际应用中的检索精确度。

Based on the characteristics of tourism information,this paper hierarchically organizes the theme information of tourism,in-stantiates the tourism information,and defines different query templates for the types of questions users may ask,so as to help users get the tourism information they need from the massive network data.In the theme model,there is a correlation between the themes of each layer.Through the calculation of the correlation between themes and geography,the influence of synonyms and semantic correla-tion on the retrieval results can be effectively avoided,providing users with diversified,and personalized retrieval information.Taking the information retrieval of"Jinci Temple"in Taiyuan,Shanxi Province as an example,this paper constructs different question types and discusses the accuracy of retrieval in practical application.
