基于对象关系型数据库的多级地名地址服务研究

地名地址服务是网络地图服务的基础服务,其搜索效率和准确性对于用户体验来说至关重要。传统的地名地址服务通常基于全文索引实现,对于检索结果的排序主要根据与用户检索关键词的关联性来考虑。然而在实际应用中,常常需要对检索结果进行分级分类排序。基于Postgre SQL建立索引实现地名地址快速检索,探讨了地名地址全文检索技术与优化方案,通过修改分词字典和使用分级分类信息来优化检索结果,设计并实现了地名地址检索服务架构,进行了性能测试,证明其在大数据环境下可以提供给用户更好的检索体验。

Research on Multi-level Geographical Names and Addresses Service Based on Object Relational Database

Geographical names and addresses service is the basic service of network map service, and its search efficiency and accuracy are very important for the user experience. Traditional geographical names and addresses service is usually based on full-text index. The ranking of search results is mainly based on the relevance with the user's search keywords. However, in the practical applications, the search results are often classified and sorted. This paper is based on PostgreSQL gin index to achieve the rapid retrieval of geographical names and addresses, discusses how to optimize the search results by modifying word segmentation dictionary with the hierarchical classification information, designs and realizes the architecture of geographical names and locations service, carries out the performance test, and provides a better retrieval experience for the users under the environment of big data.
