基于地质技术方法非结构化数据的文档检索研究

Research on Document Retrieval Based on Unstructured Data about Geological Technology and Method

文章论述了地质调查技术方法非结构化数据在关系型数据库存储的基础上,进行文档检索技术与方案实现的研究,设计了一个针对多种格式文档进行处理的可扩展的应用服务框架,并在框架中实现对文档的全文和元数据的存储、索引和检索等服务。并对关系型数据库存储和检索非结构化数据的不足进行了分析,提出了以NoSQL数据库支撑地质调查技术方法非结构化数据存储检索的改进方向。

In this paper, we discussed the method of geological survey, based on the storage of relational database, and made a research on the technology and implementation of document retrieval. We designed an extensible application service framework for multi format documents. According to the analysis on the problem of relational database storage and retrieval of unstructured data, we proposed the improvement direction of the data storage and retrieval based on NoSQL database.
