摘要
提出了面向石油勘探开发的空间信息检索技术方法,给出了文档空间主题计算模型,设计了支持文本与三维空间查询的高性能索引结构,在原有研究的基础上实现了原型系统PetroScope.经过真实数据的性能测试和比较分析,原型系统的准确度得到了一定程度的提高,性能能够满足该领域空间信息检索的需求。
A technical framework of spatial information retrieval was put forward for petroleum exploration and production, a method of spatial theme mining proposed and a high-performance hybrid index structure supporting query composed by text and 3 dimensions space were also designed. The prototype named PetroScope based on original research was implemented. It was proved that the PetroScope could meet requirements of spatial information retrieval in petroleum exploration and production with its accuracy and performance verification.
