摘要
针对网络上地球物理领域的信息资源复杂多样,而传统的信息检索方法在检索地球物理信息时结果比较片面这一问题,将本体技术与传统信息检索技术相结合,建立了一个基于语义的地球物理信息检索系统模型。研究了地球物理领域的本体特征,并设计建立了本体库;提出了计算地球物理领域本体的语义相似性方法,分析了地球物理爬虫的工作机制;最后编程实现了系统的主体功能,验证了系统模型设计的合理性、可行性。
The geophysics information is complex and diverse in allusion to network,and the retrieve geophysical information are one-sided using traditional information retrieval methods.In order to solve this difficult problem,a semantic retrieval model for geophysical information was established by combining ontology technology with the traditional information retrieval technology.In this system model,the characteristics of geophysical ontology are studied,and the geophysical ontology library is designed,and a geophysical ontology semantic similarity algorithm is proposed,and the working mechanism of the geophys-ics crawler is analyzed.At last,the main function of the system has been realized,and the rationality and feasibility of the model are verified.
