摘要
地质资料用户在对已有资料进行检索的过程中,都希望快速获取自己想要的内容,节约检索时间。为了达到这一目的,结合地质领域本体概念,参考《地质汉语叙词表2010》,按照一定的地质研究规则,设定筛选地质资料的关键词,采用人工校验的方式,将研究对象按照已有的地质类别进行归纳,构建地质资料本体树。基于本体树,结合信息论的相关知识,以地质资料的关键词组为依据,构建了地质资料相关度的加权计算模型,并对模型的有效性进行了试验。
When geological data users are retrieving, they all want to access what they need really quickly, saving search time as much as possible. Therefore, we introduce ontology into the area of geology,referring to "Chinese geological thesaurus 2010", according to certain rules of geological research, setting geological data keywords, using artificial parity approach, in accordance with some categories are summarized geological, in order to build the ontological tree of geological data. Based on the ontological tree, combined with the knowledge of information theory, relied on the key phrases in geological data, the weighted correlation model of geological data was constructed, and the validity of the model was tested.
