摘　　要：勘探开发档案的非结构化信息快速检索方法在检索的过程中无法高效精准地处理海量数据信息,导致最终检索数据的效率过低,影响检索结果。针对此问题,提出基于知识图谱的勘探开发档案非结构化信息快速检索方法。根据非结构化信息的数据特点抽取检索所需信息,分类抽取区域,将其划分为3个实体空间,及时获取精准的初始信息;进一步构建知识图谱模型,利用隐马尔科夫模型分析非结构化信息的检索模式,按照信息的结构特征建立信息文本模型,精准检索信息传导路径。实验结果表明,所提方法的检索效率较高,查全率为93%,查准率为85%,说明所提方法能够有效实现信息快速检索。The fast retrieval method for unstructured information of exploration and development archive cannot deal with the massive data efficiently and accurately,which leads to the low efficiency of the final retrieval data and affects the retrieval result.In order to solve this problem,a fast retrieval method for unstructured information of exploration and development archive based on knowledge atlas is proposed.According to the data characteristics of unstructured information,the information needed for retrieval is extracted,and it is divided into three entity spaces,so as to obtain accurate initial information in time.This paper further constructs the knowledge atlas model,analyzes the retrieval mode of unstructured information by hidden Markov model,establishes the information text model according to the information structure characteristic,and searches the information transmission path accurately.The experimental results show that the retrieval efficiency of the proposed method is higher,the recall rate is 93%and the precision rate is 85%,which indicates that the proposed method can effectively realize fast information retrieval.
