摘要
知识服务已广泛应用于图书情报领域。大数据时代,单一、保守的地质资料信息服务模式已经难以满足用户的需求,面向知识服务实现地质资料的管理势在必行。知识服务的特点是基于知识内容,以用户需求为中心,融入用户决策,提供解决方案。地质资料与图书情报具有共性,蕴含着海量的知识信息,是科技情报工作的基础。该文在分析地质资料现状的基础上,提出基于本体构建地质数据组织模型、基于关联数据实现地质资料机构知识库的语义扩展的思路,以及面向地质大数据的语义检索机制,促进地质资料管理向知识服务转型。
Knowledge service has been widely used in the field of library and information.In the era of big data,the single and conservative geological data information service mode has been difficult to meet the needs of users.It is imperative to realize the management of geological data for knowledge service.The characteristics of knowledge service are based on knowledge content,centered on user needs,integrated into user decision-making,providing solutions.Geological data and library information have the same characteristics,which contain a large amount of knowledge information,and are the basis of scientific and technological information work.Based on the analysis of the current situation of geological data,this paper puts forward the idea of building geological data organization model based on ontology,realizing semantic expansion of geological data institutional repository based on related data,and semantic retrieval mechanism for geological big data,so as to promote the transformation of geological data management to knowledge service.
