知识元视角下的社会科学开放数据标引研究

A Study on Open Data Indexing of Social Sciences Based on Knowledge Element

引入知识元的概念,在知识元已有研究的基础上,以开放获取目录(OAD)中社会科学数据为例,通过知识元界定、抽取、链接等步骤和关键技术对开放科学数据进行标引,最终形成基于知识元的社会科学开放数据标引模型,从而支持开放科学数据的知识发现与再利用服务,为开放数据转化为开放知识提供方法借鉴与参考。

Using the concepts involving knowledge element and based on current researches on it,this paper indexes the open scientific data by key technologies such as knowledge element identification,extraction and linkage.The social sciences datasets are chosen from Open Access Directory（OAD）.In the end,an open scientific data indexing model of social sciences based on knowledge element is presented,supporting the discovery and reuse service of open scientific data.Some references are provided to the methodology of transforming open data to open knowledge.
