大数据环境下知识发现研究的变化及其发展趋向
The Change of Knowledge Discovery Research and Its Development Trend in Big Data Environmental
摘要
Abstract
With the progress of information technology and the rapid development of knowledge economy, knowledge discovery, as the key process of knowledge innovation and knowledge service, is concerned by academic circles. Data is the starting point of knowledge discovery, so the rise of big data has put forward a new topic for knowledge discovery. In this paper, CNKI and WOS retrieval are used as data sources, and 2012, which is highlighted by big data, is used as a comparative time node. The paper compare the differences before and after 2012, respectively from two aspects at home and abroad, in order to explore the impact of big data on knowledge discovery. Then, through reading and classifying, the paper do content analysis for the knowledge discovery literature after 2012, and review the change and development of the specific research contents of knowledge discovery under the influence of big data. Through the comparative analysis and content analysis, this paper found that the emergence of big data made the key of research on domestic knowledge discovery method from data mining to data preparation and application, while foreign research focus on all stages of knowledge discovery. Domestic research need to strengthen the results evaluation and interpretation stage research of knowledge discovery.关键词
