Abstract:

As a new developing research area big data, has gained widely attention from different fields. This paper analyzed the research articles on big data from Web of Science database using Stanford Topic Modeling Toolbox for content mining. The result show that big data research are clustered into three groups of 15 topics, i.e. groups of risk controlling under big data environment, core technologies for big data, big data in specific fields and applications. A majority of the topics are about core technologies, big data in specific fields and applications. Au of the 15 topics are developing at high speed; meanwhile, big data in specific fields and applications outstands others and is going to be the most attractive research hotspot in the future.

Key words: Big data, Content mining, Topic model, Research trend
