英文摘要：

[ Purpose/significance ] This paper aims to study the issue on dynamic acquisition and transboundary fusion of small data of researchers from the perspective of ＂Internet ＋ ＂. [Method/process ] It analyzes the connotation and characteristics of small data, and clarifies the source and constitution of small data of researchers. Furthermore, the significances of small data fusion is expounded from the perspectives of researchers＇ environment, researchers＇ requirements and scientific research pattern. On this basis, the paper discusses the main principles and specific process of small data fusion. [ Result/conclusion] Small data fusion has four levels of basis, association, feature and requirement. It is an important way to effectively promote the fusion innovation with the data acquisition, data association, feature extraction and knowledge demands. This pattern provides a support for the prediction of potential demands and push of personalized serv- ices.
