Problems solved by technology

[0004] 1) The subjectivity of expert judgment is strong, and at the same time, the knowledge of experts is limited, and there may be huge deviations between expert judgment and objective facts
[0005] 2) The expert judgment method needs to coordinate many experts to discuss and make decisions, which consumes huge manpower and material resources, and its timeliness is also relatively poor
However, citation analysis methods have a time lag and may overlook potential research fronts

Abstract

The invention belongs to the technical field of data mining and utilization, and discloses a word meaning and word co-occurrence information fused research frontier identification method and equipment. The method comprises the following steps: carrying out time slicing on paper data; extracting technical keywords from the paper data of the single time slice; counting the co-occurrence frequency of the technical keywords to construct a word co-occurrence network; forming a semantic similarity network according to the similarity of the technical keywords; fusing the word co-occurrence network and the semantic similarity network to construct a semantic co-occurrence network, and clustering the technical keywords into a plurality of clusters; clustering the semantic co-occurrence networks of all the time slices; performing similarity calculation on the clusters of the adjacent time slices to form a topic evolution venation graph; meanwhile, the research theme which is short in theme age, high in theme development rate and high in theme popularity is the leading-edge theme, and the popular technology in the leading-edge theme is the research leading edge. According to the invention, research frontier identification can be carried out more objectively and accurately.

Description

technical field [0001] The invention belongs to the technical field of data mining and utilization, and more specifically relates to a research frontier identification method and equipment that integrate word semantics and word co-occurrence information. Background technique [0002] In today's world, science and technology have developed to an unprecedented height. Global scientific and technological innovation presents new development trends and characteristics. A deep understanding and accurate grasp of the frontiers of scientific and technological development and innovation trends in the field play a vital role in the forward-looking deployment of innovation strategies and the optimal allocation of innovation resources. Research frontiers are the most potential, forward-looking and leading research directions in the process of technological innovation. Effectively identifying the frontiers of development in the field can make effective predictions about future research ...
