Abstract

The invention discloses an analysis method for scientific research literature theme evolution. The method comprises the following steps of A1, downloading scientific research literature of a specific subject, and sorting literature metadata; A2, performing preprocessing on the literature metadata to form a literature data set; A3, performing calculation by using an LDA scientific research literature probability theme model to obtain scientific research keyword distribution and theme literature distribution; A4, dividing extracted themes on the timeline by using time information of the theme literature to form sub-themes in different time periods; A5, building a theme evolution diagram by using the correlation relationship measurement of the themes, and tracking the evolution condition of the scientific research themes. The analysis method and the device for scientific research literature theme evolution provided by the embodiment of the invention have the advantages that the goal of disclosing and mining the changing rule of the scientific research themes in the preset scientific research fields along with the time can be achieved; and the mastering of the evolution process of the scientific research themes can be facilitated.

Description

technical field [0001] The invention relates to a data mining technology in the field of scientific research, in particular to an analysis method and device for subject evolution of scientific research documents. Background technique [0002] Scientific research literature records the achievements of academic research and is an important means for researchers to carry out academic dissemination and academic exchanges. Any scientific research results are obtained by improving and innovating on the basis of inheriting the research results of predecessors. With the development of the network and the establishment of electronic literature resource databases such as IEEE, ACM, and DBLP, the amount of scientific research literature accumulated is increasing. Researchers are often only familiar with the evolution of research topics in their professional field. When researchers enter a new research field, facing such a vast scientific research literature, they are eager to quickly...
