Embodiment Construction

[0043] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, and the described specific embodiments are only for explaining the present invention, and are not intended to limit the present invention.

[0044] This paper proposes a method for visual analysis of hotspots in the field, which is mainly used to sort out the past development and changes of a certain discipline, track the latest developments at present, and predict the future development trend of a certain discipline. When using bibliometric methods to analyze literature hotspots, follow the steps described below:

[0045] The first step: determine the field that needs to be studied, and crawl the field journal data;

[0046] Step 2: Extract the required research fields, the keyword fields used here;

[0047] Step 3: Preprocessing the obtained keyword fields, including merging singular and plural keywords, and...

Abstract

The invention discloses a visualization analysis method of a document hot point. The visualization analysis method mainly comprises the steps of 1) researching data acquisition and processing, particularly determining the field needed to be researched, crawling field periodical data, extracting a field needed to be researched, and processing an acquired keyword field; 2) researching subject detection; and 3) visually researching a subject and a subject network. Change is performed from a data source, a data acquisition method is changed, the field periodical is selected, data crawling is performed according to a set condition, a large of representative data relevant to research can be obtained, visualization is performed by a method combining a strategic map and the subject network, a result is analyzed from multiple angles, the accuracy of the analysis can be further improved, and effective analysis and explanation are expected to be performed on research trend in future.

Description

technical field [0001] The invention belongs to the field of bibliometrics, and in particular relates to a visual analysis method for document hotspots Background technique [0002] Literature hotspot analysis is an important research field. Hotspot research mainly analyzes papers or patents published in this field, and papers are an important manifestation of research development in this field. At present, most of the literature analysis is based on the WOS and CNKI databases, directly using the search fields to obtain data, and then using visualization tools for visual analysis. The amount of data obtained using this method is relatively small, and the artificially defined search fields may cause the problem of incomplete search documents, which cannot complete the macro analysis of the entire industry knowledge, and cannot give accurate prediction and analysis of industry development. [0003] Existing solutions are generally based on data directly retrieved from known d...
