[0026] See also Figure 1 , the embodiment of the present application provides an academic hotspot analysis system, including:

[0027] The document data acquisition module 110 is used to acquire target field information of a number of documents to be analyzed in a target field, and acquire document data according to the target field information; the document data includes the publication time, keywords and publication unit of the document;

[0028] The target field is used to determine the field of the document to be analyzed, and the target field can be determined according to user needs. In the embodiment of the present application, the target field can be the field of ecological remote sensing.

[0029] The documents to be analyzed can be documents in the target field, for example, documents on the theme of ecological remote sensing. The documents to be analyzed can be documents obtained by searching related topics from academic paper websites such as HowNet and Wanfang.

[0030] Target fields may include basic document information, author information, publication information, reference list, etc. Target fields can be set according to user needs.

[0031] The target field information can be obtained based on the citation data of the custom field exported from the academic paper website.

[0032] In an embodiment of the present application, the target field information may include "SrcDatabase-source library", "Title-title", "Author-author", "Organ-unit", "Source-document source", "Keyword-keyword", "Summary-abstract", "PubTime-publication time", "Year-year", "CLC-China Library Classification Number", "ISSN-International Standard Serial Number", "URL-website", "DOI-DOI" and other information of the document to be analyzed.

[0033] The document publication trend display module 120 is used to generate a document publication trend interface by counting the number of document publications in each year based on the document data;

[0034] The document publication trend interface can be used to display information such as the total number of documents, coverage years, high-yield years, average annual publication volume, cumulative growth rate, moving average trend, etc. The document publication trend interface can be used to display the documents of each year.

[0035] The keyword trend display module 130 is used to receive document data, count the time and number of occurrences of each keyword in the document data, and generate a keyword trend interface;

[0036] The keyword trend interface is used to display the number of times a keyword appears and the time of its appearance, generate a dynamic evolution map, and intuitively reveal the germination, diffusion, and transfer trajectory of research hotspots in the field, providing a quantitative basis for field trend analysis.

[0037] The publishing unit display module 140 is used to receive document data, call a preset map API to convert the publishing unit name in the document data into longitude and latitude coordinates, draw a heat map of each publishing unit of the document data according to the longitude and latitude coordinates, and generate a publishing unit display interface.

[0038] The map API may be an API of existing map software such as Baidu Maps.

[0039] Specifically, the publishing unit name can be converted into longitude and latitude coordinates by calling the geocoding service of the Baidu Map API. The geocoding service can be used to convert between longitude and latitude coordinates and structured address information. In the embodiment of the present application, the geocoding service of the Baidu Map API is used to convert the publishing unit name into longitude and latitude coordinates to obtain the confidence level of the address coding.

[0040] International tools (such as CARTO) rely on the Google Maps geocoding interface and cannot accurately parse Chinese institutional naming conventions (e.g., "Northeast Institute of Geography, Chinese Academy of Sciences" vs. "Northeast Institute of Geography and Agroecology, Chinese Academy of Sciences"). Furthermore, due to restrictions on domestic map service policies, coordinate offsets (average error >1.5km) are common in practical applications. Such tools have a failure rate exceeding 45% when parsing scientific research institutions below the provincial level, severely hindering regional research layout analysis. This application utilizes the Baidu Maps API's geocoding service to convert latitude and longitude coordinates into structured address information, improving the accuracy of regional research layout analysis.

[0041] Heat maps can be used to display the popularity of literature publications in different regions, reflect the spatial distribution differences of research, and facilitate the analysis of regional research preferences.

[0042] The academic hotspot analysis system of the embodiment of the present application can be developed based on the R language. The R language has strong capabilities in data analysis visualization and is open source, which helps to improve research efficiency and quality and promote the development of academic research.

[0043] The academic hotspot analysis system can be built based on the biblioCNKI package, an open-source bibliometric toolkit designed in the R programming language. Developed specifically for HowNet, this bibliometric toolkit can effectively parse citation data exported from HowNet, improving data processing efficiency and accuracy. Other bibliometric tools, such as CiteSpace, lack Chinese word segmentation and institutional hierarchy parsing algorithms. Their comma-delimited format is incompatible with the special delimiter (";") used in HowNet-exported citation data. This requires manual preprocessing, impacting data processing efficiency and resulting in a high statistical error rate (as high as 37% when testing 5,000 data points).

[0044] In an embodiment of the present application, the document data acquisition module can be constructed based on the analysis function in the biblioCNKI package. By performing data cleaning on the target field information exported from HowNet and outputting document data such as the year of paper publication, number of publications by the author, document source, and publishing unit, a data basis is provided for bibliometric analysis.

[0045] The document publication trend display module 120 can be constructed based on the cumulative function in the biblioCNKI package. The document publication trend display module 120 extracts the document publication time, calculates the number of document publications each year, generates a chart showing the change in the number of document publications over time, and uses ggplot2 for visualization.

[0046] The keyword trend display module 130 can be constructed based on the Keydumbbell function in the biblioCNKI package. The keyword trend display module 130 processes the document data, extracts the document keywords and associates them with the publication time to generate a dynamic evolution graph.

[0047] The publication unit display module 140 can be constructed based on the Geoheatmap function in the biblioCNKI package. Specifically, it uses the geocoding service of the Baidu Map Open Platform to reverse-parse the publication unit name into longitude and latitude coordinates. The module then renders the spatial distribution kernel density based on the online image map of the China Science Star Map. Users can interactively zoom in and out to locate the heat level of a specific province, automatically annotating high-density research clusters, intuitively reflecting the spatial distribution differences of research and supporting the analysis of regional research preferences.

[0048] In an embodiment of the present application, a document data extraction module is used to obtain target field information of several documents to be analyzed in the target field, and document data is obtained based on the target field information. The document publication trend display module is used to analyze the document publication trend and generate a document publication trend interface to realize the visualization of the document publication trend. The keyword trend display module is used to analyze the time and number of occurrences of each keyword to generate a keyword trend interface for displaying the development trend of research hotspots. The publishing unit display module is used to call a preset map API to convert the publishing unit name in the document data into longitude and latitude coordinates, and a heat map of each publishing unit is generated based on the longitude and latitude coordinates, thereby realizing the display of academic preferences in different regions. The embodiment of the present application can analyze the distribution of document publication trends, keyword trends and publishing units and generate a visualization interface, which can intuitively display academic research hotspots, development trends and regional popularity, facilitate scientific research layout, improve academic research efficiency and quality, and promote the development of academic research.

[0049] The publication trend display module 120 analyzes and compiles literature data, generating a publication trend analysis chart for the corresponding year. The publication trend interface allows users to select an analysis time period to generate a publication trend analysis chart for the corresponding time period.

The data summary interface 320 displays the time range of the first target time period, the total number of documents, the number of covered years, the most productive years, the average number of publications, the cumulative growth rate, and the moving average trend.

[0066] In the embodiment of the present application, the user can trigger the data summary control to display the publication information of the documents in the first target time period, so as to facilitate the understanding of the publication status and trends.

[0067] Specifically, the keyword trend display module 130 can analyze the distribution coordinates of the keywords in the first quartile, median, and third quartile, associate their spatial positions in the trend map, and simultaneously count the frequency and quantity of keywords in each year period to generate and display the keyword trend interface.

[0068] In one embodiment, the keyword trend interface includes a second time period input control, a keyword quantity adjustment control, a color input control, and a keyword time distribution trend graph. The keyword trend display module includes:
