Information retrieval-oriented information map generation method and dynamic updating method

Abstract

The invention discloses an information retrieval-oriented information map generation method and dynamic updating method. A document weight is calculated for a user retrieval result, and data visualization is performed according to the document weight so as to generate an information map; and a user retrieval demand is optimized through interactive operation, and the information map is dynamically adjusted and updated. The information map generation method specifically comprises the steps of establishing a target document set and constructing a hierarchical knowledge concept generation system; preprocessing the target document set; inputting a retrieval demand by a user, performing calculation to obtain a domain feature and a scale feature of the retrieval demand, generating an initial retrieval result and performing sorting; and generating the information map by the initial retrieval result according to the sorting through a data visualization method, and performing display. According to the information retrieval-oriented information map generation method and dynamic updating method, the user can retrieve the information and display the retrieval result more visually and flexibly, and the problems in information retrieval-oriented information map generation and dynamic updating are solved.

Description

technical field [0001] The invention relates to the technical field of information retrieval and visualization, in particular to an information retrieval-oriented information map generation method and a dynamic update method thereof. Background technique [0002] Existing information retrieval methods and technologies, such as mainstream search engines such as Google, Bing, and Baidu, generate retrieval results by analyzing the retrieval requirements submitted by users, and usually display the retrieval results to users for browsing in the form of information items. Existing information retrieval methods have the following disadvantages: [0003] 1) The ability to present information is limited, the search results are generally tiled and displayed in order, and there is a lack of intuitive relationship display between the search results; [0004] 2) The ability to describe information is limited, and users cannot easily obtain the content distribution of retrieval results; ...

AI Technical Summary

Problems solved by technology

[0003] 1) The ability to present information is limited, the search results are generally tiled and displayed in order, and there is a lack of intuitive relationship display between the search results;

[0004] 2) The ability to describe information is limited, and users cannot easily obtain the content distribution of retrieval results;

[0005] 3) The retrieval process is matched through the user's retrieval keywords, and does not utilize the retrieval characteristics of the user's retrieval needs in a specific professional field;

[0006] 4) Lack of real-time user demand description and interactive means, users cannot easily express further search needs with the help of existing search results;

[0007] 5) The retrieval model is relatively fixed, and the system cannot update the retrieval model as the user's retrieval tendency changes to provide a better user experience
