Embodiment Construction

[0053] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0054] Such as figure 2 As shown, a data retrieval and sorting system includes a user management module, a database and a correlation calculation module.

[0055] The user management module is used to manage user information, mainly recording data such as user age, technical title, education background, technical field, and user preference keyword table.

[0056] The database is mainly used to store document data, classify and manage documents, and respond to user application requests for various documents.

[0057] The correlation calculation module is mainly used to realize the calculation and sorting of retrieval results, including the user behavior statistics sub-module and the sorting correlation calculation sub-module.

[0058] The user behavior statistics sub-module is mainly used to record the user's document application behavior reco...

Abstract

The invention relates to a data retrieving and sorting system and method. The system comprises: a user management module, used for managing user information; a database, used for storing documents by classification and making a response to a user request; and a correlation calculation module, used for calculating and sorting retrieval results, wherein the correlation calculation module comprises a user behavior statistics sub-module used for making statistics on keywords of user preferences, comments of a user on the documents and application behaviors, and a sorting correlation calculation sub-module used for calculating a sorting correlation and sorting the retrieval results according to the sorting correlation. According to the data retrieving and sorting system and method, a data set matched with retrieval words is further subjected to analysis and calculation of query correlation (RC), demand correlation (DC) and data quality correlation (QC), so that the retrieved data set conforms to the user preferences, the comments of the user on the documents and the application behaviors, the correlations between the retrieval results and user demands are improved, and the query time of the user is shortened.

Description

technical field [0001] The invention relates to a retrieval method, in particular to a data retrieval and sorting system and method. Background technique [0002] In the process of data retrieval by existing search engines, most of them use keyword input to search, and the search results are sorted according to the degree of keyword matching. Different users often get the same search results when they input the same keyword. The sorting method of retrieval results does not take into account the individual needs of users and data quality factors. Finding the information you need from a large number of returned information will waste a long time and energy for users. Contents of the invention [0003] The main purpose of the present invention is to solve the above problems and deficiencies, and provide a data retrieval and sorting system that improves data relevance and retrieval accuracy based on user behavior information. [0004] Another main object of the present inven...
