Problems solved by technology

The disadvantage of this type of retrieval method is that the returned result set is large, the precision rate is relatively low, and the user still has to undertake a lot of information screening work. At the same time, the semantic connection contained in personal information is ignored.

Embodiment Construction

[0044] The present invention will be further described in detail below in conjunction with the drawings.

[0045] Reference figure 1 , A conceptual space navigation method based on conceptual association, which is applied to the application layer of the personal information management model. The personal information management model is used to complete a series of functions such as the organization, storage, management, and processing of personal information, including the resource layer, the conceptual space layer, and the application layer:

[0046] E1. The resource layer includes personal information stored in the DBMS, file system and other systems. Personal information in the file system includes text data and non-text data. Text data includes email, pdf files, office files, html files and other data, and non-text data includes video, audio, and picture data;

[0047] E2. The concept space layer uses a concept to point to a collection of information resources that are similar o...

Abstract

The concept space navigation method based on concept association includes the following steps: 1) The user selects a concept C as the initial concept for navigation; 2) Calculates the similarity between C and other concepts in the concept space, and updates the old value of the similarity (if Exist); 3) Obtain the semantic association information of C { <c，相关概念，关联类型>}; 4) Integrate and standardize the two indicators of the similarity value between each other concept and C, and the presence or absence of semantic association; 5) According to the two indicators in step 4), calculate the value of the degree of correlation between each other concept and C , and sort the top K concepts according to this value; 6) Visually present the K concepts and their similarity value with C and semantic association information with the concept map; 7) When the user finds the target concept, the navigation ends; or select the required To further expand (explore) the concept, repeat the above steps. The invention navigates from a designated concept to its associated concept group, which facilitates users to find target concepts and improves retrieval efficiency.< / c，相关概念，关联类型>

Description

Technical field [0001] The present invention relates to the organization and query and retrieval technology of personal information management, in particular to a concept diagram description form of a concept space and a concept navigation method based on concept association. Background technique [0002] Personal information management involves people's practice and research activities in order to obtain, organize, maintain and retrieve information for daily use, including methods and rules for personal information acquisition, mechanisms for organizing and storing information, and rules and procedures for maintaining the system , Retrieval mechanism. However, with the rapid development of modern information technology, the crisis caused by the information explosion has increasingly affected the management of personal information, which has brought huge difficulties to the maintenance and access of the required information. A large amount of information is piled up in the form ...
