Problems solved by technology

[0005] The technical problem to be solved by the present invention is that the judgment of the relationship strength of knowledge points in the prior art lacks an absolute measurable value, the measurement of the relationship strength is not accurate enough, and some stronger relationship strengths cannot be found. Measure knowledge from the global space The relationship strength of points, using the absolutely measurable value of the relationship strength of knowledge points, provides a method and system for measuring the relationship strength of knowledge points

Embodiment 1

[0098] This embodiment provides a flow chart of a method for measuring the relationship strength of knowledge points as shown in figure 1 As shown, the knowledge point described in this embodiment is a kind of knowledge interaction unit, which represents a concept or an entity, such as Qin Shihuang, Tang Dynasty, and Reform Movement of 1898. In this embodiment, the names of knowledge points and related texts of knowledge points are shown in Table 1. There are three knowledge points in total. For the convenience of description, the names are recorded as A, B, and C respectively. N is a piece of text, which does not contain knowledge point name A, B or C.

[0100] Knowledge roll call

[0101] The method for measuring the relationship strength of the knowledge points includes the following steps:

[0102] S1: Calculate the explicit relationship strength of all knowledge points, and generate...

Embodiment 2

[0156] In this embodiment, except that step S3 is different from that in embodiment 1, other steps are the same as in embodiment 1. S3: calculate the implicit relationship strength of domain knowledge points according to the weighted directed graph G, and generate the implicit relationship strength of domain knowledge points. Relationship Strength Matrix I.

[0157] The calculation method of the implicit relationship strength of the domain knowledge points is:

[0158] f I (i,j)=exp(-C ij )

[0159] Among them, f I (i, j) represents the knowledge point o i to knowledge point o j The implicit relationship of C ij Represents the knowledge point o in the weighted directed graph G i to knowledge point o j The shortest simple path length; if the knowledge point o i to knowledge point o j There is no simple path, then f I (i, j) is equal to zero; the implicit relationship strength between the knowledge point and itself is set to zero; the implicit relationship strength f ...

Embodiment 3

[0162] In this embodiment, except that step S3 is different from that in embodiment 1, other steps are the same as in embodiment 1. S3: calculate the implicit relationship strength of domain knowledge points according to the weighted directed graph G, and generate the implicit relationship strength of domain knowledge points. Relationship Strength Matrix I.

[0163] The calculation method of the implicit relationship strength of the domain knowledge points is:

[0164] f I (i,j)=exp(-C ij )

[0165] Among them, f I (i, j) represents the knowledge point o i to knowledge point o j The implicit relationship of C ij Represents the knowledge point o in the weighted directed graph G i to knowledge point o j The shortest simple path length; if the knowledge point o i to knowledge point o j There is no simple path, then f I (i, j) is equal to zero; the implicit relationship strength between the knowledge point and itself is set to zero; the implicit relationship strength f ...

Abstract

The invention provides a method and system for measuring knowledge point relationship strength. The method comprises the steps that firstly, the overt relationship strength of all knowledge points is worked out, and a knowledge point relationship strength matrix is generated; secondly, according to the relationship strength matrix of all the knowledge points, a weighted digraph is constructed; thirdly, according to the weighted digraph, the covert relationship strength of the knowledge points is worked out according to the weighted digraph, and a knowledge point covert relationship strength matrix is generated; traversal is conducted on the covert relationship strength matrix, and the knowledge point relationship strength matrix is updated. By the adoption of the method for measuring knowledge point relationship strength, the problems that in the prior art, when knowledge point relationship strength is judged, an absolute measurable value is not available, the measurement of relationship strength is not accurate, and a part of stronger relationships are not found are solved.

Description

technical field [0001] The invention relates to a method and system for measuring the relationship strength of knowledge points, belonging to the technical field of electrical digital data processing. Background technique [0002] With the advent of the era of knowledge economy, digital publishing has become an inevitable trend in the development of the publishing industry, and people have shifted from paper reading to electronic reading in large numbers. Diverse publishing resources such as e-books, periodicals, and digital newspapers contain a large amount of authoritative knowledge and have high application value. These digital publishing resources organize and disseminate knowledge and information in the form of documents and chapters such as books or periodicals in large quantities. What people hope to obtain is not the documents themselves, but the relevant knowledge points in the documents directly, that is, all relevant knowledge points in this field can be Precise ...
