Abstract
The present invention provides a method and system of measuring knowledge point relationship strength, the method comprising calculating explicit relationship strength for all knowledge points and generating a knowledge point relationship strength matrix M; constructing a weighted and directed graph G according to the knowledge point relationship strength matrix of all knowledge points; calculating knowledge point implicit relationship strength values according to the weighted and directed graph and generating a knowledge point implicit relationship strength matrix I; traversing the knowledge point implicit relationship strength matrix I and updating the knowledge point relationship strength matrix M. The above technical solution may effectively avoid the problem of lack of an absolute measurable value for the determination of relationship strength, incorrect measurement of relationship strength, or unable to discover some stronger relationship strength in the prior art.
