METHOD AND SYSTEM FOR OBTAINING A KNOWLEDGE POINT IMPLICIT RELATIONSHIP

摘要

The present invention provides a method and system for obtaining a knowledge point implicit relationship; first, establishing a knowledge point explicit relationship map according to knowledge point explicit relationship strengths; second, computing according to said knowledge point explicit relationship map a simple path set of two knowledge points; then, computing the implicit relationship strength values corresponding to each simple path in said simple path set; further, comparing the relationship strength values of the simple paths and setting as the siginificant implicit relationship strength value the simple path relationship strength having the largest value also greater than a preset threshold value. The described solution effectively avoids the problems in the prior art of only using the relationship strengths between knowledge points and the ratio of relationship strengths to obtain the implicit relationship of knowledge points, the manner of searching for an implicit relationship being insufficiently accurate, and also not performing normalization processing on the relationship strengths, resulting in a lack of absolute measurable value for determination of relationship strength and making it difficult to obtain a most representative implicit relationship.
