Method and system for measuring knowledge point relation strength

摘要

To provide a method and a system for measuring knowledge point relation strength.The method includes the steps of calculating a knowledge point explicit relationship strength value for all knowledge points and generating a knowledge point relation strength matrix M and a weighted directed graph according to a knowledge point relation strength matrix of all knowledge points Generating a knowledge point implicit relation strength value according to a weighted directed graph G and generating a knowledge point implicit relation strength matrix I and traversing the knowledge point implicit relation strength matrix I And updating the knowledge point relation strength matrix M. The technical solution described above has the problem of lack of an absolutely measurable value for the determination of the relationship strength of the prior art, inaccurate measurement of the relationship strength or inability to discover some strong relationship strength Can be effectively avoided.BACKGROUND OF THE INVENTION
