METHOD, APPARATUS, AND SYSTEM FOR DETERMINING DEGREE OF ASSOCIATION OF INPUT AND OUTPUT OF BLACK BOX SYSTEM

摘要

A method, an apparatus, and a system for determining the degree of association of the input and output of a black box system, the method comprising: matching service quality indicator KQI data in the black box system with key performance indicator KPI data to form a data vector space; on the basis of the service type of the KQI data, clustering the KPI data; breaking down the data vector space to separate out association features of the KPI data to the KQI data, and calculating a normalised degree of association of the KPI data to the KQI data; on the basis of the normalised degree of association, respectively determining KPI data associated with each KQI data, and calculating an association weighting of the associated KPI to the KQI data; and determining that the associated KPI data and association weighting are the degree of association of the input and output of the black box system. The present invention solves the problems in the prior art of low precision and finding incomplete items of association when determining the degree of association of the input and output of a black box system.
