APPARATUS AND METHOD FOR EXECUTING AN AUTOMATED ANALYSIS OF DATA, IN PARTICULAR SOCIAL MEDIA DATA, FOR PRODUCT FAILURE DETECTION

摘要

An apparatus and a method for executing an automated analysis of analysis input data (e.g. social media data and/or On-Board-Diagnosis data) for product failure detection is proposed. Data analysis processing is performed, including: word count processing to determine word count numbers indicative of occurrence frequencies for keywords of a database in user-created text documents of the social media data; correlation determination processing to determine, for each of a plurality of keyword pairs, a respective correlation coefficient; correlation-link identification processing to identify correlation-linked keyword pairs for which the determined correlation coefficient exceeds a correlation threshold; and correlation group identification processing to identify correlation groups of keywords based on the identified correlation-linked keyword pairs; and, if one or more correlation groups of keywords are identified, analysis result data indicative of at least one of the one or more identified correlation groups of keywords is output.
