    • 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.
    • 为产品的故障检测的装置和用于执行关于分析的输入数据的自动分析的方法(例如,社交媒体数据和/或车载诊断数据)被提议。 数据分析处理被执行,其中包括:字计数处理,以指示发生频率在社交媒体数据的用户创建的文本文档的数据库的关键字确定性矿wordcount的数字; 相关性确定处理,以确定矿,每个关键字对,一个respectivement相关系数的多个; 相关性的链路识别处理以识别相关联的关键字对的量,确定开采相关系数超过相关性阈值; 和相关的组识别处理以识别基于所识别的相关联的关键字对关键字的相关性基团; 并且,如果关键字的一个或多个相关组被鉴定,指示关键字的一个或多个识别的相关性基团中的至少一个的分析结果的数据被输出。

    • Provided is a monitoring system including an operation results acquisition unit that acquires time series data of each of a plurality of indexes that indicate operation results of a monitoring target; an overall index generation unit that produces time series data of an overall index by combining a plurality of index values at a same time point based on the time series data of each of the plurality of indexes; and a change point detection unit that analyzes the time series data of the overall index, and detects a point where a significant change appears in the overall index values, as a change point in a status of the monitoring target.
    • 提供一种监视系统,其包括:操作结果获取单元,其获取指示监视目标的操作结果的多个索引中的每一个的时间序列数据; 综合索引生成单元,其基于多个索引中的每一个的时间序列数据,通过组合同一时间点处的多个索引值来生成整体索引的时间序列数据; 以及变化点检测单元,该变化点检测单元分析整体指标的时间序列数据,并且检测整体指标值中出现显着变化的点作为监测目标的状态中的变化点。
