Association credibility evaluation method and device based on activity index

The invention discloses an association credibility evaluation method and device based on an activity index. The association credibility evaluation method comprises the steps of S1, selecting and obtaining element space-time distribution detail information in a fixed time range; S2, obtaining a plurality of association activity through a time slice association analysis method based on the element space-time distribution detail information; S3, evaluating the plurality of association activity to obtain an activity index; and S4, evaluating the association credibility based on the activity index. 本发明公开了一种基于活跃度指标的关联可信度评估方法及装置，关联可信度评估方法包括：步骤S1：选取并获得固定时间范围内的要素时空分布明细信息；步骤S2：基于要素时空分布明细信息通过时间片关联分析方法获得多个关联活跃度；步骤S3：对多个关联活跃度进行评估获得活跃度指标；步骤S4：基于所述活跃度指标进行关联可信度的评估。
