北京市微博影响力指数数据

作为社交媒体平台，微博已经成为热点事件和网络舆情的重要策源地，科学准确评估微博的影响力对于明晰微博信息传播特点，深入挖掘微博传播潜力，进一步规范和指导微博平台的传播行为具有较大的理论和实践意义。但单纯地通过转发量、评论量等数据对微博影响力进行分析过于片面，因此系统通过微博影响力指数这个统一的数据指标来评定北京市微博所发稿件在微博用户的传播影响力，为评估北京市微博影响力、深入挖掘微博传播力提供数据参考。微博影响力指数通过微博的活跃度和传播度来反映账号的传播能力和传播效果
指标体系:
采用数据：发博数、转发数、评论数、点赞数。
采用指标：主要通过活跃度W1和传播度W2两大维度来进行评价。
影响力计算：
BCI（影响力指数）=（20% × W1 +80% × W2 ）× 160
W1（活跃度） = ln（发博数 +1）
W2（传播度）=40% × ln（转发数 +1）+ 40% × ln（ 评论数+1）+ 20% × ln（点赞 +1）
BCI数据越高，说明该账号传播影响力越大，反之则影响力越小

As a social media platform, Weibo has become an important source of hotspot events and online public opinion. Scientific and accurate assessment of Weibo's influence is of great theoretical and practical significance for clarifying the characteristics of Weibo's information dissemination, deeply exploring its dissemination potential, and further standardizing and guiding the dissemination behaviors on the Weibo platform.

However, analyzing Weibo's influence solely based on data such as forward counts and comment counts is overly one-sided. Therefore, this system uses the Weibo Influence Index as a unified data metric to evaluate the dissemination influence of posts published by Weibo accounts in Beijing among Weibo users, providing data references for assessing the influence of Beijing-based Weibo accounts and deeply exploring their dissemination capabilities. The Weibo Influence Index reflects an account's dissemination capacity and effect through its activity level and dissemination degree.

Indicator System:
Collected Data: Number of published posts, number of forwards, number of comments, number of likes.
Evaluation Indicators: The evaluation is mainly conducted through two dimensions: Activity Level (W1) and Dissemination Degree (W2).

Influence Calculation:
BCI (Influence Index) = (20% × W1 + 80% × W2) × 160
W1 (Activity Level) = ln(Number of published posts + 1)
W2 (Dissemination Degree) = 40% × ln(Number of forwards + 1) + 40% × ln(Number of comments + 1) + 20% × ln(Number of likes + 1)

A higher BCI value indicates greater dissemination influence of the corresponding account, while a lower BCI value signifies weaker influence, and vice versa.
