(2) Higgs Twitter Dataset
希格斯（Higgs）数据集的建立是在2012年7月4日宣布发现具有希格斯玻色子玻色子特征的新粒子之前，之中和之后监视Twitter上的传播过程而建立的。和2012年7月7日。
此处提供的四个定向网络已从Twitter中的用户活动中提取为：
1. 转推（转推网络）
2. 回复（回复网络）现有推文
3. 提及（提及网络）其他用户
4. 参与上述活动的用户之间的朋友/追随者社交关系
5. 关于希格斯玻色子发现期间Twitter活动的信息
值得一提的是，用户ID已被匿名化，并且所有网络都使用相同的用户ID。这种选择允许将Higgs数据集用于有关大规模相互依存/互连的多路复用/多层网络的研究，其中一层负责社会结构，三层负责编码不同类型的用户动态。
此数据集最终更新于2015年3月31日更新。
