ego-Facebook

This dataset consists of 'circles' (or 'friends lists') from Facebook. Facebook data was collected from survey participants using this Facebook app. The dataset includes node features (profiles), circles, and ego networks.Facebook data has been anonymized by replacing the Facebook-internal ids for each user with a new value. Also, while feature vectors from this dataset have been provided, the interpretation of those features has been obscured. For instance, where the original dataset may have contained a feature "political=Democratic Party", the new data would simply contain "political=anonymized feature 1". Thus, using the anonymized data it is possible to determine whether two users have the same political affiliations, but not what their individual political affiliations represent.

本数据集收录来自脸书（Facebook）的“圈子”（或称“好友列表”）数据。脸书数据通过该脸书应用程序面向调研参与者采集所得。本数据集涵盖节点特征（用户个人资料）、圈子结构以及自我中心网络（ego network）。脸书数据已完成匿名化处理：将每位用户的脸书内部标识符替换为新的数值。此外，尽管本数据集提供了特征向量，但这些特征的具体语义已被遮蔽。例如，若原始数据集包含特征“政治倾向=民主党”，匿名化后的新数据将仅显示“政治倾向=匿名特征1”。因此，依托该匿名化数据集，仅可判别两位用户是否具有相同的政治倾向，却无法获知他们各自具体的政治倾向类别。

背景概述

ego-Facebook数据集包含匿名化的Facebook社交网络数据，涵盖用户的朋友列表、节点特征和自我网络。数据经过处理以保护隐私，特征的具体含义被模糊化，仅保留用户间特征的相似性信息。
