Abstract
This poster aims to understand the unintentional collective actions of creating a knowledge structure by a large amount of users in forming Zhihu’s topic hierarchy. We analyzed 80,927 topic-editing logs of 10,055 topics under the top-level topic “discipline”. The results show that: 1) there are 17 levels of hierarchical relationships ,in which levels 5-9 receives the most activity in general; 2) user edits follow a power-law distribution, which implies only a few users play a key role in creating topic structure; 3) there are more concept edits at the beginning and more relationship edits as the structure develops; 4) Most of the topic relationships (68.1%) of Zhihu structure haven’t been questioned or revised but once they were questioned, they were mostly likely to be removed from the topic structure. These results provide the first insights into the social participation in creating of a hierarchical taxonomy from topic tags.
