Paper Abstract:
|
The many-to-many social communication activity on the popular technology-news website Slashdot has
been studied. We have concentrated on the dynamics of message production without considering semantic
relations and have found regular temporal patterns in the reaction time of the community to a news-post as
well as in single user behavior. The statistics of these activities follow log-normal distributions. Daily and
weekly oscillatory cycles, which cause slight variations of this simple behavior, are identified. A superposition
of two log-normal distributions can account for these variations. The findings are remarkable since
the distribution of the number of comments per users, which is also analyzed, indicates a great amount of
heterogeneity in the community. The reader may find surprising that only a few parameters allow a detailed
description, or even prediction, of social many-to-many information exchange in this kind of popular
public spaces. |
