作者：

Highlights：

• We compare bot & normal user tweets and check their up-to-dateness by using RSS feeds.

• We evaluate the relevance of tweet contents to the categorical taxonomies of users.

• Longer tweets of bot users reflect their categories better than normal users.

• Referring to RSS news feeds, content provided by bot users is more up-to-date.
