Abstract: A framework based on event detection is proposed to do popular comments prediction in news Apps. Taking advantage of the aggregation of news Apps, the problem of sparse data for a single news App is avoided. Also, in this framework, events are detected as the context of comments to solve the cold-start problem; components are loosely coupled, which means it can adapt all kinds of granularity of events. We provide an instance of this framework and it turns out that using the event detection strategy mentioned above, the sparse data problem no longer exists. Whats more, the framework brings a better prediction result than using the comment itself.

Key words: hot comment, prediction, event, news App
