What’s Worthy of Comment? Content and Comment Volume in Political Blogs.
Summary
This Paper describes a topic model based approach in modeling the relationship between the text content of a political blog post and the comment volume (i.e. the total amount of response) that a post will receive.
Brief description of the method
The author's propose a generative model, called the Topic-Poisson model, which proceeds as follows. The number of topic is fixed in advance.
Experimental Result
Task: Predict whether a blog post will have higher volume than the average seen in training data (Note that they are NOT predicting the absolute number of words in the comments)
The authors use a subset of the Yano & Smith blog dataset; data from 2 blogs, Matthew Yglesias (denoted MY) and Red State (denoted RS) were used.
The compared models were:
- Naive Bayes
- Regression: linear regression with elastic net regularization
- Topic Poisson
- Topic Negative Binomial
- CommentLDA
