Using Blog Properties to Improve Retrieval
4 pages; PDF.

From the abstract:

This paper describes three simple heuristics which improve opinion retrieval effectiveness by using blog-specific properties. Blog timestamps are used to increase the retrieval scores of blog posts published near the time of a significant event related to a query; an inexpensive approach to comment amount estimation is used to identify the level of opinion expressed in a post; and query-specific weights are used to change the importance of spam filtering for different types of queries. Overall, these methods, combined with non-blogspecific retrieval approaches, result in substantial improvements over state-of-the-art.

This paper will be presented at the 2007 International Conference on Weblogs and Social Media.
The conference will take place next month in Boulder, CO.
