Compare Hassan et al, ICWSM 2009 and Document representation and query expansion models for blog recommendation

Papers

Ahmed Hassan, Dragomir R. Radev, Junghoo Cho, Amruta Joshi. 2009. Content Based Recommendation and Summarization in the Blogosphere. The International Conference on Weblogs and Social Media (ICWSM 2009). J. Arguello, J. L. Elsas, J. Callan, and J. G. Carbonell. Document representation and query expansion models for blog recommendation. In Proc. of the 2nd Intl. Conf. on Weblogs and Social Media (ICWSM), 2008.

Problem

Hassan et al. were trying to target the problem of ranking documents in a set based on their similarity to identify the representative blogs in a given set usually based on different topics, similar to blog summarization.

Arguello et al. were trying to target the problem of blog retrieval - retrieving ranked list of blogs relevant to the given user query.

Basically these two papers are trying to achieve different goals. Hassan et al. proposed methods of ranking blogs within a given topic collection. This ranking of blogs based on their importance in a topic collection can be useful for blog search tasks. Arguello et al. experimented with various models to try and improve the blog search results.

Big Idea

The two papers differ in their respective central ideas as they both try to solve different problems as mentioned in Problem section above. They do use a common data set to evaluate their experiments, but their results can't be compared due to the difference in the problem they are addressing.

Dataset Used

Hassan et al. used the TREC BLOG06 and UCLA Blogocenter datasets for experiments, whereas Arguello et al. used only the TREC BLOG06 dataset for its experiments.
