Faceted Blog Distillation System: Find an in-Depth Blog

With the increasing of blog users, the traditional blog search can no longer meet their demands. More work should be done to accommodate the need of finding good blogs to read, besides the topicrelevant blogs. This paper focuses on the problem of an in-depth faceted blog distillation for addressing the quality aspect of the retrieval blogs. We propose a novel L-Qtf coefficient and LQE model to help finding an in-depth blog. Our in-depth blog distillation system achieved the best MAP performance in the TREC Blog track 2009. In this paper, we improve the prior system with L-Qtf coefficient and the results show its effectiveness.
