Jinfeng Yang, Xishuang Dong, Yi Guan, Chengzhen Huang, Sheng Wang · 2010
This paper describes our participation in the faceted blog distillation task at Blog Track 2010. In our approach, indri toolkit is applied for basic topic relevance retrieval. Then the Maximum Entropy (ME) model is adopted to judge the relevance of each blog to specified facet. Feed faceted relevance is calculated by integrating the average relevance of all blogs within a feed and the average relevance of the most relevant N blogs. Two implementations are applied to calculate feed faceted relevance. Experimental results on Blogs08 dataset show the effectiveness of our approach. 1
