HIT_LTRC at TREC 2010 Blog Track: Faceted Blog Distillation

Jinfeng Yang, Xishuang Dong, Yi Guan, Chengzhen Huang, Sheng Wang
2010 Text Retrieval Conference  
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.  ...  Then the Maximum Entropy (ME) model is adopted to judge the relevance of each blog to specified facet.  ...  Faceted Blog Distillation The basic idea of this stage was adopting the Maximum Entropy model to predict a blog's inclination on a specified facet, and then calculating the faceted relevance in feed level  ...

RMIT at TREC 2010 Blog Track: Faceted Blog Distillation Task

Zhixin Zhou, Xiuzhen Zhang, Phil Vines
2010 Text Retrieval Conference  
For the baseline task, we adopted the BM25 model implemented in the Zettair search engine to establish a retrieval system of blog posts based on topic relevance.  ...  Similarly, for the faceted distillation task we built a system at the post level first. After that, scores are aggregated for blogs to re-rank the most relevant blogs for the facet inclinations.  ...  Following these intuitions, we proposed a two-step approach. With this approach, blogs are retrieved through two stages.  ...
