Discriminative models of integrating document evidence and document-candidate associations for expert search

Yi Fang, Luo Si, Aditya P. Mathur
2010 Proceeding of the 33rd international ACM SIGIR conference on Research and development in information retrieval - SIGIR '10  
An extensive set of experiments have been conducted on two TREC Enterprise track corpora (i.e., W3C and CERC) to demonstrate the effectiveness and robustness of the proposed framework.  ...  On the other hand, discriminative models have received little attention in expert search research, although they have been shown to outperform generative models in many other information retrieval and  ...  This research was partially supported by a grant from the Indiana Economic Development Company, the NSF research grant IIS-0749462, and a grant from Purdue University.  ...
