Algorithms

Good afternoon!
Please tell me information sources on the topic "Topic Detection and Tracking": sites, links, publications.
Also, I can't find publications:
• Huizhen Wang, Jingbo Zhu, Duo ji, Na Ye and Bin Zhang, (2005), “Time Adaptive Boosting Model for Topic Tracking”, Proceeding of NLP-KE'05,IEEE
• Wei Wang , JunZheng, Wu Yang and Yongtian Yang, (2008), “A Dual Center Event Description Model Used in Event Tracking”, 2009 World Congress on Computer Science and Information Engineering,IEEE
• Wang Xiaowei, JiangLongbin, MaJialin, Jiangyan, (2008) , “Use of NER Information for Improved Topic Tracking”, Eighth International Conference on Intelligent Systems Design and Applications, IEEE
Does anyone have or have access to them?
