Atmospheric pollution is getting more and more attention because of the serious *** the pollutant source is one of the key steps to solve this *** paper introduces a new method to trace the pollution diffusion path according to the relevance of different areas where they were polluted(the relatively small areas regard as points or lattices in this paper).We present the single point tracing to show the specific traceability and the area tracing to show the pollution spread trend.
Hot events detection in text streams has drawn increasing attention in recent sequential data mining works. Different from traditional TDT task which find all the real events' cluster, hot events detection only id...

This report introduces the work of BUPT (PRIS) in Entity Track in TREC2009. The task and data are both new this year. In our work, an improved two-stage retrieval model is proposed according to the task. The first stage is document retrieval, in order to get the similarity of the query and documents. The second stage is to find the relationship between documents and entities. We also focus on entity extraction in the second stage and the final ranking.
In this paper, a language tagging template named POC-NLW (position of a character within an n-length word) is presented. Based on this template, a two-stage statistical model for Chinese word segmentation is construct...
