ABSTRACT
As the flood of information continues to grow, it becomes ever more necessary to extract just the portion of the flow which is of interest to each user. The Topic Detection and Tracking (TDT) project [1, 3, 6, 5] addressed and continues to address this need, but has been of necessity applied in a batch-processing context on a static collection. What is required for topic detection and tracking to be of utility to end-users is a real-time system which operates on a live stream of information. This paper describes the extension and modification of a batch-oriented tracking system into a real-time server for event detection, event tracking, document summarization, and translation.

Summarizing Event Opinions for News Reports
ICNISC '15: Proceedings of the 2015 International Conference on Network and Information Systems for Computers (ICNISC)Opinions on the news reports are very useful for people to understand an event, while the vast availability of such opinions becomes overwhelming to people when there is too much to digest. In this paper, we present an approach on summarizing event ...
Reader Comment Digest through Latent Event Facets and News Specificity
When a significant event occurs, many news articles from different newsagents often report it. Moreover, these newsagents also provide platforms for their readers to write comments expressing their views or understanding. Through digesting these reader ...
Use of place information for improved event tracking
Special issue: AIRS2005: Information retrieval research in AsiaThe main purpose of topic detection and tracking (TDT) is to detect, group, and organize newspaper articles reporting on the same event. Since an event is a reported occurrence at a specific time and place and the unavoidable consequences, TDT can ...
