Topic Tracking in a News Stream
In this paper we describe a Topic Tracking system based on unigram models, submitted by Dragon Systems in the December 1998 Topic Detection and Tracking (TDT) Evaluation. We focus on the most recent developments, including improvements in the smoothing of sparse unigram models, a better discriminator, and the implementation of unsupervised adaptation. We give results on the default test conditi...
متن کاملEmerging Topic Tracking System
We designed a system that track the changes to a particular area of user’s interests on the Web and generate a summary of emerging topic back to the user. This system consists of three main components, which are Area View System, Web Spider and Summary Generator. Area View System as a Meta-search engine will direct the user keyword to a commercial search engine, get the hits, do further analysi...
متن کاملProbabilistic models for topic detection and tracking
We present probabilistic models for use in detecting and tracking topics in broadcast news stories. Our information retrieval (IR) models are formally explained. The Topic Detection and Tracking (TDT) initiative is discussed. The application of probabilistic models to the topic detection and tracking tasks is developed, and enhancements are discussed. We discuss four variations of these models,...
متن کاملEmerging topic tracking system in WWW
Due to its open characteristic, the Web is being posted with vast amount of new information changes continuously. Consequently, at any time, it is conceivable that there will be hot issues (emerging topics) being discussed in any information area on the Web. However, it is not practical for the user to browse the Web manually all the time for the changes. Thus, we need this Emerging Topic Track...
متن کاملA Probabilistic Method for Tracking a Vocalist
When a musician gives a recital or concert, the music performed generally includes accompaniment. To render a good performance, the soloist and the accompanist must know the musical score and must follow the other musician's performance. Both performing and rehearsing are limited by constraints on the time and money available for bringing musicians together. Computer systems that automatically ...
