Abstract: Topic tracking aims at tracking stories on known topic from the information stream of news media. In the vector space model based on classification algorithm, tracking algorithm is proposed based on updated topic and it is evaluated through experiments.
Key words: topic detection, topic tracking, vector space model, K-Nearest Neighbor(KNN)
