An information-pattern-based approach to novelty detection

Li, Xiaoyan - Personal Name; Croft, W. Bruce - Personal Name;

In this paper, a new novelty detection approach based on the identification of sentence level information patterns
is proposed. First, “novelty” is redefined based on the proposed information patterns, and several different types
of information patterns are given corresponding to different types of users’ information needs.
Second, a thorough analysis of sentence level information patterns is elaborated using data from the TREC novelty tracks, including sentence lengths, named entities (NEs), and sentence level opinion patterns. Finally, a unified information-pattern-based approach to novelty detection (ip-BAND) is presented for both specific NE topics and more general topics. Experiments on novelty detection on data from the TREC 2002, 2003 and 2004 novelty tracks show that the proposed approach significantly improves the performance of novelty detection in terms of precision at top ranks. Future research directions are suggested.

About Us

Established in 2003, the Library of Kemitraan was originally designed to record and collect all Kemitraan and grantees publications. However, today it broadly develops and serves more sectors to expand the collection to facilitate research activities, particularly since the inception of the Knowledge and Research Management within Kemitraan.
