Novelty Detection: The TREC Experience
- In HLT/EMNLP
, 2005
"... A challenge for search systems is to detect not only when an item is relevant to the user’s information need, but also when it contains something new which the user has not seen before. In the TREC novelty track, the task was to highlight sentences containing relevant and new information in a short, ..."

The TREC Experiments and their Impact on Europe
- Journal of Information Science
, 1997
"... : Information retrieval (IR) research on text collections has concentrated on improving the effectiveness of the indexing and retrieval operations. For the most part, the evaluation of IR systems has been carried out on relatively small collections of documents, queries and relevance assessments. I ..."

. In 1992 the first of a series of evaluation exercises called TREC (Text REtrieval Conference) was launched in the US and these exercises have continued annually since then. What makes TREC notable in IR research is that the document collections used are huge compared to previous ones and the groups
The Lowlands' TREC Experiments 2005

, 2006
"... This paper describes our participation to the TREC HARD track (High Accuracy Retrieval of Documents) and the TREC Enterprise track. The main goal of our HARD participation is the development and evaluation of so-called query profiles: Short summaries of the retrieved results that enable the user to ..."

Time-Based Language Models
, 2003
"... We explore the relationship between time and relevance using TREC ad-hoc queries. A type of query is identified that favors very recent documents. We propose a time-based language model approach to retrieval for these queries. We show how time can be incorporated into both query-likelihood models an ..."

Query expansion using lexical-semantic relations
- In Proceedings of the 17th Annual International ACM SIGIR Conference on Research and Development in Information Retrieval
, 1994
"... Applications such as office automation, news filtering, help facilities in complex systems, and the like require the ability to retrieve documents from full-text databases where vocabulary problems can be particularly severe. Experiments performed on small collections with single-domain thesauri sug ..."

A Probabilistic Model of Information Retrieval: Development and Status
, 1998
"... The paper combines a comprehensive account of the probabilistic model of retrieval with new systematic experiments on TREC Programme material. It presents the model from its foundations through its logical development to cover more aspects of retrieval data and a wider range of system functions. Eac ..."

Information Retrieval as Statistical Translation
