New in TREC-2001 was the Video Track, the goal of which was to promote progress in content-based retrieval from digital video via open, metrics-based evaluation. The track built on publicly available video provided by the Open Video Project of the University of North Carolina at Chapel Hill under Gary Marchionini (Marchionini, 2001), the NIST Digital Video Library (Over, 2001), and stock shot v...

This paper describes our entry into the TREC 2011 Web track. We extracted and ranked results from the ClueWeb09 corpus using a parallel processing pipeline that avoids the generation of an inverted file. We describe the components of the parallel architecture and the pipeline, how we ran the TREC experiments, and we present effectiveness results.

In this paper, we present our system called LADS, tailored to work on the TREC Entity Track Task of Related Entity Finding. The LADS system consists of four key components: document retrieval, entity extraction, feature extraction and entity ranking. We adopt the open advancement framework for the rapid development and use a learning-to-rank approach to rank candidate entities. We also experime...

We describe our participation in the TREC 2003 Question Answering, Robust, and Web tracks. We provide a detailed account of the ideas underlying our approaches to these tasks, report on our results, and give a summary of our findings so far.

We present a system to identify abbreviation expansion pairs from scientific articles. We work with the Genomics track of the TREC collection. Authors report abbreviations in two places an abbreviations section and within the body of a scientific article. Articles with an abbreviations section had fewer abbreviations than those that did not have an abbreviations section (an average of 7.1 versu...

In this paper, we present a set of experiments towards a cross-language Greek-English Question-Answering (QA) system. After exploring previous work done both in monolingual and cross-lingual QA, we have applied the common “question reformulation” strategy used in monolingual systems along with different translation strategies and evaluated the results with the TREC question set. We have mainly ...

CONTEXT A newborn blood screening (NBS) test that could identify infants with a profound deficiency of T cells may result in a reduction in mortality. OBJECTIVE To determine if quantitating T-cell receptor excision circles (TRECs) using real-time quantitative polymerase chain reaction on DNA extracted from dried blood spots on NBS cards can detect infants with T-cell lymphopenia in a statewid...
