Kevyn Collins-Thompson, Jamie Callan, Egidio Terra, Charles L.A. Clarke
2004 Proceedings of the 27th annual international conference on Research and development in information retrieval - SIGIR '04  
Acknowledgments This work was part of the NRRC RIA summer workshop.  ...  We evaluate two QA systems using TREC 2002 test set questions [9] : Carnegie Mellon's JAVELIN system [7] and Waterloo's Mul-tiText QA system [2] .  ...  In the first experiment, 445 questions of the TREC 2002 QA track (those with answers in the AQUAINT collection) were given as input to each of five retrieval systems, as shown in Table 1 .  ...

Component-Based Evaluation for Question Answering [chapter]

Teruko Mitamura, Eric Nyberg
2020 Evaluating Information Retrieval and Access Tasks  
This chapter describes the component-based evaluation of automatic question answering (QA) systems, which was pioneered in the NTCIR-7 ACLIA challenge and has became a fundamental part of QA system development  ...  We summarize the history of component evaluation for QA and describe more recent work at Carnegie Mellon (on TREC Genomics, BioASQ, and LiveQA datasets) which has descended directly from our experiences  ...  Special thanks go to Hideki Shima, who worked on CMU's Javelin QA system to develop the component-based evaluation and helped to organize the ACLIA tasks.  ...

Towards Logical Inference for Arabic Question-Answering

Wided Bakari, Patrice Bellot, Omar Trigui, Mahmoud Neji
2015 Research in Computing Science  
This article constitutes an opening to think of the modeling and the analysis of Arabic texts within a question-answering system.  ...  Now, our work is concentrated on an implementation step to develop a question-answering system in Arabic using the techniques of textual entailment recognition.  ...  Marsha, question-answering system, relies on the same techniques used in English systems developed from TREC (Li and Croft, 2001) . Marsha focused on a method based on the TREC question-answering.  ...

The TREC question answering track

ELLEN M. VOORHEES
2001 Natural Language Engineering  
The TREC 2003 question answering track contained two tasks, the passages task and the main task.  ...  In the passages task, systems returned a single text snippet in response to factoid questions; the evaluation metric was the number of snippets that contained a correct answer.  ...  Acknowledgements My thanks to Chris Buckley for fitting the error rate curves shown in Figures 5 and 6 .  ...

Question Answering in Restricted Domains: An Overview

Diego Mollá, José Luis Vicedo
2007 Computational Linguistics  
Currently we are witnessing a surge of activity in the area from the perspective of IR, initiated by the Question Answering track of TREC 1 in 1999 (Voorhees 2001).  ...  A QA system that finds specific answers to a user's question based on such documentation would be very useful.  ...  Still, for the purposes of this article, WordNet is an ontology. This view is supported by its use in many systems, including open-domain question answering systems (Moldovan and Novischi 2002) .  ...

Linguistic and semantic passage retrieval strategies for question answering

Matthew W. Bilotti
2011 SIGIR Forum  
Through question analysis, the QA system has compiled a sophisticated information need representation for what constitutes an answer to the question.  ...  Question Answering (QA) is the task of searching a large text collection for specific answers to questions posed in natural language.  ...  This test collection consists of 109 factoids, or factual, short-answer questions, drawn from the TREC 2002 QA track main task.  ...
