This paper describes the Question Answering for Machine Reading (QA4MRE) task at the 2012 Cross Language Evaluation Forum. In the main task, systems answered multiple-choice questions on documents concerned with four different topics. There were also two pilot tasks, Processing Modality and Negation for Machine Reading, and Machine Reading on Biomedical(More)
The Answer Validation Exercise at the Cross Language Evaluation Forum is aimed at developing systems able to decide whether the answer of a Question Answering system is correct or not. We present here the exercise description, the changes in the evaluation methodology with respect to the first edition, and the results of this second edition (AVE 2007). The(More)
This paper describes the first round of ResPubliQA, a Question Answering (QA) evaluation task over European legislation, proposed at the Cross Language Evaluation Forum (CLEF) 2009. The exercise consists of extracting a relevant paragraph of text that satisfies completely the information need expressed by a natural language question. The general goals of(More)

This paper describes the Question Answering for Machine Reading (QA4MRE) Main Task at the 2013 Cross Language Evaluation Forum. In the main task, systems answered multiple-choice questions on documents concerned with four different topics. There were also two pilot tasks, Machine Reading on Biomedical Texts about Alzheimer's disease, and Japanese Entrance(More)
This paper describes the baselines proposed for the ResPubliQA task. These baselines are purely based on information retrieval techniques. The selection of an adequate retrieval model that fit the specific characteristic of the supplied data is considered as a core part of the task. Applying a not adequate retrieval function would return a subset of(More)
Although much work on relation extraction has aimed at obtaining static facts, many of the target relations are actually fluents, as their validity is naturally anchored to a certain time period. This paper proposes a methodological approach to temporally anchored relation extraction. Our proposal performs distant supervised learning to extract a set of(More)
The paper offers an overview of the key issues raised during the seven years’ activity of the Multilingual Question Answering Track at the Cross Language Evaluation Forum (CLEF). The general aim of the Multilingual Question Answering Track has been to test both monolingual and cross-language Question Answering (QA) systems that process queries and documents(More)
This paper describes the second round of ResPubliQA, a Question Answering (QA) evaluation task over European legislation, a LAB of CLEF 2010. Two tasks have been proposed this year: Paragraph Selection (PS) and Answer Selection (AS). The PS task consisted of extracting a relevant paragraph of text that satisfies completely the information need expressed by(More)
