Our aim for our participation in WebCLEF 2006 was to investigate the robustness of information retrieval techniques to crosslingual retrieval, such as compact document representations, and query reformulation techniques. Our focus was on the mixed monolingual task. Apart from the proper preprocessing and transformation of various encodings, we did not apply any language-specific techniques. Ins...

This year, the expert search task requires a list of support documents provided for each expert. The change implied that support documents for the potential experts should be found before getting the experts themselves, which is one of the natural ways for expert search. The two-stage ranking method we used last year was just following this way. We develop an expert experience model using windo...

This paper gives an overview of the work done at the University of Massachusetts, Amherst for the TREC 2006 Enterprise track. For the discussion search task, we compare two methods for incorporating thread evidence into the language models of email messages. For the expert finding task, we create implicit expert representations as mixtures of language models from associated documents.

Thoracic trauma is a common injury that has a high mortality rate. Fortunately, most can be treated by a simple maneuver as intercostal drainage (79.4%). During the decade 1997-2006, there were 897 admitted patients in the Trauma division of Siriraj Hospital. Most were men (85.5%) and the common age group was 21-30 years. Blunt trauma was the major type of injury (58.9%) and traffic accidents w...

In this paper we describe the planned setup of the INEX 2006 interactive track. As the track has been delayed and data collection has not been completed before the INEX 2006 workshop, the track will continue into 2007. Special emphasis is put on comparing XML element retrieval with passage retrieval, and on investigating differences between multiple dimensions of the search tasks.

This report describes the work done by the RFIA group at the Departamento de Sistemas Informáticos y Computación of the Universidad Politécnica of Valencia for the 2006 edition of the CLEF Question Answering task. We participated in three monolingual tasks: Spanish, Italian and French. The system used is a slightly revised version of the one we developed for the past year. The most interesting ...

For the 2006 edition of the Music Information Retrieval Evaluation eXchange (MIREX), we presented the latest enhancements to the aubio library, participating this year in four different tasks: Audio Melody Extraction, Audio Tempo Extraction, Audio Beat Tracking and Audio Onset Detection. The algorithms we submitted are tailored for causal operation and interactive systems. We describe here the ...

York University participated in the legal track this year. For this track, we developed an Okapi-based Legal Search Engine (LSE) v1.0. Our experiments mainly focused on evaluating the effect of a probabilistic text retrieval model on the legal domain. In order to address the special problems in legal text retrieval, new automatic feedback methods and term weighting methods are proposed and tested.

Spain has made major investments in tertiaryeducation...  Between 1995 and 2003, Spain has made major investments in tertiary education. Expenditure per student has increased by 43% which is the third highest increase in the OECD countries (OECD average of 6%). As the number of students in tertiary education has also increased by 11% during this period, overall expenditure has increased by 58%...

Since RoboCup 2004 we participate in both, the “classical” 2D-Simulation League as well as in the new 3D-competition. Last year, our team “AT Humboldt”, placed second at German Open while “AT Humboldt 3D” placed 8th at RoboCup World Championship in Osaka. For ten years we use our soccer agents as a research testbed for longterm deliberation and realtime reasoning, cooperation and coordination i...
