Experiments with the Eurospider Retrieval System for CLEF 2000 [chapter]

Martin Braschler, Peter Scháuble
2001 Lecture Notes in Computer Science  
This paper describes the experiment setup that we used for our CLEF participation and gives a preliminary analysis of the results that were obtained.  ...  We participated in the multilingual and monolingual tasks with three runs each. For our experiments, we investigated query translation using different approaches, as well as document translation.  ...  Additional thanks go to Patrick Frey for tuning the rules of the German stemmer and Min-Yen Kan for a lot of scripts originally written for last year's TREC that proved a big help in doing these experiments  ...

Eurospider at CLEF 2002 [chapter]

Martin Braschler, Anne Göhring, Peter Schäuble
2003 Lecture Notes in Computer Science  
For the CLEF 2002 campaign, Eurospider participated in the multilingual and German monolingual tasks. Our main focus was on trying new merging strategies for our multilingual experiments.  ...  In this paper, we describe the setup of our system, the characteristics of our experiments, and give a first analysis of some of the results.  ...  Acknowledgements We thank Jacques Savoy from Université de Neuchâtel for providing us with his runs that we used for merging in the experiment labeled "EAN2MDF4".  ...

Combination Approaches for Multilingual Text Retrieval

Martin Braschler
2004 Information retrieval (Boston)  
We describe the Eurospider component for Cross-Language Information Retrieval (CLIR) that has been employed for experiments at all three CLEF campaigns to date.  ...  The central aspect of our efforts is the use of combination approaches, effectively combining multiple language pairs, translation resources and translation methods into one multilingual retrieval system  ...  Acknowledgments Peter Schäuble, Bärbel Ripplinger and Anne Göhring were involved in planning and conducting the Eurospider participation in the three CLEF campaigns.  ...

Cross-Language Evaluation Forum: Objectives, Results, Achievements

Martin Braschler, Carol Peters
2004 Information retrieval (Boston)  
We also make proposals for future directions in system evaluation aimed at meeting emerging needs.  ...  We summarize the main lessons learned during this period, outline the state-of-the-art of the research reported in the CLEF experiments and discuss the contribution that this initiative has made to research  ...  CLEF is an activity conducted by the CLEF project consortium, of which the two authors are but two members.  ...

How Effective is Stemming and Decompounding for German Text Retrieval?

Martin Braschler, Bärbel Ripplinger
2004 Information retrieval (Boston)  
Information retrieval systems operating on free text face difficulties when word forms used in the query and documents do not match.  ...  We report on our experiments on stemming for German, where an additional issue is the handling of compounds, which are formed by concatenating several words.  ...  Thanks go to John Goldsmith for providing the Linguistica software, and the CLEF consortium and its data providers for the construction of the test collection.  ...

Workshop on Novel Methodologies for Evaluation in Information Retrieval [chapter]

Mark Sanderson, Martin Braschler, Nicola Ferro, Julio Gonzalo
Lecture Notes in Computer Science  
With such challenges in mind that we decided to hold the first Workshop on Novel Methodologies for Evaluation in Information Retrieval.  ...  Information retrieval is an empirical science; the field cannot move forward unless there are means of evaluating the innovations devised by researchers.  ...  We provide a motivation for the new task, a framework for its evaluation together with preliminary experiments, and some possible approaches that a system can adopt for performing the task.  ...
