Multilingual Retrieval Experiments with MIMOR at the University of Hildesheim [chapter]

René Hackl, Ralph Kölle, Thomas Mandl, Alexandra Ploedt, Jan-Hendrik Scheufen, Christa Womser-Hacker
2004 Lecture Notes in Computer Science  
In this year's CLEF campaign we applied these strategies to multilingual retrieval with four languages. Our fusion experiments were carried out using freely available software.  ...  We used the snowball stemmers, internet translation services and Lucene's and the new MySQL's text retrieval tools.  ...  Furthermore, we acknowledge the work of several students from the University of Hildesheim who implemented MIMOR as part of their course work.  ...

Mono- and Crosslingual Retrieval Experiments at the University of Hildesheim [chapter]

René Hackl, Thomas Mandl, Christa Womser-Hacker
2005 Lecture Notes in Computer Science  
We used mainly the system Lucene and experimented with some of the most effective optimization strategies applied in CLEF.  ...  In this year's participation we continued to evaluate open source information retrieval software.  ...  Furthermore, we acknowledge the work of several students from the University of Hildesheim who implemented MIMOR as part of their course work.  ...

An Information Retrieval Prototype for Research and Teaching

Christa Womser-Hacker
2020 Zenodo  
This paper reports on MIMOR which was modelled as an open meta infor-mation retrieval system at the handling of diverse information retrieval ob-jects.  ...  The main issue of MIMOR is the exploitation of users' relevance feed-back in order to optimise the fusion of several retrieval engines or resources.  ...  Details of this evaluation are described in Li 2002, a master thesis at the University of Hildesheim.  ...

Ad-Hoc Mono- and Bilingual Retrieval Experiments at the University of Hildesheim [chapter]

René Hackl, Thomas Mandl, Christa Womser-Hacker
2006 Lecture Notes in Computer Science  
Based on experience from last year, one of our main objectives was to improve and refine the n-gram-based indexing and retrieval algorithms within our system.  ...  This paper reports on our participation in CLEF 2005's ad-hoc multi-lingual retrieval track. The ad-hoc task introduced Bulgarian and Hungarian as new languages.  ...  We also acknowledge the work of Viola Barth and Joachim Pfister who ported the trec_eval tool to Java.  ...

Evaluation of a language identification system for mono- and multilingual text documents

Olga Artemenko, Thomas Mandl, Margaryta Shramko, Christa Womser-Hacker
2006 Proceedings of the 2006 ACM symposium on Applied computing - SAC '06  
This paper presents the implementation of a tool for language identification for mono-and multi-lingual documents. The tool includes four algorithms for language identification.  ...  For longer texts, the performance is comparable. The tool can also identify language changes within one multi-lingual document.  ...  The University of Hildesheim is working with the web corpus [Jensen 2005 ] and wants to develop an improved language identification tool for this purpose.  ...
