This paper describes the work done at the University of Hagen for our participation at the German Indexing and Retrieval Test (GIRT) task of the CLEF 2004 evaluation campaign. We conducted both monolingual and bilingual information retrieval experiments. For monolingual experiments with the German document collection, the focus is on applying and comparing three indexing methods targeting full ...

The availability of machine-readable bilingual linguistic resources is crucial not only for machine translation but also for other applications such as cross-lingual information retrieval. However, the building of such resources demands extensive manual work. This paper describes a methodology to build automatically bilingual dictionaries and transfer rules by extracting knowledge from word-ali...

The automatic compilation of bilingual dictionaries from comparable corpora has been successful for single-word terms (SWTs), but remains disappointing for multi-word terms (MWTs). One of the main problems is the insufficient coverage of the bilingual dictionary. Using the compositional translation method improved the results, but still shows some limits for MWTs of different syntactic structur...

Named entity phrases are some of the most difficult phrases to translate because new phrases can appear from nowhere, and because many are domain specific, not to be found in bilingual dictionaries. We present a novel algorithm for translating named entity phrases using easily obtainable monolingual and bilingual resources. We report on the application and evaluation of this algorithm in transl...

We present a three-part bilingual specialized dictionary Mexican Sign Language-Spanish / Spanish-Mexican Sign Language. This dictionary will be the outcome of a three-years agreement between the Italian “Consiglio Nazionale delle Ricerche” and the Mexican Conacyt. Although many other sign language dictionaries have been provided to deaf communities, there are no Mexican Sign Language dictionari...

This paper presents how we adapted a website search engine for cross language information retrieval, using the Uplug word alignment tool for parallel corpora. We first studied the monolingual search queries posed by the visitors of the website of the Nordic council containing six different languages. In order to compare how well different types of bilingual dictionaries covered the most common ...

In this paper, the main features of manually produced bilingual dictionaries, which have been originally designed for human use, are considered. The problem is to find the way to use such kind of dictionaries in order to produce bilingual language resources that could make a base for automate text processing, such as machine translation, cross-lingual interrogation in text retrieval, etc. The t...

The aim of our software presentation is to demonstrate that corpus-driven bilingual dictionaries generated fully by automatic means are suitable for human use. Need for such dictionaries shows up specifically in the case of lesser used languages where due to the low demand it does not pay off for publishers to invest into the production of dictionaries. Previous experiments have proven that bil...

The thesis proposes creating bilingual dictionaries and Wordnets for languages without many lexical resources using resources of resource-rich languages. Our work will have the advantage of creating lexical resources, reducing time and cost and at the same time improving the quality of resources created.

A statistical algorithm for extracting bilingual term dictionaries (thesauri) from parallel text is presented, along with reenements for improving their size and accuracy. Somewhat paradoxically , increasing the accuracy of the extracted thesaurus can in fact reduce the performance of an IR system using it to perform query translation for cross-language information retrieval.
