This publication provides the completely refereed post-proceedings of a workshop via the Cross-Language review discussion board crusade, CLEF 2002, held in Rome, Italy in September 2002.

The forty three revised complete papers awarded including an creation and run info in an appendix have been conscientiously reviewed and revised upon presentation on the workshop. The papers are prepared in topical sections on platforms assessment experiments, pass language and extra, monolingual experiments, normally domain-specific details retrieval, interactive matters, cross-language spoken record retrieval, and cross-language overview matters and initiatives.

Bioinspiration: From Nano to Micro Scales

Tools in bioinspiration and biomimicking were round for a very long time. notwithstanding, as a result of present advances in smooth actual, organic sciences, and applied sciences, our realizing of the tools have advanced to a brand new point. this can be due not just to the identity of mysterious and engaging phenomena but additionally to the understandings of the correlation among the structural elements and the functionality in accordance with the newest theoretical, modeling, and experimental applied sciences.

The Traveling Salesman Problem and Its Variations

This quantity, which incorporates chapters written via respected researchers, offers the cutting-edge in idea and algorithms for the touring salesman challenge (TSP). The publication covers all very important components of analysis on TSP, together with polyhedral conception for symmetric and uneven TSP, department and sure, and department and reduce algorithms, probabilistic facets of TSP, thorough computational research of heuristic and metaheuristic algorithms, theoretical research of approximation algorithms, together with the rising sector of domination research of algorithms, dialogue of TSP software program and adaptations of TSP corresponding to bottleneck TSP, generalized TSP, prize amassing TSP, maximizing TSP, orienteering challenge, and so on.

Example text

Then the combined, translated Italian topics with term frequencies reduced by half were used to search the Italian document collections. The bky2bienfr, bky2biende, bky2bienes bilingual runs from English were all produced in the same way as the bky2bienit run. For English or French to German bilingual retrieval runs, the words in the title or desc fields of the translated German topics were decompounded. For all bilingual runs, words were stemmed after removing stopwords as for monolingual 42 Aitao Chen Table 8.

The second approach translates a multilingual document collection into the topic language. Then the topics are used to search against the translated document collection. The third approach also translates topics to all document languages as in the first approach. The source topics and the translated topics are concatenated to form a set of multilingual topics.

For Dutch decompounding, we used a Dutch wordlist of 223,557 words [16]. From this wordlist we created a Dutch base dictionary of 210,639 words by manually breaking up the long words that appear to be compounds. It appears that many Dutch compound words still remain in the base dictionary. 40 Aitao Chen Table 6. Dutch monolingual retrieval performance on CLEF 2002 test set. The title and description fields in the topics were indexed. 54% recall 1562 1623 1584 1614 1633 1727 1702 1734 Like the German base dictionary, an ideal Dutch base dictionary should include all and only the words that should not be further decomposed.
