  • Building and using comparable corpora for domain-specific bilingual lexicon extraction [Elektronski vir]
    Fišer, Darja, 1978- ...
    This paper presents a series of experiments aimed at inducing and evaluating domainspecific bilingual lexica from comparable corpora. First, a small English-Slovene comparable corpus from health ... magazines was manually constructed and then used to compile a large comparable corpus on health-related topics from web corpora. Next, a bilingual lexicon for the domain was extracted from the corpus by comparing context vectors in the two languages. Evaluation of the results shows that a 2-way translation of contextvectors significantly improves precision of the extracted translation equivalents. We also show that it is sufficient to increase the corpus for onelanguage in order to obtain a higher recall, and that the increase of the number of new words is linear in the size of the corpus. Finally, we demonstrate that by lowering the frequency threshold for context vectors, the drop in precision is much slower than the increase of recall.
