The Impact of Part-of-Speech Filtering on Generation of a Swedish-Japanese Dictionary Using English as Pivot Language

A common problem when combining two bilingual dictionaries to make a third, using one common language as a pivot language, is the emergence of false translations due to lexical ambiguity between words in the languages involved. This paper examines if the translation accuracy improves when using part-of-speech filtering of translation candidates. To examine this, two different Japanese-Swedish lexicons were created, one with part-ofspeech filtering, one without. The results show 33 % less translation candidates and a higher quality lexicon when using part-of-speech filtering. It also resulted in a free lexicon of Swedish translations to 40 716 Japanese entries with a 90 % precision, and the conclusion that part-ofspeech filtering is an easy way of improving the translation quality in this context.
