... from corpora. The EX approach aims to construct a large and up-to- date transliteration lexicon from live corpora. Towards this objective, some have proposed extracting translation pairs from ... extraction of transliteration pairs (EX) from corpora. The TM approach models phoneme-based or grapheme-based mapping rules using a generative model that is trained from a large bi...

... produced parses from the target domain are used. 1 Introduction In this paper we describe how co-training (Blum and Mitchell, 1998) can be used to boot- strap a pair of statistical parsers from a small amount ... labelled data is drawn from a different distribution to either the unlabelled training material or the test set; that is, we show that co-training can help in porting a parser...

Japan Abstract The present paper will seek to present an approach to bilingual lexicon extrac- tion from non-aligned comparable cor- pora, phrasal translation as well as evalua- tions on Cr...

In other words, a word w 2 from a target language is a potential trans- lation candidate for a word w 1 from a source lan- guage, if the distribution of w...

But for bilingual terminology mining, and for many language pairs, large comparable ... domain, register, media, style or discourse. For lexical alignment from comparable corpora, good results on single words can be obtained from large corpora — several millions words —...
