Extracting Translation Pairs from Comparable Corpora through Graph-based Label Propagation

Extracting Transliteration Pairs from Comparable Corpora

Transliterating words and names from one language to another is a frequent and highly productive phenomenon. For example, English word cache is transliterated in Japanese asキャッシュ “kyasshu”. In many cases, recent transliterations are not recorded in machine readable dictionaries so it is impossible to rely on dictionary lookup to find transliteration equivalents. In this paper we describe a meth...

Bilingual Lexicon Extraction from Comparable Corpora Using Label Propagation

This paper proposes a novel method for lexicon extraction that extracts translation pairs from comparable corpora by using graphbased label propagation. In previous work, it was established that performance drastically decreases when the coverage of a seed lexicon is small. We resolve this problem by utilizing indirect relations with the bilingual seeds together with direct relations, in which ...

Extracting Low-Frequency Translation Pairs From Japanese-English Bilingual Corpora

Extracting Multilingual Topics from Unaligned Comparable Corpora

Topic models have been studied extensively in the context of monolingual corpora. Though there are some attempts to mine topical structure from cross-lingual corpora, they require clues about document alignments. In this paper we present a generative model called JointLDA which uses a bilingual dictionary to mine multilingual topics from an unaligned corpus. Experiments conducted on different d...

Extracting bilingual terminologies from comparable corpora

In this paper we present a method for extracting bilingual terminologies from comparable corpora. In our approach we treat bilingual term extraction as a classification problem. For classification we use an SVM binary classifier and training data taken from the EUROVOC thesaurus. We test our approach on a held-out test set from EUROVOC and perform precision, recall and f-measure evaluations for...
