LEXICON EXTRACTION FROM NON-PARALLEL DATA

A computer-implemented method executed on a processor for lexicon extraction from non-parallel data is provided. The computer-implemented method includes representing each word of a plurality of words by a vector of documents in which the word appears, modeling each word as a topic distribution by using the vector of documents, receiving a first word in a source language, and finding a second word in a target language as a translation of the first word based on similarity of topic distributions of the first word and the second word.
