1. A computer-implemented method comprising: identifying, using one or more computers, a plurality of transliterated terms in a target language; for each transliterated term of the plurality of transliterated terms in the target language, mapping the transliterated term to one or more terms in a source language; and for a first transliterated term of the plurality of transliterated terms in the target language, identifying one or more second transliterated terms of the plurality of transliterated terms in the target language as candidate synonyms of the first transliterated term, where each of the one or more second transliterated terms is mapped to at least one term in the source language that is also mapped from the first transliterated term.
