In this paper, we exploit domain-specific comparable corpora to build bilingual terminologies. We present the monolingual term extraction and the bilingual alignment that will allow us to identify and translate high specialised terminology. We stress the huge importance of taking into account both simple and complex terms in a multilingual environment. Such linguistic diversity implies to combine several methods to perfect accurately both monolingual and bilingual terminology extraction tasks. The methods are implemented in TTC TermSuite based on a UIMA framework.
