We describe a new unsupervised approach for synonymy discovery by aligning para- phrases in monolingual domain corpora. For that purpose, we identify phrasal terms that convey most of the concepts within domains and adapt a methodol- ogy for the automatic extraction and align- ment of paraphrases to identify para- phrase casts from which valid synonyms are discovered. Results performed on two different domain corpora show that gen- eral synonyms as well as synonymic ex- pressions can be identified with a 67.27% precision.
