Recognition and acquisition: Two inter-related activities in corpus-based term extraction

Corpora are not the exclusive source of knowledge in corpus-based term extraction. In particular, pre-existing term bases can be used in conjunction with corpora for extracting terminological knowledge. The advantage is twofold: only terms which are not yet in the base are produced and semantic links are acquired between initial terms and new terminological material. This paper reports on three methods for acquiring terminological knowledge from corpora and occurrences of terms within these corpora: acquisition of terms from recurrent variants, acquisition of terms from variant deconstructions, and acquisition of morphological knowledge from approximate equalities between occurrences.
