A Supervised Method to Enhance Vocabulary with the Creation of Domain Specific Lexica

This paper proposes a method to enhance lexica by processing domain specific corpora. The proposed method relies on the identification of the more relevant unknown terms in each domain corpus. The innovative points of the proposed approach is to automatically detect unknown terms using MTMDD technology to handle lexical structures, and to automatically rank and identify domain specific terms using gini and tf-dcf indices. The proposed method is experimented in six corpora in order to illustrate its benefits.
