During the specialized translation process, a revision phase is necessary to validate the initial translation proposed by the translator. This phase, which ensures the consistency of the document produced, requires the preparation of terminological information accessible through glossaries and dedicated management tools. In this work, we propose a methodology to build a bilingual concordancer providing not parallel context but aligned Rich-Knowledge Contexts (KRCs) from specialized comparable corpora. These contexts share bilingual conserved properties between the source and target language within the comparable corpus. KRCs are intended to assist in verifying usage of the term to be translated and its proposed translation. The assessment of the tool that we propose shows that the obtained KRCs are acceptable in order to help the terminological revision.
