In 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. We propose a first prototype of bilingual concordancer that takes as input a term and its translation, and provides not parallel but aligned Knowledge-Rich Contexts (KRC) from specialized comparable corpora. Both the manual evaluation and a real experiment with student revisers show that our concordancer can assist revisers as a complement to their habitual ressources, despite the difficulty of the task. MOTS-CLÉS : Contextes riches en connaissances, révision en traduction, concordancier bilingue. Résumé long Qu'il soit indépendant ou salarié, le traducteur ne peut fournir en permanence des traductions irréprochables. Le manque de contextes lors de la phase de traduction renforce la nécessité de contrôles tels que la révision, qui permet d'assurer la cohérence globale du document produit.
