The author investigates techniques used in the translation of highly specialized technical terms. In particular, he analyses how images of technical devices can be used as a language independent representation to find a translation for terms by means of the retrieval of multilingual terminology, as well as to support translation with additional descriptions and information in context. He proposes a new image and concept-based approach to help translate terms designating concrete objects by locating images of the same device in independent documents in different languages. The proposed image-based approach not only provides an alternative to the concept-based translation of highly specialized technical noun phrases in specialized dictionaries but also increases the probability of finding the best translation for noun phrases representing “new” concepts. The experiment described highlights the potential of the Internet to serve as a much wider repository in terms of the amount of retrieved documents than specialized dictionaries and glossaries. Indeed, evidence from the experiment suggests that many of the Spanish terms extracted from specialized dictionaries are mostly translations from English or outdated terms no longer used and documented on the Web.
