The aim of CACAO is to provide an infrastructure to the end-user that enables him/her to type queries in his/her own language and retrieve documents and objects in any available language. The sound integration of CACAO's infrastructure designed for multilingual purposes with current digital library and catalogue systems will be reached by coupling natural language processing techniques with existing information retrieval systems. CACAO will deliver tools for the maintenance of multilingual resources in the retrieval context..
