ULiS: An Expert System on Linguistics to Support Multilingual Management of Interlingual Knowledge bases

We are interested in bridging the world of natural language and the world of the seman-tic web in particular to support multilingual access to the web of data, and multilingual management of interlingual knowledge bases. In this paper we introduce the ULiS project, that aims at designing a pivot-based NLP technique called Universal Linguistic System, 100 % using the semantic web formalisms, and being compliant with the Meaning-Text theory. Through the ULiS, a user could inte-ract with an Interlingual Knowledge base (IKB) in controlled natural language. Lin-guistic resources themselves are part of a specific IKB: The Universal Lexical Know-ledge base (ULK), so that actors may en-hance their controlled natural language, through requests in controlled natural lan-guage. In this paper we propose a basic inte-raction scenario at the system level, and then we propose and overview the layered archi-tecture of ULiS: meta-ontology, ontology, facts; and ontology, interlingual knowledge, situational knowledge.
