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

International audienceWe are interested in bridging the world of natural language and the world of the semantic 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 interact with an Interlingual Knowledge base (IKB) in controlled natural language. Linguistic resources themselves are part of a specific IKB: The Universal Lexical Knowledge base (ULK), so that actors may enhance their controlled natural language, through requests in controlled natural language. In this paper we propose a basic interaction scenario at the system level, and then we propose and overview the layered architecture of ULiS: meta-ontology, ontology, facts; and ontology, interlingual knowledge, situational knowledge
