ABSTRACT
This chapter describes how ontological analysis helps pragmatic knowledge modeling; and then how pragmatics impacts the development of natural language ontology. It focuses on Models that have addressed explicitly the entities involved in pragmatics; Linguistic theories that have durably shaped what pragmatics are taken to be about in linguistics. An ontology of natural language has to bring together the ingredients for capturing common aspects between the relations of language to world and to the mental realm. The chapter considers that conversational implicatures are derived from the common ground and sentence meaning. It discusses the well-known distinction of pragmatics within the framework laid down in previous section. However, for linguistic analysis it may introduce more problems than it solves. An important step for proposing ontological work relevant for pragmatics and linguistics is division operated between revisionary metaphysics that tries to identify the 'real' constituents of the world and descriptive metaphysics that aims at describing the world of ordinary experience and thought.
