Integrated Narrative Generation System (INGS) is a framework for integrating our previous researches on narrative generation. INGS integrates various narrative generation modules into an organic architecture. This paper presents a verb conceptual dictionary and a noun conceptual dictionary to be used in INGS. Each of the dictionaries has a conceptual hierarchy with single inheritance by is-a relations. A terminal concept in the verb conceptual dictionary describes one or more case frame(s), the constraints of the main elements and a sentence pattern. The basic description of each terminal concept in the noun conceptual dictionary associates the concept to the other noun concept. The purpose of the study is not developing general conceptual dictionaries, but building them as a mechanism in narrative generation, especially in INGS. Actually, we have combined the two developed conceptual dictionaries with INGS. In this paper, we will present the basic mechanisms based on the cooperation of two types of conceptual dictionary through an implemented narrative generation system, INGS.
