An integrated narrative generation system, which we develop, generates an event concept by referring to noun and verb concepts than a conceptual dictionary. However, the noun and verb concepts were selected at random. Considering the choice of the noun concept, we used the frequency information and co-occurrence information. Furthermore, we implement a similar method considering the verb concept selection. The method of the verb concept selection based on frequency information assumed in this paper premises that the appearance frequency of all concepts is prepared for. When it is extreme that all the candidates of a certain verb concept are of frequency 0, the concept of selection based on the frequency is in good agreement with the conventional random selection without functioning. Therefore, we suggest a method using the co-occurrence information between the concepts. We demonstrate a calculation result of the frequency information using the co-occurrence information in the verb concept when the frequency information becomes 0, in particular in the calculation method of the frequency information.
