In this paper, we propose a non-task-oriented dialog system which uses multiple language resources. This system can generate dynamic dialogues by two methods: one is using the Web; another is using the language resources such as Japanese Google N-grams and Nihongo-goitaikei. First, the system collects Web pages' data by Web retrieval after doing morphological analysis for the user input. Then the system extracts candidate topic terms from the data and determines a way of dialog generation according to the extracted terms. In the case of using Google N-grams, the system generates dialogs by searching N-grams after the terms and connects words recursively. In the case of the Web, the system collects Web pages with extracted words and their referential words. After that, the system generates the sentence by clipping sentence which includes extracted word. We carried out experiments to evaluate the proposed system.
