We are studying to model route choice behaviour with words because travelers' psychological states are observed directly and clearly by words from a bottom-up viewpoint. Route choice behaviour is expressed in two stages: “recognize” and “choose” stages. Their thinking processes are clearly described by placing “cognition results” between the two stages. Cognition results are their impressions and feelings of each travel route. This paper shows a method that extracts cognition results out of open-ended questionnaire texts. Once we collect the linguistic knowledge, cognition results can be extracted from texts even if they are unseen. Not only simply extracting words that express cognition results, the extraction of denial is also reported to interpret properly as cognition results. Finally, an experiment on the extraction of cognition results from unseen texts is reported.
