 note = {In this study, we propose a method that uses machine learning to infer the intentions of visiting places or attending events from Twitter. Our method aims at distinguishing similar but different intentions such as "Want to go'' and "Confirm to go.'' We describe the outline of our proposed method. We also discuss several research chal-lenges in preparing training data, extracting useful features, and building accurate classification mod-els.Keywords: Twitter, intensions, events, spa-tio-temporal data, machine learning},
