This presentation addresses acquisition and utilization of semantics around us, especially that of social relation between people and function of place. Assume we can acquire a user's behaviour in a ubiquitous environment and try to utilize it for information support. We have to have knowledge behind the user's behaviour.
For example, if we get a user's location, we need the knowledge about the space. It is also important to have knowledge about social relation among users to infer the user's context in order to acquire the knowledge, we use Web mining approach. We also propose a representation to describe spatial function.
