Abstract Due to the pervasiveness of positioning technology combined with the
proliferation of socially-oriented web sites, community-contributed spatio-tempo-
ral data of people's historical positions are available today in large amounts. The
analysis of these data is valuable to scientists and can provide important infor-
mation about people's behavior, their movement, geographical places, and events.
In this paper, we develop a conceptual framework and outline a methodology that
allows us to analyze events and places using geotagged photo collections shared by
people from many countries. These data are often semantically annotated by titles
and tags that are useful for learning facts about the geographical places and for
detecting events occurring in these places. The knowledge obtained through our
analysis carries an additional benefit. For example, it may also be utilized by local
authorities, service providers, tourist agencies, in sociological and anthropological
studies or for building user centric applications like tour recommender systems. We
provide a conceptual foundation for the analysis of spatio-temporal data of places
visited by people worldwide using community contributed geotagged photo col-
lections. First, we define several types of spatio-temporal clusters of people's visits.
Second, we discuss methods that can be used for analysis of these clusters. Third,
we offer an analysis of tourist activities in Switzerland based on a case study.
