Keywords: Location sharing, location-based service, location
representation, place naming Most location sharing applications display people's locations on a map. 
However, in practice, people use a rich variety of terms to refer to their 
locations when interacting with others, such as "home," "Starbucks," or 
"the bus stop near my house." Our long-term goal is to create a system
that can automatically generate appropriate place names based on real-time 
context and user preferences. As a first step, we analyze data from a 
two-week study involving 26 participants in two different cities, focusing 
on how people refer to places in location sharing. We derive a taxonomy of 
different place naming methods, and show that factors such as a person's 
perceived familiarity with a place and the entropy of that place (i.e. the 
variety of people who visit it) strongly influence the way people refer to 
it when interacting with that person. We proceed with the description of 
a machine learning model for predicting how people name places. Using our
data, this model is able to predict the place naming method people choose 
with an average accuracy higher than 85%.
