Multiple Location Profiling for Users and Relationships from Social Network and Content

Understand

Users' locations are important for many applications such as personalized search and localized content delivery.

• In this paper, we study the problem of profiling Twitter users' locations with their following network and tweets.
• We propose a multiple location profiling model (MLP), which has three key features: 1) it formally models how likely a user follows another user given their locations and how likely a user tweets a venue given his location, 2) it fundamentally captures that a user has multiple locations and his following relationships and tweeted venues can be related to any of his locations, and some of them are even noisy, and 3) it novelly utilizes the home locations of some users as partial supervision.
• As a result, MLP not only discovers users' locations accurately and completely, but also "explains" each following relationship by revealing users' true locations in the relationship.
