Trajectory2Vec: A Visual Analytics Approach for Urban Mobility Patterns Based on Mobile Phone Data

Based on word embedding model,we map the spatio-temporal information of base stations to the vector space and calculate the similarity rule of the high-level semantics between base stations to analyze the social information of geographical areas.Moreover,we designed and implemented a visual analysis system to explore the relationship between urban interregional functions.Case studies show that the proposed system can effectively help users to analyze the dynamic changes of the relationship between urban area and local residents.
