Unsupervised Spatio-Temporal Embeddings for User and Location Modelling

Many social network applications depend on robust representations of spatio-temporal data. In this work, we present an embedding model based on feed-forward neural networks which transforms social media check-ins into dense feature vectors encoding geographic, temporal, and functional aspects for modelling places, neighborhoods, and users. On the basis of this model, we further propose a Spatio...

Mobile Location Prediction in Spatio-Temporal Context

The increasing use of mobile devices and popular mobile services has led to massive availability of mobile data. Location prediction is a specific topic in mobile data mining, with its potential application in traffic planning, location-base advertisement, and user oriented coupon dispersion. Traditional location prediction methods often separately consider spatial or temporal approach. Althoug...

PhotoMap: from location and time to context-aware photo annotations

Despite the growth of geotagged multimedia data on the Web, spatial and temporal metadata are still poorly exploited by Web search engines and multimedia systems. Interpretation and inference processes can enlarge these metadata towards high quality information that are useful for annotating multimedia automatically. In this paper, we propose a semi-automatic approach for annotating personal ph...

What Do Context Aware Electronic Alerts from Virtual Learning Environments Tell Us about User Time & Location?

The paper describes the analysis of user location and time stamp information automatically logged when students receive and interact with electronic updates from the University’s virtual learning environment. The electronic updates are sent to students’ mobile devices using RSS feeds. The mobile reception of such information can be received in three dimensions of context: time, location and act...
