A Systematic Spatial and Temporal Sentiment Analysis on Geo-Tweets
TL;DR: Local users’ sentiments extracted from Geo-tweets data from January to December 2016, analyzed in the spatial and temporal perspective are explored, finding patterns which demonstrate the associations between the nature of Twitter content and the characteristics of places and users.
Journal ArticleDOI
Urban crime prediction based on spatio-temporal Bayesian model.
TL;DR: Of the diverse socio-economic variables associated with crime rate, including population, the number of local internet bars, hotels, shopping centers, unemployment rate, and residential zones, this study finds that the burglary crime rate is significantly correlated with the average resident population per community and number ofLocal internet bars.
Journal ArticleDOI
Human interaction recognition using spatial-temporal salient feature
TL;DR: A novel method for human interaction recognition based on 3D skeleton data captured by Kinect sensor using hierarchical spatial-temporal saliency-based representation method, which demonstrates that the average recognition accuracy is 90.29%, outperforming methods using other features.
Journal ArticleDOI
Prediction of Suspect Location Based on Spatiotemporal Semantics
TL;DR: A novel location prediction model called CMoB (Crime Multi-order Bayes model) based on the spatiotemporal semantics to enhance the prediction performance and significantly outperforms state-of-the-art algorithms for suspect location prediction in the context of data sparsity.
