Keynote 3: Data Analytics of Mobility Entities Currently, we have a huge amount of georeferenced data (e.g., GPS records, cell phone data records, and geotagged social media) generated by humans and different sorts of vehicles. Such data provides fundamental observations about human activities and behaviors. The knowledge extraction from these data can offer unprecedented opportunities in different areas such as social and economic progress, urban planning, smart cities, and service provision. These are examples that can benefit from such analysis of this large data collection. In this tutorial, we will present and discuss what can be accomplished from the analysis of this mobility data considering different types of mobility data and the corresponding data analytics techniques.

A Survey on Big Data for Trajectory Analytics Trajectory data allow the study of the behavior of moving objects, from humans to animals. Wireless communication, mobile devices, and technologies such as Global Positioning System (GPS) have contributed to the growth of the trajectory research field. With the considerable growth in the volume of trajectory data, storing such data into Spatial Database Management Systems (SDBMS) has become challenging. Hence, Spatial Big Data emerges as a data management technology for indexing, storing, and retrieving large volumes of spatiotemporal data. A Data Warehouse (DW) is one of the premier Big Data analysis and complex query processing infrastructures. Trajectory Data Warehouses (TDW) emerge as a DW dedicated to trajectory data analysis. A list and discussions on problems that use TDW and forward directions for the works in this field are the primary goals of this survey. This article collected stateoftheart on Big Data trajectory analytics. Understanding how the research in trajectory data are being conducted, what main techniques have been used, and how they can be embedded in an Online Analytical Processing (OLAP) architecture can enhance the efficiency and development of decisionmaking systems that deal with trajectory data.
