Informatics colloquium 27. 2. Managing and Analyzing Big Geo-Social DataInformatics colloquium 27. 2. 2018, 14:00 lecture hall D2 asst. prof. Dimitris Sacharidis, Ph.D., Institute of Information Systems Engineering, TU Wien Managing and Analyzing Big Geo-Social Data Abstract: The widespread adoption of online social networks and location-aware mobile devices has resulted in a continuously increasing amount of published user-generated, geo-tagged content. Typical examples include tweets, check-ins, photo/video uploads, route posts (e.g., taxi rides, running trails). This big geo-social data essentially captures people's everyday interactions between the physical and digital world, and presents immense opportunities for creating added value to domains such as location-based services, smart cities, tourism. In this talk, we will present methods for efficiently handling and effectively analyzing large amounts of such data.
