An Extensible Framework for Interactive Real-Time Visualizations of Large-Scale Heterogeneous Multimedia Information from Online Sources

摘要

This work presents the user-centered design and development of a generic and extensible visualization framework that can be re-used in various scenarios in order to communicate large-scale heterogeneous multimedia information obtained from social media and Web sources, through user-friendly interactive visualizations in real-time. Using the particular framework as a basis, two Web-based dashboards demonstrating the visual analytics components of our framework have been developed. Additionally, three indicative use case scenarios where these dashboards can be employed are described. Finally, preliminary user feedback and improvements are discussed, and directions for further development are proposed on the basis of the findings.
