Cognitive Computing Systems in Reactive Multimedia Applications Developed in CÉU

The integration of multimedia frameworks and APIs for accessing cognitive computing systems into a unified programming model may not be straightforward. Current solutions use programming models that lead to problems like callback hell or synchronization of threads. In this paper, we explore the use of the reactive programming paradigm to create multimedia applications that explore cognitive computing systems features. By using CÉU as instance of reactive language, we discuss how this approach promotes a straightforward integration between these domains, while avoiding the aforementioned issues. We discuss the implementation of two case studies to illustrate the advantages of this approach.
