Playsound.space: enhancing a live music performance tool with semantic recommendations

Playsound is an experimental client for the Freesound API. Its main aim is to provide a simple and intuitive tool for the collaborative composition based on Freesound samples. In this paper, an approach based on Semantic Web technologies to provide recommendations to Playsound users is presented. A Semantic Web of Things architecture is proposed, showing loosely coupled, independent software agents interoperating by means of a semantic publish/subscribe platform and a set of ontologies to describe agents, audio contents, input/output of audio analytics tools and recommendations. Preliminary tests show that the designed architecture adapts well to environments where services can be discovered and seamlessly orchestrated on the fly, resulting in a dynamic workflow.
