Smiley Ontology
People use emoticons every day as the easiest and most interesting way to express their emotions, state, or action. But their use is limited for many reasons. Smiley Ontology is an ontology that aims to enable interchange of emoticons between different systems, without any loss of their semantics, as well as to allow for captureing and formal representation of semantics of emotions and emotional states that are widely spread across the Web.

Online Presence
The aim of Modeling Online Presence (OPO) is to model the dynamic aspects of a user's presence online and to enable the integration and exchange of Online presence related data. For this purpose the project provides a Semantic Web ontology (OPO) for representing rich data about Online Presence in RDF.
For manipulation with user's online presence data, we developed Java library that enables it.
