OP4L was a 2-year international project, funded by the European Commission within its SEE-ERA.NET PLUS program (project ERA 115/01), with the objective to provide support for advanced, context-aware Learning Process Management (LPM) within Personal Learning Environments (PLEs) as the increasingly important paradigm in online education. The project relied on using Social Semantic Web technologies to generate recommendations for learners, based on their current learning contexts and the state of online presence of members of their social graphs (i.e., network of online connections).
OP4L stands for Online Presence for Learning. Online Presence refers to temporary descriptions of users’ presence in the online world. Most instant messaging tools and social networking services allow users to post descriptions of their temporary state: custom messages, availability and willingness to chat and often visual representations known as avatars. The activity of maintaining this kind of temporary user profiles is no more than creating an image of someone’s presence in the online world, a representation how one wishes to be seen by their contacts – the person's online presence.
The objective of the OP4L project was to develop different kinds of services for the benefit of online learners based on their online presence. These services provide learners with high-quality recommendation regarding the learning activities to take, the learning content to use, and/or who can be contacted for collaboration and/or help provision. All the recommendations are based on the learner’s current learning context and the state of online presence of members of his/her social graph (i.e., network of online connections).
