150 Digit. Integrating 3D Visit and Social Functions into a Web 3.0 Learning-Oriented Approach

This paper is about the 150 Digit project, a web 2.0 portal designed for the publicity and dissemination of the exhibitions set up for the celebration of the 150 years of Italian unity. Targeted at schools, 150 Digit encourages the active participation of the users to the classification (in terms of tagging) of the exhibition contents and to the creation of new contents. The social components of the portal are leveraged by a semantic layer, which recommends the users with new tags, thus inducing new connections over the exhibits. Content items are recommended as well using both the same semantic strategy and collaborative filtering approaches. As part of the user involvement, 150 Digit features a 3D visit of the exhibitions, where the users can navigate the reconstruction of the exhibitions through a specifically developed web-plugin.
