Social Glue

A Modular Development Platform for Community-oriented Services

Web communities are virtual worlds where people may meet and interact. This interaction may take different forms: sharing data, participating to collaborative tasks, organizing events and activities, entertaining, etc. The incredible spread of Web communities is a recent, and still growing, phenomenon. According to recent statistics, the number of users of Web communities is around hundreds of millions (Facebook alone exceeds 500M of active users).

Although Web communities have become a crucial part of the daily life of more than 1/5 of world population, scientific research in such area has begun quite recently, and many problems remain open. In addition to the well-known issues related to distributed systems (concurrency, heterogeneity, mobility, security, etc.), Web community services are typically provided on a “best effort” basis, without any concrete guarantees e.g. about how privacy issues are dealt with, about the policies which regulate the interaction among users, etc.

A further problem is the lack of sound, well-established methodologies and tools for the development of Web community services. This makes expensive to create and customize communities which have specific features, and which have to run on a variety of different devices, ranging from Web clients to several kinds of tablets and smart-phones.

The “Social Glue” project aims at studying and experimenting new specification, analysis and development techniques for Web communities. Specific goals include:

  • Models, policies and mechanisms for enforcing security and privacy properties;
  • Study of collective behavior which regulate the dynamics of Web communities;
  • Modular development techniques and tools for Web communities;
  • Interaction and integration with mobile platforms

A concrete artifact of our research will be an open-source software platform for the development of community-oriented services.


This project has been partially funded by the Autonomous Region of Sardinia, under project CGM (Coarse Grain Recommendation), through Pacchetto Integrato di Agevolazione (PIA) 2008 “Industria Artigianato e Servizi”.
