The goal of this PoC proposal is to boost the creation of a start-up (AllYours) targeting both Internet users as well as small to medium companies (SME) offering full-fledged personalization in notification systems. The Web is now all about users; they are the greediest bandwidth consumers, the ultimate deciders of which applications are actually adopted and also the most prolific content generators. While social networks have taken off at an unexpected scale and speed, Web navigation has radically changed to the point that notification is taking over search: many users now navigate through the links they discover rather than explicit search operations. Yet, users get quickly overwhelmed with the huge amount of information in a click range. For such notification systems to be truly useful, they should be personalized depending on the user activity, operations, posts, interests. Yet, personalization poses several issues such as scalability (it is expensive to store a large amount of information per user) and privacy (users are more and more reluctant to give away their preferences to large companies). At the same time, SMEs are struggling to provide fully personalized services given the expertise and amount of resources such algorithms require.AllYours is an implicit instant item recommender providing personalization in the notification process without requiring explicit subscriptions to feeds or interests. They only let the system know whether they like the items received or not (eg like/dislike button). In addition, users personal data are stored on their own machine, leaving the space to provide a wide spectrum of privacy guarantees while enabling cross application benefits. Behind the scene, AllYours provides each user with a live social network of participants sharing similar interests, called an implicit social network. AllYours come in two different flavors: (1) Enterprise-AllYours provides a scalable notification and recommendation system targeting all SMEs operating Web content editors & ecommerce sites (2) P2P-AllYours provides a fully decentralized solution without requiring users to ever reveal their private preferences through a clever obfuscation mechanism.
