Automatic Multimodal Aggregation of News from Television and the Web

This demonstration concerns a system designed and implemented to automatically build multimodal aggregations of informative news items coming from the two domains of digital television and the Web. Though in recent times several technological solutions have addressed the problem of clustering online articles, little is available which is capable of integrating these two sources of information. The demonstrated system is based on a novel hybrid clustering approach able to construct a directed graph of items representing a certain event (e.g., the tour of the Olympic torch), and to deliver an RSS service in which each item includes contributions coming from the two domains. In-house experimental evaluations have already proved the efficacy and accuracy of the service.
