Switching through the variety of available TV channels to find the most acceptable program at the current time can be very time-consuming. Especially at the prime time when there are lots of different channels offering quality content it is hard to find the best fitting channel.This paper introduces the TV Predictor, a new application that allows for obtaining personalized program recommendations without leaving the lean back position in front of the TV. Technically the usage of common Standards and Specifications, such as HbbTV, OIPF and W3C, leverage the convergence of broadband and broadcast media. Hints and details can overlay the broadcasting signal and so the user gets predictions in appropriate situations, for instance the most suitable movies playing tonight. Additionally the TV Predictor Autopilot enables the TV set to automatically change the currently viewed channel. A Second Screen Application mirrors the TV screen or displays additional content on tablet PCs and Smartphones.Based on the customers viewing behavior and explicit given ratings the server side application predicts what the viewer is going to favor. Different data mining approaches are combined in order to calculate the users preferences: Content Based Filtering algorithms for similar items, Collaborative Filtering algorithms for rating predictions, Clustering for increasing the performance, Association Rules for analyzing item relations and Support Vector Machines for the identification of behavior patterns. A ten fold cross validation shows an accuracy in prediction of about 80%.TV specialized User Interfaces, user generated feedback data and calculated algorithm results, such as Association Rules, are analyzed to underline the characteristics of such a TV based application.

Complex event processing (CEP) matches patterns over a continuous stream of events to detect situations of interest. Yet, the definition of an event pattern that precisely characterises a particular situation is challenging: there are manifold dimensions to correlate events, including time windows and value predicates. In the presence of historic event data that is labelled with the situation to detect, event patterns can be learned automatically. To cope with the combinatorial explosion of pattern candidates, existing approaches work on a type-level and discover patterns based on predefined event abstractions, aka event types. Hence, discovery is limited to patterns of a fixed granularity and users face the burden to manually select appropriate event abstractions. We present IL-M iner , a system that discovers event patterns by genuinely working on the instance-level, not assuming a priori knowledge on event abstractions. In a multi-phase process, IL-M iner first identifies relevant abstractions for the construction of event patterns. The set of events explored for pattern discovery is thereby reduced, while still providing formal guarantees on correctness, minimality, and completeness of the discovery result. Experiments using real-world datasets from diverse domains show that IL-M iner discovers a much broader range of event patterns compared to the state-of-the-art in the field.
