Intelligent Services for the Elderly Over the TV

The TV is usually considered just another channel to receive information and services. However, for certain users with special needs, such as the Disabled and Elderly, TV based interfaces could become the only suitable way to defeat interfacing barriers and enter the Information Society.Elderly users have special requirements with respect to user interfacing approaches and home delivered services. The EC funded project SAID proposes the combination of iTV technologies, agents based intelligent services and innovative “active” interfaces as the best way overcome the reluctancy elderly users show to the introduction of ICT technologies in their home environment. SAID uses state of the art agent technology to implement the following services: intelligent information assistants on the TV, automatic suggestions engine based on a stored user profile, automatic user monitoring and profile acquisition and intelligent mobile visits planner running over GPRS.     

SEWEBAR-CMS: semantic analytical report authoring for data mining results

SEWEBAR-CMS is a set of extensions for the Joomla! Content Management System (CMS) that extends it with functionality required to serve as a communication platform between the data analyst, domain expert and the report user. SEWEBAR-CMS integrates with existing data mining software through PMML. Background knowledge is entered via a web-based elicitation interface and is preserved in documents conforming to the proposed Background Knowledge Exchange Format (BKEF) specification. SEWEBAR-CMS offers web service integration with semantic knowledge bases, into which PMML and BKEF data are stored. Combining domain knowledge and mining model visualizations with results of queries against the knowledge base, the data analyst conveys the results of the mining through a semi-automatically generated textual analytical report to the end user. The paper demonstrates the use of SEWEBAR-CMS on a real-world task from the cardiological domain and presents a user study showing that the proposed report authoring support leads to a statistically significant decrease in the time needed to author the analytical report.
