Abstract: The present invention provides a system, method, and applications for providing personalized user experiences based on the use of a core ontology and inferencing over the ontology using rules provided by a domain expert. The population of users may be known to a commerce or information service from external and internal user data sources. Information (data) about this population is brought into a knowledge warehouse designed for on-line analytic processing, and potentially data marts. Data can be sourced from external databases in batch or streaming mode and enhanced with real-time click stream events from internal observed user interactions. A reference ontology is either loaded into the system or defined via a domain expert. The ontology forms the central reference point for data enrichment and precise personalization. Characteristic data is tagged in accordance with direct reference to the nodes of the ontology and may be enhanced via inferencing techniques.

Abstract: A multi-line, multi-instrument telephone system having no key service unit and wherein decentralized or local indicator lamp and paging circuit management functions are provided which are operative independently in each station set to operate and control the indicator lamps and paging circuits through selective local generation and alteration of control signals and comparison of the control signals with locally generated reference voltage signals to provide basis for decisions on required visual and audible indicator status. The system is connected in loop fashion with each instrument being connected across a common, multiconductor buss wherein a single conductor supports lamp supervision signaling for the multiple lines and another single conductor supports intercom status signaling, intercom audio, paging audio, and the ring signal.
