Ontologies, as knowledge engineering tools, allow information to be modelled in ways resembling to those used by the human brain, and may be very useful in the context of personal information management (PIM) and Task Information Management (TIM). This work proposes the use of ontologies as a long-term knowledge store for PIM-related information, and the use of spreading activation over ontolog...

In application areas like personal information agents and intelligent tutoring systems, user models typically maintain sophisticated representations of personal interest profiles and knowledge / skill levels. These representations can be utilized for effective information retrieval and filtering as well as for personalized information presentation. Information delivery services within organizat...

In this paper, we present a dialog system that extends the planbased approach with two features. Instead of Boolean inference, we include into the system the probabilistic measures from the front-end speech and language processes. As a result, rules can be activated and facts gathered based on statistical confidence measures. We also introduce the notion of entity types to classify the rules an...

Statistical process control (SPC) theory takes a negative view of adjustment of process settings, which is termed tampering. In contrast, quality and lean programmes actively encourage operators to acts of intervention and personal agency in the improvement of production outcomes. This creates a conflict that requires operator judgement: How does one differentiate between unnecessary tampering ...
