Cohen and Levesque have developed a theory of rational action that can be used to guide the actions of an intelligent agent. A fundamental building block of Cohen and Levesque's theory is their notion of a persistent goal. In this paper, we extend persistent goals by recasting them in terms of add/drop conditions, and introducing time intervals. These two extensions are then used to deene time-...

WEAR is a Web-based authoring tool for the construction of Intelligent Tutoring Systems (ITSs) in Algebra-related domains, such as physics, economics, chemistry, etc. In WEAR’s authoring environment instructors are able to construct problems and tests and also build adaptive electronic textbooks. In return, WEAR generates a learning environment in which students can solve problems and study the...

Embedding analytics is about integrating data analytics into operational systems that are part of an organization’s business processes. Currently, most organizations focus on automation business processes and enhancing productivity. However, going forward, in order to stay competitive, organizations have to go beyond automating their processes, by making them more intelligent, by embedding anal...

Artificial potential fields(APF) are well established for reactive navigation of mobile robots. This paper describes a fast and robust fuzzy-APF on an ActivMedia AmigoBot.Obstacle-related information is fuzzified by using sensory fusion, which results in a shorter runtime. In addition, the membership functions of obstacle direction and range have been merged into one function, obtaining a small...

This paper characterises key weaknesses in the ability of current digital libraries to support scholarly inquiry, and as a way to address these, proposes computational services grounded in semiformal models of the naturalistic argumentation commonly found in research literatures. It is argued that a design priority is to balance formal expressiveness with usability, making it critical to co-evo...

Knowledge management is used for handling knowledge and activities in real world context. However, knowledge management can also be used for the modelling of robot activities in a real world context. Although robot technology is still under development, Intelligent Service Robots are slowly becoming a reality. The programming of these robots to support a closer interaction with the users is a c...
