The advent of price and product comparison sites now makes it even more important to retain customers and identify those that might be at risk of leaving. The use of data mining methods has been widely advocated for predicting customer churn. This paper presents two case studies that utilize...

This paper proposes a strategy for representing constraints in a conceptual graph knowledge base. We describe a set of techniques for using these constraints to detect inconsistencies in a knowledge base by finding sets of nodes that are inconsistent with these constraints. The detection method...

Formal Concept Analysis provides the mathematical notations for representing concepts and concept hierarchies making use of order and lattice theory. This has now been used in numerous applications which include software engineering, linguistics, sociology, information sciences, information...

This paper reports the use of Conceptual Graphs and Peirce Logic by enterprise architects, who need to capture conceptual context represented in business terms, which differ conceptually from the same terms used in the medical context. For example, in a UK Mobile NHS case study the medical...

This paper highlights the concepts behind the Valletta Travel Information Service (VaTIS) Project, an intelligent information system capable of harvesting data from a road pricing system using automatic number plate recognition (ANPR) technology and low cost sensors installed throughout the city...

Since the amount of people living in cities is expected to increase to 70% by 2050, cities will face many social and urbanisation challenges, and they will need to operate with reduced budgets and limited number of staff. The productivity of computers offers means to address city challenges and...

Parks and green spaces have been allocated for city residents to offer them healthier natural environments. However, people living in cities may have less opportunity to engage with the natural environment since parks seem to be passive locations of activity. We investigated how to proactively...

This paper presents a mobility monitoring system, based on the detection of Bluetooth and WiFi signals emitted by personal portable devices. The work also describes its possibilities of tracking in two real scenarios, one inside the Spanish city of Granada, and another one in a highway between...
