This paper deals with the influence of the context in fuzzy rule base systems. The linguistic variable definition of Zadeh is modified to permit context adaptation, and inference procedure is modified to handle context adaptation when evaluating fuzzy concepts. Procedures to determine context in different situations are provided. Context determination may be viewed as a kind of learning. An app...

With the expansion of mobile Internet, location-based services have become a hot spot in Internet industry. To improve the accuracy and efficiency of the location-based services discovery, researchers in web services recommendation area are still busy looking for method. In this paper, it proposes a LCAMSP model (Location Context Awareness Mobile Service Prediction, LCAMSP) under mobile Interne...

Many location-aware applications rely on data from fine-grained location systems. During deployment such systems require a survey, specifying the locations of their environment-based components. Most current surveying methods are time-consuming, and require costly and bulky equipment. This paper presents the concept of self-surveying, i.e. methods by which a location system can survey itself. S...

Pixed (Project Integrating eXperience in Distance Learning) is a research project attempting to use learners’ interaction logs gathered as learning episodes to provide contextual help for learners trying to navigate their way through an ontology-based Intelligent Tutoring System (ITS). First, we propose a model to describe a learning session, a way to log learners’ interaction and to decompose ...

Since more networking technologies and communication channels have been developed, Internet users have moved their roles from being strictly information consumers to both information consumers and producers. Moreover, users on nets might also be intermediaries, inter-actors, interferences or message providers, even service providers. Information on the Internet is dramatically growing. On one h...

The Rational Choice Theory describes criminal behaviour as a form of means-end decision-making. In contrast, it is often argued that criminal behaviour involves subjective, personal biological and psychological aspects. This paper contributes an agent-based modelling approach for criminal behaviour integrating such subjective aspects with decision-making based on means-end analysis, and illustr...

The need for organizations to operate in changing environments is addressed by proposing an approach that integrates organizational development with information system (IS) development taking into account changes in the application context of the solution. This is referred to as Capability Driven Development (CDD). A meta-model representing business and IS designs consisting of goals, key perfo...

This article discusses the consequences for the fundamentals of interaction design given the introduction of mobile devices with increased sensing capability. Location-aware systems are discussed as one example of the possibilities. The article provides eight challenges to the mobile HCI research community, and makes suggestions for how the International Journal of Mobile HCI could contribute t...

QODI is an ontology-based data integration system (OBDI) comprising both ontology mapping and query reformulation methods. QODI is distinguished in that the ontology mapping algorithm dynamically determines a partial mapping specific to the reformulation of each query. The mapping algorithm decomposes a query into a set of paths, and compares the sets of paths with a similar decomposition of a ...

Recent developments in museum visitors' guides focus on context awareness, personalization and multimodal and multimedia information presentation to individuals and groups of visitors. However, the modern museum is becoming an "Active Museum", which is a special example of an active environment that interacts with its inhabitants. Since recent museum visitors' guides have focused more on the ap...
