Section 5 shows the evaluation and finally, Section 6 concludes the paper with some remarks and suggests future research lines.2.?Related WorkContext-aware research falls into two categories with the focus on context theory and establishing and developing standard context-aware models and methodologies. Semantic technologies, more precisely phosphatase inhibitor ontologies, bridge between these two categories. From a context theory perspective, the work carried out by researchers was basically focused on defining the theoretical and conceptual foundations of context-awareness. They developed a number of applications in order to test their theory, however, the theoretical Inhibitors,Modulators,Libraries work carried was so intense that the most relevant definitions of context Inhibitors,Modulators,Libraries were put forward throughout those years Inhibitors,Modulators,Libraries [14�C16].
Analyses of context management methods [10] indicate that ontologies take in adequate functionalities for context information management. Hence, several authors working on context-awareness started to Inhibitors,Modulators,Libraries use semantic technologies in order to model context and manage context information. This set the way for systems to share, integrate, exchange and re-use context information, and moreover, it enabled not only checking the models consistency but also inferring implicit context knowledge [17,18]. Researchers conducting this work were primarily focused on finding standard context management methods rather than in the development of the theory that supported them. This research falls into the second category of context-aware research.Several mobile tourism guide surveys have already been published [3,19,20].
The first two reviews primarily analyse early generation visitor guides and investigate specific issues, such as support for maps or mobility GSK-3 aspects. However, they often do not provide a comprehensive insight into the kinds of services that are supported, and moreover, in depth technical aspects of how these services are delivered to the end-user are also not described. Mobile tourism guides either provide location-based information services or concentrate on delivering personalized information, i.e., they fail to provide a combination of both as a rudimentary context-aware kind of service [3].There are just two examples of real context-aware mobile tourism guides [4,5]. Interestingly, although the CAIPS system [4] provides rule-based push information, it fails to provide a general framework to support visitors, since it is more focused on creation of rules for information delivery.
Therefore, from an epistemological point of view, there is some room for research on contextual computing in tourism.3.?Contextual Computing in TourismTwo fundamental issues are addressed in order inhibitor KPT-330 to accomplish the objectives pursued by the CONCERT Framework: Firstly, the conceptual approach to the notion of context in CONCERT is different from the existing ones.
