However, context has traditionally been studied in other research disciplines [8�C10]. Nonetheless, there are various examples of tourism selleck compound mobile guides [3], in which the notion of context has been directly imported from the previously mentioned fields without specifically addressing the characteristic requirements of context within the domain of travellers. This lack of sufficient theoretic support has lead to an oversimplified understanding of context. Thus, understanding the notion of context within the framework of human mobility is essential not only to derive a sound model for computing devices to process context information in a meaningful way [11], but also to delimit and elucidate the notion of context in tourism.
In addition, traditional context-aware applications rely on Inhibitors,Modulators,Libraries networks of sensors to collect contextual information, Inhibitors,Modulators,Libraries which makes them dependent on the particular infrastructure needed to gather contextual information, their hardware infrastructure and corresponding communication protocols [12]. Most of these are pull-based applications and thus require intensive human intervention. In the case of tourism this manipulation is somewhat restricted due to the small size of screens and keyboards in mobile devices, as well as knowledge about the infrastructure deployed in the new Inhibitors,Modulators,Libraries places visited. These appear to be limiting factors when applied to the domain of tourism, where push-based information systems have shown to encourage tourists to use technology-based information systems [4,13].
Motivated by all of the above, this paper presents a specific approach to context-aware information dissemination for travellers based upon a push/filter paradigm, named CONCERT. This framework is built following the statistical recommendations on visitor classification established by the UNWTO [7]. It must fulfil two Inhibitors,Modulators,Libraries requisites. The first Entinostat one is that a network of ontologies approach can be used to model the context of a visitor and provide her with useful information using description logics and rule based reasoning. The second one is that visitors are satisfied with the results. The model is a semantic-based visitor-centred model for context on the realm of tourism. First a theoretical approach to context in the realm of tourism is established. The research work continues by focusing on how a semantic-based rule filtering engine provides visitors with relevant information according to their context.
To do so, the Internet has been used as primary source of information for both context and tourism information, and also with digital broadcasting as (push) communication technology to disseminate context and tourism information.The remaining of the paper is structured as follows. Section 2 presents briefly the related work. Section 3 shows the main theoretic research inhibitor Gefitinib work carried out, as well as its corresponding semantic model.
