Today’s tourists expect to get personalized access to tourism information at anytime, from anywhere with any media. Mobile tourist guides provide the user with such a ubiquitous access. The prerequisite for this is the notion of customization, requiring awareness of the applications context together with appropriate adaptation mechanisms. Currently, there is a proliferation of mobile tourist guides, proposing an unmanageable number of diverse functionalities. This chapter sheds light on those approaches by identifying their strengths and weaknesses, thus providing the basis for next-generation mobile tourist guides. For this, an evaluation framework is used comprising detailed criteria for the two orthogonal dimensions of context and adaptation.
Abstract-In recent years business-to-business (B2B) ecommerce has been subject to major rethinking. A paradigm shift from document centric file-based interchange of business information to process-centric and service-based information exchange can be observed. On a business level, a lot of work has been done to capture business models and collaborative business processes of an enterprise. On a technical level, the focus in software development is moving towards service-oriented architectures (SOA). These transitions on both levels promise a market entry at lower costs and an easier adjustment to changing market conditions. Hence, an overwhelming quantity of specifications and approaches emerged in the past targeting the area of B2B -these are partly competing and overlapping. In this paper, we provide a survey of the most promising ones at both levels and classify them using the Open-edi reference model standardized by ISO. Furthermore, we discuss how individual specifications on different levels fit together -starting from business models via business processes to artifacts ready for deployment.
In recent years a technological and sociological paradigm shift has taken place in the Internet that is often referred to as Web 2.0. Companies and individuals have started to adapt existing Web sites to the new standards and principles and created new types of Web services and communities. The tourism domain is no exception to this trend-new tourism communities emerged and long-established ones integrated new features to keep up with this trend. In this paper we are evaluating eight tourism communities with respect to Web 2.0. Each community is evaluated based on a criteria catalogue that draws ideas from online community studies. The findings are discussed in the context of the tourist life cycle that is structured in a pre-trip, on-site and after-trip phase. The value for the traveller is highlighted for each phase and potential problems are discussed.

In recent years business-to-business (B2B) e-commerce has been subject to major rethinking. A paradigm shift can be observed from document centric filebased interchange of business information to process-centric and, finally to servicebased information exchange. On a business level, a lot of work has been done to capture business models and collaborative business processes of an enterprise; further initiatives address the identification of customer services and the formalization of business service level agreements (SLA). On a lower, i.e., technical level, the focus is on moving towards service-oriented architectures (SOA). These developments promise more flexibility, a market entry at lower costs and an easier IT-alignment to changing market conditions. This explains the overwhelming quantity of specifications and approaches targeting the area of B2B-these approaches are partly competing and overlapping. In this paper we provide a survey of the most promising approaches at both levels and classify them using the Openedi reference model standardized by ISO. Whereas on the technical level, serviceoriented architecture is becoming the predominant approach, on the business level the landscape is more heterogeneous. In this context, we propose-in line with the services science approach-to integrate business modeling with process modeling in order to make the transformation from business services to Web services more transparent.
Personalized online tourism services play a crucial role for tourists. In order to deliver adequate information, a semantic matching between tourism services and user context is needed. In the phase of trip planning, the essential user context comprises primarily user preferences and interests, while during the trip location and time context are added. While being on the move, unexpected events might force tourists to completely reschedule their travel plan and look for alternatives. In order to facilitate semantic matching between alternative touristic sites and user context, a specific vocabulary for the tourism domain, user type, time and location is needed. We demonstrate in this paper that existing tourism ontologies can hardly fulfill this goal as they mainly focus on domain concepts. The goal of this paper is to provide an alternative approach for covering the semantic space of tourism through the integration of modularized ontologies, such as user, W3C Time or W3C Geo, that center around a core domain ontology for the tourism sector.
Abstract. Location-based systems in the area of tourism, so-called mobile tourist guides, combine geographic information and tourism information in order to deliver relevant content to tourists on the spot. Existing systems often adhere to a heavy-weight approach. This means that, firstly, some do not build on existing tourism information systems, secondly, most of them do not employ standards for accessing geographical information systems, and thirdly, the majority employ a thick client. To tackle these issues, we propose a lightweight approach for location based systems. A major focus is on configurability, allowing to easily making existing tourism information location-aware, by pinpointing points of interest to geographical positions on a map. To demonstrate the applicability of the framework, a prototype of a mobile tourist guide has been implemented for the city of Linz, Austria, which delivers geographic data in form of maps or aerial photos and information about local points of interest.
