    Consuming post-disaster destinations: The case of Sichuan, China

    Get PDF
    Addressing the call for a better understanding of tourist behavior in relation to post-disaster destinations, this study explores the motivations and intentions of potential domestic tourists (from non-hit areas) to visit Sichuan, China in the aftermath of an earthquake. Drawing on dark tourism theories, this study offers a more comprehensive insight into the consumption of post-disaster destinations, aiming to capture the impact of the changes to the destination’s attributes on tourist behavior. The findings move beyond the common approach to tourism recovery, which solely focuses on reviving the traditional ‘‘non-dark’’ products. This study reveals the importance of newly formed dark attributes that emerge from the disaster as another means to destination recovery, reflected in the emergence of new tourist segments

    [ES] La monitorización de la ejecución de un plan es crucial para un agente autónomo que realiza su labor en un entorno dinámico, pues influye en su capacidad de reaccionar ante los cambios. Mientras ejecuta su plan puede sufrir un fallo y, en su esfuerzo por solucionarlo, puede interferir sin saberlo con otros agentes que operan en su mismo entorno. Por otra parte, para actuar racionalmente es necesario que el agente sea consciente del contexto y pueda recopilar y ampliar su información a partir de lo que percibe para poder compensar su conocimiento previo parcial o incorrecto del problema y lograr el mejor resultado posible ante las nuevas situaciones que aparecen. El trabajo realizado en esta tesis permite a los agentes autónomos ejecutar sus planes en un entorno dinámico y adaptarse a eventos inesperados y circunstancias desconocidas. Pueden utilizar su percepción del contexto para proporcionar respuestas deliberativas conscientes y ser capaces así de aprovechar las oportunidades que surgen o reparar los fallos sin perturbar a otros agentes. Este trabajo se centra en el desarrollo de una arquitectura independiente del dominio capaz de manejar las necesidades de agentes con este tipo de comportamiento autónomo. Los tres pilares de la arquitectura propuesta los forman el sistema inteligente para la simulación de la ejecución en entornos dinámicos, la adquisición de conocimiento consciente del contexto para ampliar la base de datos del agente y la reparación de planes ante fallos u oportunidades tratando de interferir lo mínimo con los planes de otros agentes. El sistema inteligente de simulación de la ejecución permite al agente representar el plan en una línea de tiempo, actualizar periódicamente su estado interno con información del mundo real y disparar nuevos eventos en momentos concretos. Los eventos se procesan en el contexto del plan; si se detecta un error, el simulador reformula el problema de planificación, invoca de nuevo al planificador y reanuda la ejecución. El simulador es una aplicación de consola y ofrece una interfaz gráfica diseñada específicamente para una aplicación inteligente de turismo. El módulo de adquisición de conocimiento sensible al contexto utiliza operaciones semánticas para aumentar dinámicamente la lista predefinida de tipos de objetos de la tarea de planificación con nuevos tipos relevantes. Esto permite que el agente sea consciente de su entorno, enriquezca el modelo de su tarea y pueda razonar a partir de un conocimiento incompleto. Con todo esto se consigue potenciar la autonomía del sistema y la conciencia del contexto. La novedosa estrategia de reparación de planes le permite a un agente reparar su plan al detectar un fallo de manera responsable con el resto de agentes que comparten su mismo entorno de ejecución. El agente utiliza una nueva métrica, el compromiso del plan, como función heurística para guiar la búsqueda hacia un plan solución comprometido con el plan original, en el sentido de que se trata de respetar los compromisos adquiridos con otros agentes al mismo tiempo que se alcanzan los objetivos originales. En consecuencia, la comunidad de agentes sufrirá menos fallos por cambios bruscos en el entorno o requerirá menos tiempo para ejecutar las acciones correctoras si el fallo es inevitable. Estos tres módulos han sido desarrollados y evaluados en varias aplicaciones como un asistente turístico, una agencia de reparación de electrodomésticos y un asistente del hogar.[CA] El monitoratge de l'execució d'un pla és crucial per a un agent autònom que realitza la seua labor en un entorn dinàmic, perquè influeix en la seua capacitat de reaccionar davant els canvis. Mentre executa el seu pla pot patir una fallada i, en el seu esforç per solucionar-lo, pot interferir sense saber-ho amb altres agents que operen en el seu mateix entorn. D'altra banda, per a actuar racionalment és necessari que l'agent siga conscient del context i puga recopilar i ampliar la seua informació a partir del que percep per a poder compensar el seu coneixement previ parcial o incorrecte del problema i aconseguir el millor resultat possible davant les noves situacions que apareixen. El treball realitzat en aquesta tesi permet als agents autònoms executar els seus plans en un entorn dinàmic i adaptar-se a esdeveniments inesperats i circumstàncies desconegudes. Poden utilitzar la seua percepció del context per a proporcionar respostes deliberatives conscients i ser capaces així d'aprofitar les oportunitats que sorgeixen o reparar les fallades sense pertorbar a altres agents. Aquest treball se centra en el desenvolupament d'una arquitectura independent del domini capaç de manejar les necessitats d'agents amb aquesta mena de comportament autònom. Els tres pilars de l'arquitectura proposada els formen el sistema intel·ligent per a la simulació de l'execució en entorns dinàmics, l'adquisició de coneixement conscient del context per a ampliar la base de dades de l'agent i la reparació de plans davant fallades o oportunitats tractant d'interferir el mínim amb els plans d'altres agents. El sistema intel·ligent de simulació de l'execució permet a l'agent representar el pla en una línia de temps, actualitzar periòdicament el seu estat intern amb informació del món real i disparar nous esdeveniments en moments concrets. Els esdeveniments es processen en el context del pla; si es detecta un error, el simulador reformula el problema de planificació, invoca de nou al planificador i reprén l'execució. El simulador és una aplicació de consola i ofereix una interfície gràfica dissenyada específicament per a una aplicació intel·ligent de turisme. El mòdul d'adquisició de coneixement sensible al context utilitza operacions semàntiques per a augmentar dinàmicament la llista predefinida de tipus d'objectes de la tasca de planificació amb nous tipus rellevants. Això permet que l'agent siga conscient del seu entorn, enriquisca el model de la seua tasca i puga raonar a partir d'un coneixement incomplet. Amb tot això s'aconsegueix potenciar l'autonomia del sistema i la consciència del context. La nova estratègia de reparació de plans li permet a un agent reparar el seu pla en detectar una fallada de manera responsable amb la resta d'agents que comparteixen el seu mateix entorn d'execució. L'agent utilitza una nova mètrica, el compromís del pla, com a funció heurística per a guiar la cerca cap a un pla solució compromés amb el pla original, en el sentit que es tracta de respectar els compromisos adquirits amb altres agents al mateix temps que s'aconsegueixen els objectius originals. En conseqüència, la comunitat d'agents patirà menys fallades per canvis bruscos en l'entorn o requerirà menys temps per a executar les accions correctores si la fallada és inevitable. Aquests tres mòduls han sigut desenvolupats i avaluats en diverses aplicacions com un assistent turístic, una agència de reparació d'electrodomèstics i un assistent de la llar.[EN] Execution Monitoring is crucial for the success of an autonomous agent executing a plan in a dynamic environment as it influences its ability to react to changes. While executing its plan in a dynamic world, it may suffer a failure and, in its endeavour to fix the problem, it may unknowingly disrupt other agents operating in the same environment. Additionally, being rational requires the agent to be context-aware, gather information and extend what is known from what is perceived to compensate for partial or incorrect prior knowledge and achieve the best possible outcome in various novel situations. The work carried out in this PhD thesis allows the autonomous agents executing a plan in a dynamic environment to adapt to unexpected events and unfamiliar circumstances, utilise their perception of context and provide context-aware deliberative responses for seizing an opportunity or repairing a failure without disrupting other agents. This work is focused on developing a domain-independent architecture capable of handling the requirements of such autonomous behaviour. The architecture pillars are the intelligent system for execution simulation in a dynamic environment, the context-aware knowledge acquisition for planning applications and the plan commitment repair. The intelligent system for execution simulation in a dynamic environment allows the agent to transform the plan into a timeline, periodically update its internal state with real-world information and create timed events. Events are processed in the context of the plan; if a failure occurs, the simulator reformulates the planning problem, reinvokes a planner and resumes the execution. The simulator is a console application and has a GUI designed specifically for smart tourism. The context-aware knowledge acquisition module utilises semantic operations to dynamically augment the predefined list of object types of the planning task with relevant new object types. This allows the agent to be context-aware of the environment and the task and reason with incomplete knowledge, boosting the system's autonomy and context-awareness. The novel plan commitment repair strategy among multiple agents sharing the same execution environment allows the agent to repair its plan responsibly when a failure is detected. The agent utilises a new metric, plan commitment, as a heuristic to guide the search for the most committed repair plan to the original plan from the perspective of commitments made to other agents whilst achieving the original goals. Consequently, the community of agents will suffer fewer failures due to the sudden changes or will have less lost time if the failure is inevitable. All these developed modules were investigated and evaluated in several applications, such as a tourist assistant, a kitchen appliance repair agency and a living home assistant.Babli, M. (2023).

    Semantic discovery and reuse of business process patterns

    Get PDF
    Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse

    A Software Product Line Approach to Ontology-based Recommendations in E-Tourism Systems

    Get PDF
    This study tackles two concerns of developers of Tourism Information Systems (TIS). First is the need for more dependable recommendation services due to the intangible nature of the tourism product where it is impossible for customers to physically evaluate the services on offer prior to practical experience. Second is the need to manage dynamic user requirements in tourism due to the advent of new technologies such as the semantic web and mobile computing such that etourism systems (TIS) can evolve proactively with emerging user needs at minimal time and development cost without performance tradeoffs. However, TIS have very predictable characteristics and are functionally identical in most cases with minimal variations which make them attractive for software product line development. The Software Product Line Engineering (SPLE) paradigm enables the strategic and systematic reuse of common core assets in the development of a family of software products that share some degree of commonality in order to realise a significant improvement in the cost and time of development. Hence, this thesis introduces a novel and systematic approach, called Product Line for Ontology-based Tourism Recommendation (PLONTOREC), a special approach focusing on the creation of variants of TIS products within a product line. PLONTOREC tackles the aforementioned problems in an engineering-like way by hybridizing concepts from ontology engineering and software product line engineering. The approach is a systematic process model consisting of product line management, ontology engineering, domain engineering, and application engineering. The unique feature of PLONTOREC is that it allows common TIS product requirements to be defined, commonalities and differences of content in TIS product variants to be planned and limited in advance using a conceptual model, and variant TIS products to be created according to a construction specification. We demonstrated the novelty in this approach using a case study of product line development of e-tourism systems for three countries in the West-African Region of Africa

    A Spatial Agent-Based Model to Explore Scenarios of Adaptation to Climate Change in an Alpine Tourism Destination

    A vast body of literature suggests that the European Alpine region may be one of the most sensitive to climate change impacts. Adaptation to climate change of Alpine socio-ecosystems is increasingly becoming an issue of interest for the scientific community while the people of the Alps are often unaware of or simply ignore the problem. ClimAlpTour is a European research project of the Alpine Space Programme, bringing together institutions and scholars from all countries of the Alpine arch, in view of dealing with the expected decrease in snow and ice cover, which may lead to a rethinking of tourism development beyond the traditional vision of winter sports. The research reported herein analyses the municipality of Auronzo di Cadore (22,000 ha) in the Dolomites under the famous peaks of the “Tre Cime di Lavaredo”. The local economy depends on tourism which is currently focused on the summer season, while the winter season is weak. As a whole, the destination receives approximately 65,000 guests per year with a resident population of 3,600 inhabitants. Since recently the Community Council is considering options on how to stimulate a further development of the winter tourism. This paper refers to a prototype agent-based model, called AuronzoWinSim, for the assessment of alternative scenarios of future local development strategies, taking into account complex spatial and social dynamics and interactions. Different typologies of winter tourists compose the set of human agents. Climate change scenarios are used to produce temperature and snow cover projections. The model is mainly informed by secondary sources, including demographic and economic time series, and biophysical data which feed-in its spatial dimension. Primary data from field surveys are used to calibrate the main parameters. AuronzoWinSim is planned for use in a participatory context with groups of local stakeholders.Alpine Winter Tourism, Spatial Agent-Based Model, Climate Change Adaptation

    A review of the role of sensors in mobile context-aware recommendation systems

    Get PDF
    Recommendation systems are specialized in offering suggestions about specific items of different types (e.g., books, movies, restaurants, and hotels) that could be interesting for the user. They have attracted considerable research attention due to their benefits and also their commercial interest. Particularly, in recent years, the concept of context-aware recommendation system has appeared to emphasize the importance of considering the context of the situations in which the user is involved in order to provide more accurate recommendations. The detection of the context requires the use of sensors of different types, which measure different context variables. Despite the relevant role played by sensors in the development of context-aware recommendation systems, sensors and recommendation approaches are two fields usually studied independently. In this paper, we provide a survey on the use of sensors for recommendation systems. Our contribution can be seen from a double perspective. On the one hand, we overview existing techniques used to detect context factors that could be relevant for recommendation. On the other hand, we illustrate the interest of sensors by considering different recommendation use cases and scenarios
