Data Processing in Space, Time, and Semantics Dimensions

This work presents an experimental system for data processing in space, time and semantics dimensions using current Semantic Web technologies. The paper describes how we obtain geographic and event data from Internet sources and also how we integrate them into an RDF store. We briefly introduce a set of functionalities in space, time and semantics dimensions. These functionalities are implemented based on our existing technology for main-memory based RDF data processing developed in the LSDIS Lab. A number of these functionalities are exposed as REST Web services. We present two sample client side applications that are developed using a combination of our services with Google map service

Semantic Web: Metadata, Linked Data, Open Data

What's the Semantic Web? What's the use? The inventor of the Web Tim Berners-Lee describes it as a research methodology able to take advantage of the network to its maximum capacity. This metadata system represents the innovative element through web 2.0 to web 3.0. In this context will try to understand what are the theoretical and informatic requirements of the Semantic Web. Finally will explain Linked Data applications to develop new tools for active citizenship

A scoping review: exploring the world of medical and wellness tourism

Purpose: Medical and wellness tourism is a growing phenomenon, and tourists all over the world are traveling with the express purpose of accessing medical treatment or promoting health through physically and psychologically beneficial activities. This industry has continued to expand with the Internet’s help, as customers can now make choices that are more appropriate and informed decisions. Design: This research employed mixed content analysis methods. The qualitative approach reproduced tourists’ appraisals and assessed the spatial relationships between terms and concepts in medical and wellness tourism, with generalizable and reproducible results. Theoretical Contribution: This study specifically adds to the literature on post-experiences of medical and wellness tourism and the impact of Web-based information through reviewers’ satisfaction and willingness to recommend facilities to others. Practical Contributions: Medical tourists’ reviews indicate shared commonalities when identifying significant factors in medical services received. These individuals also focus on cost, treatment effectiveness; time spent collecting healthcare information, and recommendations they plan to offer to friends and family. Wellness tourists perceive resort facilities—including room conditions—and thalassotherapy treatments as the primary drivers of good service. Critical attributes of room condition are overall cleanliness and room comfort, especially bed, bathroom, and shower facilities. Tourists’ reviews of their experiences of thermal spa facilities provide a strategic order in which to implement service attributes by degree of influence: thermal facilities and services, hotel reception and room, food quality and price, pool and bath access, location views and accessibility, and staff’s professionalism and friendliness. Originality: The results add to the slowly growing body of literature on medical and wellness tourism and provide significant information to prospective medical tourists, healthcare service professionals, hoteliers, and other operators who become part of tourists’ total experience. This thesis identifies new themes based on semantic analyses that explored tourists’ behavior, intentions, and overall experiences shared online.Objetivo: O Turismo Médico e de Bem-Estar é um fenómeno crescente. Turistas de todo o mundo viajam com o intuito de ter acesso a tratamento médico ou de melhorar o seu estado de saúde através de atividades físicas e psicológicas que lhes sejam benéficas. Esta indústria tem vindo a crescer com ajuda da Internet, permitindo aos turistas fazer melhores escolhas e tomar decisões informadas. Desenho da tese: Este estudo tem como base a análise de conteúdos mistos. A abordagem qualitativa reproduz as avaliações dos turistas e avalia as relações entre as narrativas e os conceitos no Turismo Médico e de Bem-Estar, obtendo resultados replicáveis e generalizáveis. Contribuição teórica: Este estudo contribui com o conhecimento teórico no setor do turismo de Saúde e Bem-estar e o impacto das opiniões dos turistas nas plataformas online como veículo para expressar satisfação e recomendar serviços a outros turistas. Contribuição prática: No Turismo Médico os comentários online indicam características comuns inerentes ao tratamento médico. Como fatores determinantes no processo de decisão os turistas realçam o preço, a eficácia do tratamento, o tempo despendido na recolha de informações medicas, e partilham recomendações com amigos e familiares. No turismo de Bem-Estar os turistas percecionam as infraestruturas do resort-incluindo as condições do quarto e os tratamentos de talassoterapia como fatores determinantes de um bom serviço. Indicam como fatores críticos -o quarto- a limpeza e o conforto em particular uma cama confortável, a casa de banho e o chuveiro. Os turistas que utilizam as Termas e Spa indicam por ordem decrescente a implementação dos seguintes serviços: acesso as termas e serviços, a receção do hotel e sala, qualidade da comida e preço, piscina e banho térmico, localização, vista e acessos bem como o profissionalismo e simpatia dos colaboradores. Originalidade: Os resultados contribuem para o desenvolvimento da literatura sobre o Turismo Medico e de Bem-Estar e sugere diretrizes para potenciais turistas médicos, profissionais de saúde, setor hoteleiro e outros operadores que integram a experiência destes turistas. Com base na análise semântica esta tese identifica novas temáticas que exploram comportamentos, intenções e experiências que os turistas compartilham online

Online Popularity and Topical Interests through the Lens of Instagram

Online socio-technical systems can be studied as proxy of the real world to investigate human behavior and social interactions at scale. Here we focus on Instagram, a media-sharing online platform whose popularity has been rising up to gathering hundred millions users. Instagram exhibits a mixture of features including social structure, social tagging and media sharing. The network of social interactions among users models various dynamics including follower/followee relations and users' communication by means of posts/comments. Users can upload and tag media such as photos and pictures, and they can "like" and comment each piece of information on the platform. In this work we investigate three major aspects on our Instagram dataset: (i) the structural characteristics of its network of heterogeneous interactions, to unveil the emergence of self organization and topically-induced community structure; (ii) the dynamics of content production and consumption, to understand how global trends and popular users emerge; (iii) the behavior of users labeling media with tags, to determine how they devote their attention and to explore the variety of their topical interests. Our analysis provides clues to understand human behavior dynamics on socio-technical systems, specifically users and content popularity, the mechanisms of users' interactions in online environments and how collective trends emerge from individuals' topical interests.Comment: 11 pages, 11 figures, Proceedings of ACM Hypertext 201

Path, theme and narrative in open plan exhibition settings

Three arguments are made based on the analysis of science exhibitions. First,sufficiently refined techniques of spatial analysis allow us to model the impact oflayout upon visitors' paths, even in moderately sized open plans which allow almostrandom patterns of movement and relatively unobstructed visibility. Second, newlydeveloped or adapted techniques of analysis allow us to make a transition frommodeling the mechanics of spatial movement (the way in which movement is affectedby the distribution of obstacles and boundaries), to modeling the manner in whichmovement might register additional aspects of visual information. Third, theadvantages of such purely spatial modes of analysis extend into providing us with asharper understanding of some of the pragmatic constrains within which exhibitioncontent is conceived and designed
