Propuesta de ontología para puntos de interés turístico

El presente trabajo constituye el Proyecto Final de Máster correspondiente a los estudios del Máster Oficial en Software Libre de la Universitat Oberta de Catalunya. Consiste básicamente en la elaboración y discusión de una ontología para definir puntos de interés turístico (POI). Después de una introducción y una breve exposición del alcance y metodología del trabajo, se expone la actual situación de la Web Semántica y su relación con el ámbito turístico. A continuación se describe la ontología creada, discutiendo las diferentes alternativas para cada uno de sus elementos y comparando las soluciones propuestas con otras ontologías de uso en el sector. Finalmente, se evalúan algunos ejemplos de puntos de interés turístico reales formalizados mediante esta ontología y se discuten algunas conclusiones.

BioSWR - Semantic Web services Registry for Bioinformatics

Article About the Authors Metrics Comments Related Content Abstract Introduction Functionality Implementation Discussion Acknowledgments Author Contributions References Reader Comments (0) Figures Abstract Despite of the variety of available Web services registries specially aimed at Life Sciences, their scope is usually restricted to a limited set of well-defined types of services. While dedicated registries are generally tied to a particular format, general-purpose ones are more adherent to standards and usually rely on Web Service Definition Language (WSDL). Although WSDL is quite flexible to support common Web services types, its lack of semantic expressiveness led to various initiatives to describe Web services via ontology languages. Nevertheless, WSDL 2.0 descriptions gained a standard representation based on Web Ontology Language (OWL). BioSWR is a novel Web services registry that provides standard Resource Description Framework (RDF) based Web services descriptions along with the traditional WSDL based ones. The registry provides Web-based interface for Web services registration, querying and annotation, and is also accessible programmatically via Representational State Transfer (REST) API or using a SPARQL Protocol and RDF Query Language. BioSWR server is located at http://inb.bsc.es/BioSWR/and its code is available at https://sourceforge.net/projects/bioswr/​under the LGPL license.

Personalized touristic routes implementing semantic web on GIS

Nowadays, when a user is planning a touristic route is very difficult to find out which are the best places to visit. The user has to choose considering his/her preferences due to the great quantity of information it is possible to find in the web and taking into account it is necessary to do a selection, within small time because there is a limited time to do a trip. In Itiner@ project, we aim to implement Semantic Web technology combined with Geographic Information Systems in order to offer personalized touristic routes around a region based on user preferences and time situation. Using ontologies it is possible to link, structure, share data and obtain the result more suitable for user's preferences and actual situation with less time and more precisely than without ontologies. To achieve these objectives we propose a web page combining a GIS server and a touristic ontology. As a step further, we also study how to extend this technology on mobile devices due to the raising interest and technological progress of these devices and location-based services, which allows the user to have all the route information on the hand when he/she does a touristic trip. We design a little application in order to apply the combination of GIS and Semantic Web in a mobile device.

Building a usable and accessible semantic web interaction platform

Semantic Web applications take off is being slower than expected, at least with respect to “real-world” applications and users. One of the main reasons for this lack of adoption is that most Semantic Web user interfaces are still immature from the usability and accessibility points of view. This is due to the novelty of these technologies, but this also motivates the exploration of alternative interaction paradigms, different from the “traditional” Web or Desktop applications ones. Our proposal is realized in the Rhizomer platform, which explores the possibilities of the object–action interaction paradigm at the Web scale. This paradigm is well suited for heterogeneous resource spaces such as those common in the Semantic Web. Resources, described by metadata, correspond to the objects in the paradigm. Semantic web services, which are dynamically associated to these objects, correspond to the actions. The platform is being put into practice in the context of a research project in order to build an open application for media distribution based on Semantic Web technologies. Moreover, its usability and accessibility have been evaluated in this real setting and compared to similar systems.

Arquitectura corporativa de web services

Este proyecto consiste en la realización de un sistema informático que se encargue de ampliar la red comercial de una compañía de seguros a través de Internet. Para ello se utiliza la tecnología de web services, que nos permite efectuar transacciones de datos de manera rápida, fiable y segura. El web service que se ha diseñado se encarga de resolver y dar respuesta tanto a peticiones de solicitud de precios como de emisión de pólizas en varios ramos. El objetivo es ofrecer al cliente final un método sencillo y próximo de cotización y emisión de seguros.

Estudi de com OWL amplia la funcionalitat d' RDF i aquest, a la vegada d' XML.

L'objectiu general d'aquest treball és conèixer el concepte de web semàntica i aprofundir-hi, i també entendre els principis bàsics d'algunes de les tecnologies en què recolza: les ontologies, l'XML, l'RDF i l'OWL.

Aplicativo web para la corrección de modelos UML/OCL

Introducció d'un entorn virtual d' autoaprenentatge que permeti als estudiants millorar les seves habilitats de modelització, una peça clau en la seva capacitació com a professionals de la informàtica adaptats a les demandes de la societat actual.

XML i Web Semàntica

En aquest treball es realitza una descripció dels llenguatges que constitueixen la base de la construcció de la Web Semàntica: l'XML, l'RDF i l'OWL. En concret, es realitza un estudi de la base de dades lèxica WordNet. Finalment, es presenta el disseny i la implementació d'una ontologia per representar les relacions lèxiques dels mots del català. A partir d'aquesta ontologia es crea una petita base de dades basada en la temàtica dels animals de companyia. Aquest cas pràctic permet extreure conclusions sobre els avantatges d'introduir metadades en els documents electrònics, i sobre les facilitats que ofereixen les aplicacions actuals pel desenvolupament d'aquest tipus de documents.

An Ontology for Open Rubric Exchange on the Web

While the Internet has given educators access to a steady supply of Open Educational Resources, the educational rubrics commonly shared on the Web are generally in the form of static, non-semantic presentational documents or in the proprietary data structures of commercial content and learning management systems.With the advent of Semantic Web Standards, producers of online resources have a new framework to support the open exchange of software-readable datasets. Despite these advances, the state of the art of digital representation of rubrics as sharable documents has not progressed.This paper proposes an ontological model for digital rubrics. This model is built upon the Semantic Web Standards of the World Wide Web Consortium (W3C), principally the Resource Description Framework (RDF) and Web Ontology Language (OWL).
