OEG's members have developed the mIO! ontology network. The aim of this network is to improve the mobile phone user experience, enabling the terminal to be used as a more reliable source of contextual information related to user tastes and preferences, social relations, services and environment.
The ontology network includes local information on the user (position, date), environment (temperature, luminosity), entertainment (theatre, sport), and social information (list of friends, agenda). It also includes information about the services that users can produce and/or consume (availability, price), as well as on the devices they use (battery, cover).
Luis Manuel Vilches Blázquez defends his PhD thesis "Metodología para la integración basada en ontologías de la información de bases de datos heterogéneas en el dominio hidrográfico". The defense will take place on May 19th at 16:00 in the Sala de Audiovisuales of the Escuela Técnica Superior de Ingenieros de Topografía, Geodesia y Cartografía at Universidad Politécnica de Madrid.
Boris Villazón-Terrazas defends his PhD thesis "A Method for Reusing and Re-engineering Non-Ontological Resources for Building Ontologies". The defense will take place on April 14th at 10:30 in the Sala de Grados of the Facultad de Informática at Universidad Politécnica de Madrid.
The thesis is available for its download in the following link.
OGSA-DAI is a customisable framework for the management of distributed data resources - whether these be databases, files or other types of data - via web services. OGSA-DAI provides a workflow engine for the execution of data access, update, transformation, federation, processing and delivery scenarios. It also provides a powerful distributed query processor allowing SQL queries to be targeted across distributed databases.
Among other new features OGSA-DAI 4.1 now supports RDF data resources which allow querying of Jena SDB databases and SPARQL endpoints using SPARQL, developed by Carlos Buil-Aranda, from the Ontology Engineering Group.
The GeoLinkedData Initiative is happy to announce the release of map4rdf. map4rdf is a mapping and faceted browsing tool for exploring and visualizing RDF datasets enhanced with geometrical Information.
We announce that Carlos Buil, member of the OEG, has developed the SPARQL-DQP system. This system implements the SPARQL 1.1 Federated Query extension, by extending the OGSA-DAI/DQP system. The optimisation of these federated queries is done in SPARQL-DQP by identifying well-designed patterns in queries. Using such patterns it is possible to apply rewriting rules to federated SPARQL queries and improve the execution time of the queries.
The code and an online demo will be soon available.
Two papers written by members of the group were presented at the International Semantic Web Conference (ISWC 2010) held in Shanghai, China from November 7th to 11th. The articles are "Semantic Techniques for Enabling Knowledge Reuse in Conceptual Modelling" by Jorge Gracia del Río and "Enabling Ontology-based Access to Streaming Data Sources" by Jean-Paul Calbimonte.
This year the Second Workshop on Ontology Patterns (WOP 2010) co-located at ISWC 2010 takes place in Shanghai (China). There, the OEG team presents some work related to ODPs research at the research papers track and the pattern session.
We are please to announce that the members of GeoLinked Data (.es) have received an honorary mention in the Triplification Challenge 2010 in the "Open Government Data" track.

We are pleased to announce that the portal has been launched GeoLinkedData.es. GeoLinked Data (.es) is an open initiative aimed at enriching the Web of Data with geospatial data of the Spanish territory. This initiative has been launched with the publication of various information sources from the National Geographic Institute, making knowledge bases available as RDF (Resource Description Framework) in accordance with the principles of Linked Data. In addition, this data is interrelated with other existing knowledge bases in the Linking Open Data. Thus, Spain is joining the initiative to other countries like Britain and Germany have recently begun.
We encourage you to take a walk through the portal.
Abstract: Semantic technologies have become widely adopted in recent years, and choosing the right technologies for the problems that users face is often a difficult task. This paper presents an application of the Analytic Network Process for the recommendation of semantic technologies, which is based on a quality model for semantic technologies. Instead of relying on expert-based comparisons of alternatives, the comparisons in our framework depend on real evaluation results. Furthermore, the recommendations in our framework derive from user quality requirements, which leads to better recommendations tailored to users' needs. This paper also presents an algorithm for pairwise comparisons, which is based on user quality requirements and evaluation results.
