Research Areas

The Research Group on Distributed Information Systems (SID) work on systems that help people to find the data or information they need, using semantic technology (ontologies) and data services in mobile environments. Thus, we can define two main research areas in which we work: semantic information systems and data management on mobile computing environments. We also stress that some of the systems developed belong to both research areas, as they apply semantic techniques to access to data in wireless environments.



This research area focuses on the study and development of techniques to facilitate the access to data for a specific search of information on the Web or other types of data sources (for example, relational databases). Through the use of semantic technologies, such as ontologies, reasoners based on description Logics, etc. The aim is to determine the semantic meaning of the available data to provide users with the necessary information that fulfils their needs.

This research area focuses on the study and development of relevant data management techniques for users in dynamic mobile computing environments. This includes the development of software architectures for location-based services (Location-Based Services or LBSs), data management in vehicular networks, mobile agent technology, and management of data streams (for example, sensor data).

Some of the systems that we have created use the semantic information management techniques that we have developed and apply them in the field of data management in wireless environments, building in this way semantic data services for the mobile computing area.

Objetivos: In this project we aim to increase the uptake of language technologies by exploiting the combination of linked data and language technologies, that is Linguistic Linked Open Data (LLOD), to create ready-to-use multilingual data. Prêt-à-LLOD aims to achieve this by creating a new methodology for building data value chains applicable to a wide-range of sectors and applications and based around language resources and language technologies that can be integrated by means of semantic technologies, in particular the usage of Linguistic Linked Open Data (LLOD).
