Jordi Conesa is an associate professor of computer science at the Universitat Oberta de Catalunya. He received his PhD in software engineering from the Technical University of Catalonia, after a research stay in Georgia State University of Atlanta (US). His research interest concerns the areas of conceptual modelling, ontologies, semantic web, knowledge-based systems, and e-learning. His long-term goal is to develop methodologies and tools to use ontologies effectively in several application domains, such as conceptual modelling, software engineering, and e-learning. He has authored more than 60 research papers, has participated in several research projects, including EU-FP7, CICYT and AVANZA funded projects, and has contributed in the organization of international conferences and has been program chair and program committee member of several international conferences. Finally, he also serves as external reviewer for many conferences and journals. Dr. Antoni Pérez-Navarro has a PhD in Physics from the Universitat Autonoma de Barcelona and Is graduated in Physics from the same university. His research domain is mainly focused in location bases systems (LBS) and context aware recommendation systems, outdoors as well as indoors, and its applications mainly to health and tourism. He has worked as physics and geographic information systems lecturer at several institutions: Universitat Oberta de Catalunya UOC, Universitat Autònoma de Barcelona, Escola Universitària Salesiana de Sarrià and Institut Cartogràfic de Catalunya. He has also 5 years of experience as project manager in a GIS company, Aurensis, S.L. His main research interests are indoor positioning and prevention of deseases via smartphones. He has lead the project Itiner@ where a Context Aware Recommender System was created. Regarding education, his main contributions are mathematical notation in physics and mathematics in online environments; and the introduction of video as a learning tool in the virtual classroom, which received the Best Innovation Project Award at UOC in 2010 with the project Present@. He has published over 12 articles in journals indexed in ISI-JCR and has supervided over 14 MSc theses already completed. Nowadays he is supervising three PhD Thesis He holds a Bachelor’s Degree in Computer Science (2003) and a PhD with distinction (2011), both from Universitat Jaume I. His main research interests are in the areas of Indoor Positioning and Navigation, Wi-Fi fingerprinting, Machine Learning, Pattern Recognition, Multiple Classifier Systems, Sensor Fusion, Knowledge-based Systems and Interoperability. As a result of his work, during the last years, he published over 70 research contributions as books, book chapters, international journals and conference papers, he served as a reviewer in different international journals and conferences, has participated in 10 different research projects, and advised 1 Phd student. He holds a Bachelor’s Degree in Computer Science (1998) and a PhD with distinction (2008), both from Universitat Jaume I. His current research interests include indoor localization and navigation, human and social behavior from sensor data, sport video analysis and surveillance applications. As a result of his work, during the last years, he published over 45 research contributions as books, book chapters, international journals and conference papers, he served as a reviewer in different international journals and conferences, has participated in 10 different research projects, and advised 2 Phd student.
