This volume contains the proceedings of the 4th International Conference on Data Technologies and Applications - DATA 2015), which is sponsored by the Institute for Systems and Technologies of Information, Control and Communication (INSTICC), and co-organized by the University of Haute Alsace and held in cooperation with the ACM SIGMIS - ACM Special Interest Group on Management Information Systems
This conference brings together researchers and practitioners interested in databases, data warehousing, data mining, data management, data security and other aspects of information systems and technology involving advanced applications of data.
The high quality of the DATA 2015 program is enhanced by the three keynote lectures, delivered by distinguished speakers who are renowned experts in their fields: Michele Sebag (Laboratoire de Recherche en Informatique, CNRS, France), John Domingue (The Open University, United Kingdom) and Paul Longley (University College London, United Kingdom).
The meeting is complemented with the Special Session on Knowledge Discovery meets Information Systems: Applications of Big Data Analytics and BI - methodologies, techniques and tools (KomIS).
DATA 2015 received 70 paper submissions, including the special session, from 32 countries in all continents, of which 44% were orally presented (20% as full papers). In order to evaluate each submission, a double blind paper review was performed by the Program Committee.
The program for this conference required the dedicated effort of many people. Firstly, we must thank the authors, whose research efforts are herewith recorded. Next, we thank the members of the Program Committee and the auxiliary reviewers for their diligent and professional reviewing. We would also like to deeply thank the invited speakers for their invaluable contribution and for taking the time to prepare their talks. Finally, a word of appreciation for the hard work of the INSTICC team; organizing a conference of this level is a task that can only be achieved by the collaborative effort of a dedicated and highly capable team.
A successful conference involves more than paper presentations; it is also a meeting place, where ideas about new research projects and other ventures are discussed and debated. Therefore, a social event & banquet has been arranged for the evening of July 21st (Tuesday) in order to promote this kind of social networking.
We wish you all an exciting conference and an unforgettable stay in the city of Colmar. We hope to meet you again next year at DATA 2016 in Lisbon, Portugal.
