This volume collects the selected papers presented at the 12th International Baltic Conference on Databases and Information Systems 2016 (DB&IS 2016). The conference was held on July 4–6, 2016 in Riga, Latvia. The DB&IS 2016 continued the DB&IS series of biennial conferences, which have been held in Trakai (1994), Tallinn (1996, 2002, 2008, 2014), Riga (1998, 2004, 2010), and Vilnius (2000, 2006, 2012). Doctoral Consortium also accompanies the conference. IOS Press has been a partner of the conference for years, and selected papers are published as volumes in the book series Frontiers in Artificial Intelligence and Applications (FAIA).
During this period, the DB&IS conference has become an international forum for researchers and developers in the field of databases, information systems, and related areas. The conference features original research and application papers on the theory, design, and implementation of today's information systems. Since the conference is popular among researchers of Baltic countries, papers represent the most popular research fields regarding information systems.
The DB&IS 2016 was organized by the Faculty of Computing, University of Latvia. The International Programme Committee had 56 representatives from 21 countries all over the world. This year, 62 submissions from 16 countries were received. At least three reviewers evaluated each conference paper applying the single-blind type of peer review. Accepted papers were published in the volume of Communications in Computer and Information Science (CCIS) printed by Springer and in the journal Baltic Journal of Modern Computing (BJMC) before the conference. After the conference, the editors of this book selected improved versions of 25 papers for publishing in this volume of the FAIA.
The accepted papers span a wide spectrum of topics related to the development of information systems and data processing. The most significant topics covered by the conference are following: the development of ontology applications; tools, technologies, and languages for model-driven development; decision support systems and data mining; natural language processing and building linguistic components for information systems; advanced systems and technologies related to IS and databases, information technologies in teaching and learning.
