Welcome to the 2015 edition of Terminology and Artificial Intelligence (TIA 2015). This year the conference will be held on November 4-6 in the historical city of Granada, Spain. It will be the first edition of TIA outside France. We have received a wide range of submissions. Each submission was assigned to at least three reviewers and acceptance decisions were based on the reviews and the expertise of the programme committee. We finally accepted 16 long papers, 5 short papers and 4 posters and demonstrations. Authors of long and short papers also had the possibility to present their systems during a demo session. This year we had the privilege of coordinating the conference. This has been a very enriching experience and we had the chance to work with a very efficient group of people who did an amazing job to make everything run smoothly. The local organization team was led by Pamela Faber and included Pilar Le´on Arau´z, Beatriz S´anchez C´ardenas, Arianne Reimerink, Silvia Montero Mart´ınez, Miguel Vega Exp´osito, and Ana Bel´en Pelegrina Ortiz, all from the University of Granada. Finally, we would like to thank the authors of submitted and accepted papers, and all the attendees to the conference, who will be the main actors from November 4 to November 6, 2015. We are convinced that we will experience a fantastic conference, scientifically exciting and full of fond memories, in the unique environment of Granada.
