ITAT 2016 Main Track The main track of the ITAT conference accepts contributions in all areas of computer science. Since 2013, the conference also features specialized thematic workshops in several topics previously repre- sented in the main track of the conference. As the focus of the conference shifts to these workshops, the number of submission to the main track decreases. This year the main track had six submissions, four of which were accepted based on anonymous reviews from at least two independent members of the program committee. I would like to thank to the authors of the submitted papers and to all program committee members for their contribution to the ITAT conference.
