The International Conference on Enabling Technologies: Infrastructure for Collaborative Enterprises WETICE is an international forum for state-of-the-art research in enabling technologies for collaboration. The 26th WETICE edition will be held on June 21-23, 2017 in Poznan, Poland. In this edition, WETICE will start the second quarter of century of scientific excellence, academic and industrial success. The longevity of WETICE demonstrates its undeniable success in the scientific and academic community. A unique program is being prepared for WETICE 2017 edition. What sets WETICE apart from larger conferences is that the conference tracks are kept small enough to promote fruitful discussions on the latest technology developments, directions, problems, and requirements. Each track includes paper presentations and group discussions, while the keynote speaches and summary of discussions take place in plenary sessions.WETICE welcomes papers on “work-in-progress” from the Ph.D. students. All papers are refereed by the Program Committee of each conference track.
