WCPR 2014 Chairs’ Welcome
It is our great pleasure to welcome you to the 2014 ACM Multi Media - Workshop on
Computational Personality Recognition (WCPR’14). This is the second edition of the WCPR and
we are really glad to be hosted in a great conference like ACMMM. After a first successful
edition, this year’s symposium continues its tradition of allowing participants to run experiments
on personality recognition on the same benchmarks. We believe that the research results, including
models, systems, applications, and theoretical findings, together with the experience reports on
leading edge issues in the emerging field of personality recognition, will be extremely significant
for future research. In particular, the mission of the WCPR is to share data and tools, that will
make easier the comparison of the results for future systems and applications in personality
recognition. The WCPR’14 gives researchers and practitioners a unique opportunity to compete
with their systems or prototypes for personality recognition from text and multimedia signals.
The call for papers attracted many submissions, in particular from Europe and United States. The
program committee accepted 6 papers that cover a variety of topics, including feature selection,
application of new and old resources, and evaluation of algorithms for the automatic prediction of
personality types.
Putting together WCPR’14 was a team effort. We first thank the authors for providing the content of
the program. We are grateful to the program committee, who worked very hard in reviewing papers
and providing feedback for authors. Finally, we thank the hosting organization, the sponsors, and our
generous supporters, University of Trento, Fondazione Bruno Kessler (FBK) and IDIAP Research
Institute.
We hope that you will find this program interesting and thought-provoking and that the
symposium will provide you with a valuable opportunity to share ideas with other researchers and
scholars from institutions around the world.
