The 4th Brazilian Conference on Intelligent Systems (BRACIS),
the  XII Encontro Nacional de Inteligência Artificial e Computacional (ENIAC)
and the X Brazilian Symposium in Information and Human Language Technology (STIL)
will be held November 4-7, 2015, at the Federal University of Rio Grande
do Norte (UFRN), in Natal, RN, Brazil.

The Brazilian Conference on Intelligent System (BRACIS) originated
from the combination of the two most important scientific events in
Brazil in Artificial Intelligence (AI) and Computational Intelligence
(CI): the Brazilian Symposium on Artificial Intelligence – SBIA (21
editions), and the Brazilian Symposium on Neural Networks – SBRN (12
editions).

The Encontro Nacional de Inteligência Artificial e Computacional
(ENIAC) is a national forum for researchers, practitioners, educators
and students to present and discuss innovations, trends, experiences,
developments and work in progress in the fields of Artificial and
Computational Intelligence.

The Brazilian Symposium in Information and Human Language Technology (STIL)
is a multidisciplinary conference covering a broad spectrum of disciplines
related to Human Language Technology, such as Linguistics, Computer Science,
Psycholinguistics, Information Science, among others. It aims at bringing together
both academic and industrial participants working on those areas.

As in 2014, the 2015 editions of BRACIS and ENIAC will be organized as
a joint event, with the goal of promoting research in Intelligent
Systems and scientific exchange among researchers, practitioners,
scientists, and engineers in Artificial and Computational intelligence
as well as in related fields. Being a biannual event, STIL will once again
join BRACIS as a colocated event as it did in its latest editions.
