These
transactions publish research in computer-based methods of computational
collective intelligence (CCI) and their applications in a wide range of fields
such as the semantic Web, social networks, and multi-agent systems. TCCI
strives to cover new methodological, theoretical and practical aspects of CCI
understood as the form of intelligence that emerges from the collaboration and competition
of many individuals (artificial and/or natural). The application of multiple
computational intelligence technologies, such as fuzzy systems, evolutionary
computation, neural systems, consensus theory, etc., aims to support human and
other collective intelligence and to create new forms of CCI in natural and/or
artificial systems. This nineteenth issue contains 11 carefully selected and
revised contributions.
