This volumeincludes extended and revised versions of the papers presented at the 4thWorkshop on “Combinations of Intelligent Methods and Applications” (CIMA 2014) whichwas intended to become a forum for exchanging experience and ideas amongresearchers and practitioners dealing with combinations of differentintelligent methods in Artificial Intelligence. The aim is to create integratedor hybrid methods that benefit from each of their components. Some of theexisting presented efforts combine soft computing methods (fuzzy logic, neuralnetworks and genetic algorithms). Another stream of efforts integrates case-basedreasoning or machine learning with soft-computing methods. Some of thecombinations have been more widely explored, like neuro-symbolic methods,neuro-fuzzy methods and methods combining rule-based and case-based reasoning. CIMA 2014 was held in conjunction with the 26th IEEE InternationalConference on Tools with Artificial Intelligence (ICTAI2014).
