following five sections: logic and reasoning; knowledge-based systems
and multi-agent systems; natural language processing; machine
translation and bioinformatics and medical applications. The second
volume deals with advances in soft computing and its applications and is
structured in the following eight sections: evolutionary and
nature-inspired metaheuristic algorithms; neural networks and hybrid
intelligent systems; fuzzy systems; machine learning and pattern
recognition; data mining; computer vision and image processing;
robotics, planning and scheduling and emotion detection, sentiment
