This open access book is a timely contribution in presenting recent issues, approaches, and results that are not only central to the highly interdisciplinary field of concept research but also particularly important to newly emergent paradigms and challenges.The contributors present a unique, holistic picture for the understanding and use of concepts from a wide range of fields including cognitive science, linguistics, philosophy, psychology, artificial intelligence, and computer science.The chapters focus on three distinct points of view that lie at the core of concept research: representation, learning, and application.The contributions present a combination of theoretical, experimental, computational, and applied methods that appeal to students and researchers working in these fields.
