How do we form categories? What is the role of similarity in categorization? Can we formalize the answers to these questions to derive further insights and develop useful software systems? These were the questions addressed at an interdisciplinary meeting attended by psychologists, computer scientists, anthropologists, statisticians, and philosophers held at the University of Edinburgh. The edited volume Similarity and Categorization arises from this meeting. The publication of Similarity and Categorization is timely because the study of categorization is at a theoretical crossroads.
