The book "Soft Computing in Ontologies and Semantic Web" offers a comprehensive analysis of the rapidly growing areas of soft computing techniques and their applications in the context of ontologies and the Semantic Web. It addresses various methods such as fuzzy logic, genetic algorithms, neural networks, rough sets, and Bayesian networks. The author, Zongmin Ma, demonstrates how the components of the Semantic Web, including RDF, description languages, and ontologies, can be supported through a soft computing approach. The aim of the book is to provide a consolidated representation of current studies and to deliver valuable information to researchers, practitioners, and students in the field of web intelligence. It is also aimed at IT professionals who are faced with non-traditional applications where conventional approaches reach their limits.
