Review "This timely and important book provides lucid, provocative, and comprehensive coverage of essential topics related to ontologies and their critical applications in bioinformatics. Written by leading experts in the field, the book is readable and highly informative. It is highly recommended for undergraduate and graduate students in biology, computer science, and medicine, as well as for researchers interested in bioinformatics and genomic science." --Yi Pan, Chair and Professor, Department of Computer Science, Georgia State University, Editor-in-Chief, International Journal of Bioinformatics Research and Applications "Given the current explosion of biological data in multiple dimensions, it is time to think systematically about strategies and techniques to not only store, but also integrate and represent them in knowledge-oriented ways. Ontology is the solution, and this book is an excellent effort to evaluate a number of alternative ontology-exchange languages, and to recommend them for use within the larger bioinformatics community." --Bo Yuan, Departments of Biomedical Informatics and Pharmacology, The Ohio State University Product Description Recent advances in biotechnology, spurred by the Human Genome Project, have resulted in the accumulation of vast amounts of new data. Ontologies -- computer-readable, precise formulations of concepts (and the relationship among them) in a given field -- are a critical framework for coping with the exponential growth
