Practical Ontologies for Information Professionals provides an accessible introduction and exploration of ontologies and demonstrates their value to information professionals.
More data and information is being created than ever before. Ontologies, formal representations of knowledge with rich semantic relationships, have become increasingly important in the context of today’s information overload and data deluge. The publishing and sharing of explicit explanations for a wide variety of concepts, in a machine readable format, has the power to both improve information retrieval and discover new knowledge. Information professionals are key contributors to the development of new, and increasingly useful, ontologies.
Practical Ontologies for Information Professionals provides an accessible introduction to the following:
Readership: This book will be essential reading for information professionals in libraries and other cultural heritage institutions who work with digitization projects, cataloguing and classification and information retrieval. It will also be useful to LIS students who are new to the field.
1. What is an ontology?
2. Ontologies and the semantic web
3. Existing ontologies
4. Adopting ontologies
5. Building ontologies
6. Interrogating ontologies
7. The future of ontologies and the information professional
“ ... an impressive and comprehensive study. Of special note are the chapters on 'Ontologies and Information Professions'; 'Alternative Semantic Visions'; and 'Ontological Documentation'. Impressively well written, organized, and presented, Practical Ontologies for Information Professionals will prove to be an enduringly valued and appreciated addition to professional, community, and academic library Information Science reference collections and supplemental studies reading lists.”
- Midwest Book Review, Reviewer's Bookwatch
"Practical Ontologies for Information Professionals offers insight into the evolution of classification of digital data and knowledge. This book will be useful to archivists, domain experts, LIS students, and library and information professionals. Recommended."
There are three main aims for this book. The first is to demonstrate to the information professional the importance of ontologies for knowledge discovery. The second is to demonstrate the important contribution information professionals can make to the development of ontologies. Finally, the book aims to provide a practical introduction to the development of ontologies for information professionals. This introductory chapter will, hopefully, already have gone some way to demonstrating the importance of the development of robust and widely used ontologies in the fight against information overload, and the role of the information professional in the process. These ideas will continue to be developed and reinforced throughout the rest of the book.
Chapter 2 – Ontologies and the semantic web
Ontologies have gained added significance in recent years through the adoption of an increasingly semantic web. Chapter 2 provides an introduction to the semantic web and the role of ontologies, and how ontologies have been increasingly adopted in a wide variety of libraries as well as other cultural heritage institutions and commercial organizations.
Chapter 3 – Existing ontologies
There is a wide variety of ontologies that have been developed, and knowledge of the dominant ontologies, their applications and their differences is increasingly essential to the information professional. Chapter 3 considers some of the main ontologies, including those ontologies used for representing ontologies, those widely adopted by libraries and those widely used on the web.
Chapter 4 – Adopting ontologies
The reuse of existing ontologies is important for both the integration of data across different systems and to avoid the repetition of work. Chapter 4 considers the tools that are available for identifying existing ontologies, how the ontologies (or elements thereof) can be combined in the creation of application profiles, and some of the criteria that should be considered when selecting ontologies.
Chapter 5 – Building ontologies
It is increasingly important that information professionals are not only users of existing ontologies, but that they build their own ontology for particular applications. Chapter 5 provides both a methodology for building an ontology and an overview of some of the tools that are available, before leading the reader through the development of a simple ontology with Protégé, the most popular (and free) software for ontology development.
Chapter 6 – Interrogating ontologies
Ontologies are not only of interest for the structure they provide, but also for the data that they contain. Chapter 6 provides an overview of tools available for interrogating semantic web ontologies, both through Simple Protocol and RDF Query Language(SPARQL)and web crawlers, to gain new insights.
Chapter 7 – The future of ontologies and the information professional
The final chapter looks to the future of ontologies and the role of the information professional in their development and use. The future of ontologies will undoubtedly be a mixture of lightweight and more formal ontologies, and their development is likely to be integrated with other technologies such as Natural Language Processing and potentially crowdsourcing workflows. The contribution for the library and information professional to ontology development also has the potential to change, expanding from the bibliographic ontologies that will undoubtedly occupy them in the short term to the development of niche subject specific ontologies in the long term.
