  • 1.Ontology and Ontology Libraries: a Critical Study

2. Outline Introduction and Overview Languages for expressing Ontologies Tools for building Ontologies Ontology Libraries Evaluation criteria Transitions to the future 3. What is Ontology? The term "ontology" can be defined as an explicit specification of conceptualization. 1. Ontology is a term in philosophy and its meaning is ``theory of existence''. 2. Ontology is a body of knowledge describing some domain. 4. Ontology-Definition Ontologies to capture human knowledge based on common sense. - Lenat y Guha (1990)Source: http://www.emiliosanfilippo.it/wp-content/uploads/2011/11/Ontology-3.jpg 5. How are Ontologies currently being used to Librarians? Standardize vocabulary. Provide better routes. Provide better search.Source: http://gonereading.com/newshop/wpcontent/uploads/2012/01/Librarian-Gift-446x446.png 6. Languages for Expressing Ontologies 7. Tools for Building ontology The are many Ontology tools are available in the present times such as Protg, OntoEdit, Ontolingua, OilEd, pOWL etc.Source: http://www.colourbox.com/preview/2456889-245207-three-3d-people-with-the-tools-in-the-hands-of.jpg 8. Protg Free, open source Web client and format Strong communitySource: http://www.racer-systems.com/img//logo/protege.gif 9. Ontology built using ProtgSource: http://protege-ontology-editor-knowledge-acquisition-system.136.n4.nabble.com/attachment/4658809/2/jbddhbbc.png 10. What is Ontology Libraries (OL)? Ontology libraries are the systems that collect ontologies from different sources and facilitate the tasks of finding, exploring, and using these ontologies.Source: http://semanticweb.com/files/2013/09/9685321345_afc5296f95.jpg 11. Need for ontology libraries Enables and facilitates interoperability Well-established and well-tested ontologies Integrates the data much more easily (Contd.) 12. Need for ontology libraries Find and determine the domain Ontology in specific format Publish their ontology 13. Characteristics of ontology libraries 14. Purpose and Coverage What is it for? -Domain -Intended scope 15. Library content What is in it? -Ontology and how they are collected -Gatekeeping -Mappings and other inter-ontology relations -Metadata 16. Main function for users What does it let you do? -Finding, Search and evaluating ontologies -Browsing -Programmatic access 17. Other features What else is there? -Versioning -Reasoning -User management -Notifications 18. What OL offers!! Ontology library systems oer functions for managing, adapting and standardizing groups of ontologies, for indexing content with ontologies, and for utilizing ontologies in applications.Source: http://assets.fiercemarkets.com/public/newsletter/fiercehealthit/telehealth4.jpg 19.
