Ontologies are increasingly used in various fields such as knowledge management, information extraction, and the semantic web. However, it is useful to know the quality of a particular ontology before deployment, especially in the case when there are numbers of similar ones. Ontology evaluation is the problem of assessing a given ontology from the point of view of a particular criterion of application, typically in order to determine which of several ontologies would better suit a particular purpose. An ontology contains both taxonomic and factual information. Taxonomic information includes information about concepts and their association usually organized into a hierarchical structure. This paper addresses the evaluation of such taxonomies.

The Library of Congress, U.S. and Publisher Liaison Division is pleased to announce that as of September 2010 the Annotated Card Program is officially renamed the Children's and Young Adults' Cataloging Program. The Library of Congress initiated the Annotated Card Program in the fall of 1965 and it is one of its oldest programs. Though renamed, the program will continue to provide the same services. The new name, which now contains the word "cataloging," better defines the activity of the program. The inclusion of "children" and "young adult" in the name specifically identifies the audience for the types of materials handled by the program.
The Children's Literature Section, under the U.S. and Publisher Liaison Division, is responsible for the Children's and Young Adults' Cataloging Program. It catalogs the wide range of fiction material published for children and young adults. The records created, which include an objective and succinct summary of the book, are primarily used by publishers, school libraries, and public libraries. The section also develops new children's subject headings, proposes changes to existing headings, monitors the policies and practices of children's cataloging, keeps abreast of trends in children's publishing, and responds to queries related to the cataloging of children's and young adults' material. The Children's Literature Section actively participates in the American Library Association Committee on Cataloging of Children's Materials and solicits its advice and feedback when developing policy for children's cataloging. The section will continue the services of the program under its new name, Children's and Young Adults' Cataloging Program.
