Use of technology to organize content into groups so it can be retrieved when needed. The result of automatic classification is either a content collection clustered into groups (possibly a candidate taxonomy), or content categorized according to a pre-existing taxonomy. The best results are obtained by defining a business process that combines manual and automated processing so that technology is leveraged and human editorial input is optimized.
A set of 15 metadata elements (the Dublin Core Metadata Element Set) used to describe and catalog content so it can be discovered and retrieved. The Dublin Core is the de facto standard for cataloging web content.
Dublin Core metadata example:
Overall scheme for organizing content to solve a business problem such as improving search, browsing for content on an enterprise-wide portal, enabling business users to syndicate content, and otherwise providing the basis for content re-use. The basic idea behind taxonomy is to provide a controlled vocabulary for metadata attributes, and to specify relationships between terms in the controlled vocabulary. The simplest relationships are broader, narrower, and related, but relationships can be much more specific and complex. Click here for a glossary of taxonomy terms.
