OCLC enlists the cooperation of the world's libraries to make the written record of humankind's cultural heritage more accessible through electronic media. Part of this goal can be accomplished through the application of the principles of knowledge organization. We believe that cultural artifacts are effectively lost unless they are indexed, cataloged and classified.
Accordingly, OCLC has developed products, sponsored research projects, and encouraged the participation in international standards communities whose outcome has been improved library classification schemes, cataloging productivity tools, and new proposals for the creation and maintenance of metadata. Though cataloging and classification requires expert intellectual effort, we recognize that at least some of the work must be automated if we hope to keep pace with cultural change.
Our research explores the following questions:
In a recent article in Scientific American, Tim Berners-Lee argues that the current Web will be transformed into the more intelligent Semantic Web when it is augmented with data for automated processing. For the Semantic Web to work, we must have access to structured collections of information, as well as appropriately annotated Web pages. Since some of the goals of our work are consistent with this vision, we are assessing the utility of the Resource Description Framework (RDF), a building block of the Semantic Web, in making Web documents more accessible by subject.
We draw on our background in information retrieval, Web metadata creation, natural language processing, and our intellectual involvement in two of the world's most widely used library classification schemes to address our reserch questions.
