OCLC's Web Characterization Project involves describing the structure, size, usage, and content of the Web. A survey form is available online that will help focus the research. The current research involves taking a representative sample of Web sites which will be used to make reliable inferences about the Web as a whole.
The Digital Knowledge Center (DKC) at the Milton S. Eisenhower Library of The Johns Hopkins University is developing a workflow management system aimed at reducing the amount of human labor and time needed for large-scale digitization projects such as the one currently underway with the Lester S. Levy Collection of Sheet Music. This paper covers the second phase of that project (Levy II). The goals of the second phase are to: reduce costs for incorporating large digitization projects into the collection by creating processes, tools, and interfaces for workflow management; increase access capabilities to the digitized collection via research tools; and to demonstrate the utility of the workflow mangement system. In order to incorporate the newly digitized material into the existing collection in a cost efficient manner, automated tools were developed to reduce the amount of human labor involved in creating the metadata and increased access to the new material. An automated name authority control system (ANAC) was developed to enhance access to the Levy Collection by introducing authorized name searching. The ANAC would also reduce labor costs and improve interoperability of Levy metadata with other collections by using standard data sources and format. This system would also produce a name match confidence value so that managers can establish thresholds that trigger manual intervention. The search engine that is being developed augments metadata searching with unique search capabilities for lyrics and music. Secondary and parallel indices provide a versatile means of searching a variety of documents. The use of partitions on metadata fields allows for metadata-based searching and retrieval and a way to segment documents. Although the workflow management system was developed specifically for the Levy sheet music collection, the authors feel that the tools are generalized enough so that other collections can benefit from them.
