Indexing and access for digital libraries and the internet: Human, database, and domain factors

Authors


Abstract

Discussion in the research community and among the general public regarding content indexing (especially subject indexing) and access to digital resources, especially on the Internet, has underutilized research on a variety of factors that are important in the design of such access mechanisms. Some of these factors and issues are reviewed and implications drawn for information system design in the era of electronic access. Specifically the following are discussed: Human factors: Subject searching vs. indexing, multiple terms of access, folk classification, basic-level terms, and folk access; Database factors: Bradford's Law, vocabulary scalability, the Resnikoff-Dolby 30:1 Rule; Domain factors: Role of domain in indexing.
