Building a Digital Library for Computer Science Research: Technical Issues
Ian H. Witten, Craig G. Nevill-Manning, Sally Jo Cunningham · 1996
Technical reports are available electronically at hundreds of internet sites around the world. A major impediment to their utility in computer science research is the difficulty in locating reports that are relevant to a particular area. We describe the implementation of a digital library for computer science technical reports that indexes every word in each report, covers a majority of computer science technical report archives, and supports a variety of search types despite the fact that documents are not formally cataloged. We discuss in detail techniques for constructing the digital library that minimize Internet and local storage costs. Keywords Digital libraries, information retrieval, data compression, user interfaces 1 Introduction The New Zealand Digital Library for Computer Science Research is a pilot project designed to explore the potential of network-based digital libraries. 1 Currently, it provides access to 11,200 research documents worldwide (310,000 pages, 130 mil...
