Topic Maps and Entity Authority Records: an Effective Cyber Infrastructure for Digital Humanities

Abstract

The implicit connections and cross-references between and within texts, which occur in all print collections, can be made explicit in a collection of electronic texts. Correctly encoded and exposed they create a framework to support resource discovery and navigation by following links between topics. This framework provides opportunities to visualise dense points of interconnection and, deployed across otherwise separate collections, can reveal unforeseen networks and associations. Thus approached, the creation and online delivery of digital texts moves from a digital library model with its goal as the provision of access, to a digital humanities model directed towards the innovative use of information technologies to derive new knowledge from our cultural inheritance. Using this approach the New Zealand Electronic Text Centre (NZETC) has developed a delivery system for its collection of over 2500 New Zealand and Pacifc Island texts using TEI XML, the ISO Topic Map technology and innovative entity authority management.
