Creating Visualisations for Digital Document Indexing

Abstract

Indexes are a well established method of locating information in printed literature just as find is a popular technique when searching in digital documents. However, document reader software has seldom adopted the concept of an index in a systematic manner. This paper describes an implemented system that not only facilitates user created digital indexes but also uses colour and size as key factors in their visual presentation. We report a pilot study that was conducted to test the validity of each visualisation and analyses the results of both the quantitative analysis and subjective user reviews.
