| Abstract | My overiil objective is to develop and evaluate ways of automatically incorporating hypert ext links int O pre-existing scholarly journal articles. 1 describe a de-based approach for making three types of links (structural, definition, and semantic). Structural links are a way of making explicit some connections between parts of the text. Definition links connect the use of a term, defined elsewhere in the document, to that definition. Links that connect parts of text that discuss similar things are semantic links. 1 distinguish several types of semantic links. 1 use two information retrieval (IR) systems (Cornellys SMART system and Bellcore's Latent Semantic Indexing) to select links based on the content of the articles. 1 conducted an experiment to compare the performance of the links forged using these two systems. The effectiveness of the links (and the rules used to make them) is tested by people reading the hypertext versions for information under a time constraint. A within-subjects experimental design was used. Each of the nineteen experimental participants read one version of each of three scholarly articles in a dSerent hypertext form (one had only simple links, the others had definition links and semantic links seleded using one of the IR systems). Sub jects' preferences were dso measured Although 1 used three survey articles nom published sources for my evaluation experiment there was no difference in reader preference or performance on the b a i s of article. Subjects ratings of the utility of the various links shows a significant preference for structural links over semantic links. Definition links were preferred to structural Links, although the result was not significant. No Merence between the links created using the two IR systems was detected. However there were significant Merences in the times that readers spent on documents created using the Mnous treatments When they read in documents with only structural links readers were more lïkely to have read the whole article, and their satisfaction scores were inversely proportional to their comprehension score. The method of evaluating hypertext versions of journal articles for use by researchers may be applied to other hypertext versions. |
