Pragmatic links express a relation between a text and its possible use. Subjects in a browsing task were tested on content assimilation, and surveyed as to attitude toward the system. In the querying task subjects were asked a series of data specific questions using the system while accuracy, time and number of screens viewed were recorded. Labeling reduced the use of semantic links but had little effect on the use of rhetoric or pragmatic links. No significant learning change was indicated by the use of labels in the browsing task.
Labels lead to significantly higher scores in the querying task.
Attitudes did not vary in the browsing task, and overall impressions did not vary in the querying task. However, participants without labels found it more difficult to move between topics, and those with labels felt more comfortable moving sequentially through the file than did those without, even though they did not use this technique more than others. Experiments with a Stemming Algorithm for Malay Words Fatimah Ahmad, Mohammed Yusoff, and Tengku M. T. Sembok Past work on stemming algorithms has concentrated on the removal of suffixes. Ahmad, Yusoff, and Sembok point out that in languages like Malay or Arabic variant formation depends on prefixes as well as suffixes. Othman's algorithm uses 121 morphological rules and a large Malay dictionary which is a necessary supplement to avoid high error rates in stemming Malay words.
