Abstract

When accessing an information retrieval system, it has long been said that undergraduates who are in an exploratory stage of researching their essay topic should use a high recall search strategy; what prevents them from doing so is the information overload factor associated with showing the undergraduate a long list of citations. One method of overcoming information overload is summarizing and visualizing the citation list. This paper examines five summarization and visualization schemes for presenting information retrieval (IR) citation output, then discusses whether these schemes are appropriate for undergraduates and other domain novice users. We ask and answer four questions: (1) What is the message these schemes try to communicate and (2) is this message appropriate for domain novice users like undergraduates? (3) How do these schemes communicate their message and (4) is how they communicate the message appropriate for a domain novice? We conclude that (i) the most appropriate message for information space visualizations for domain novice users is associative thinking, and (ii) the message should be communicated with a standardized look that remains relatively constant over time so that the shape and form of the visualization can become familiar and thus useful to students as they navigate their way through the information space produced by a high recall search strategy.
