Abstract

An exploratory study was conducted of elementary school children searching a full-text electronic encyclopedia on CD-ROM. 28 third and forth graders and 24 sixth graders conducted 2 assigned searches, one open-ended, the other one closed, after 2 demonstration sessions. Keystrokes captured by the computer and observer notes were used to examine user information-seeking strategies from a mental model perspective. Older searchers were more successful in finding required information, and took less time than younger searchers. No differences in total number of moves were found. Analysis of search patterns showed that novices used a heuristic, highly interactive search strategy. Searchers used sentence and phrase queries, indicating unique mental models for this search system. Most searchers accepted system defaults and used the AND connective in formulating queries. Transition matrix analysis showed that younger searchers generally favoured query refining moves and older searchers fovoured examining title and text moves. Suggestions for system designers were made and future research questions were identified

Abstract

Cooper identifies search strategies in 21 seven year old children (entering Piaget's concrete operational stage), and compares these to those characterized by a model of adult search strategies with a particular interest on the impact of visual information. Videotapes were made of behavior at a bookshelf of the children in their regularly scheduled media center class and in visits outside the class time. Children largely ignored the camera and commented on the videotapes in a debriefing session. Field notes were also kept. The analysis produced counts of strategy types using the Belkin model. Thirty-three books on spiders were added to the collection and filed normally in Dewey 595.4. A CD-ROM encyclopedia was also made available and both were utilized. Nine search sessions on the CD-ROM encyclopedia were recorded and a Scan/Learn/Recognize strategy was favored. At the shelf a Scan/Select/Recognize strategy was common with only a few looking beyond the cover to make a selection. Metadata use was discussed and the children agreed it should be used. It was used in the CD-ROM search but not at the shelves. There is a tendency to rely on visual information if available, and it appears the Belkin model can be used to characterize children's search behavior.

Abstract

Information searching in practice seldom is an end in itself. In work, work task (WT) performance forms the context, which information searching should serve. Therefore, information retrieval (IR) systems development/evaluation should take the WT context into account. The present paper analyzes how WT features: task complexity and task types, affect information searching in authentic work: the types of information needs, search processes, and search media. We collected data on 22 information professionals in authentic work situations in three organization types: city administration, universities, and companies. The data comprise 286 WTs and 420 search tasks (STs). The data include transaction logs, video recordings, daily questionnaires, interviews. and observation. The data were analyzed quantitatively. Even if the participants used a range of search media, most STs were simple throughout the data, and up to 42% of WTs did not include searching. WT's effects on STs are not straightforward: different WT types react differently to WT complexity. Due to the simplicity of authentic searching, the WT/ST types in interactive IR experiments should be reconsidered.
