Abstract

Elementary-age children (ages 6-11) are among the largest user groups of computers and the Internet. Therefore, it is important to design searching and browsing tools that support them. However, many interfaces for children do not consider their skills and preferences. Children are capable of creating Boolean queries using category browsers, but have difficulty with the hierarchies used in many category-browsing interfaces because different branches of the hierarchy must be navigated sequentially and top-level categories are often too abstract for them to understand. Based on previous research, the authors believe using a flat category structure, where only leaf-level categories are available and can be viewed simultaneously, might better support children. However, this design introduces many more items on the screen and the need for paging or scrolling, all potential usability problems. To evaluate these tradeoffs, the authors conducted two studies with children searching and browsing using two types of category browsers in the International Children's Digital Library. Their results suggest that a flat, simultaneous interface provides advantages over a hierarchical, sequential interface for children in both Boolean searching and casual browsing. These results add to our understanding of children's searching and browsing skills and preferences, and possibly serve as guidelines for other children's interface designers.

Abstract

Information retrieval and exploration of work domains through databases and integrated information systems has become increasingly important in many modern work settings (as well as in libraries). The problem space of the users is defined on occasion by the dynamically changing requirements from their tasks and goals. it is argued that IR system design should be based on an analysis of the properties of the work domain, the task situation and the user characteristics. The paper describes a general framework for IR system design that has been used in the design of a library system. A special problem identified from use of the framework in domain analysis of fiction retrieval is treated in more detail: mapping the authors' domain structures to the domain structures expressed in users' needs in indexing and representation of fiction
