- Abstract
- Proposes a method of organizing documents based on the concepts of aggregation and hierarchies and a graphical user interface to provide a more intuitive form of Boolean query. The design is based on mapping the nodes of the aggregation hierarchy to Boolean intersection operations, mapping the nodes of the generalization hierarchy Boolean intersection operations (?), and providing a concrete, graphical, manipulable representation of both these node types. A working prototype interface was constructed and evaluated experimentally using 16 subjects against a classical command-line Boolean query interface. The graphical interface produced less than one-tenth of the errors of the textual interface, on average. Significant differences in time spent specifying queries were not found. Makes observations and comments to provide guidance for designers
