Title: A Formal Description for Visualizing Boolean Queries

Abstract: Data selection by querying, with a visualization-based user interface, is the dominant visual method for seeking information in large knowledge bases. Most commonly users supply queries as Boolean expressions, which are hard for humans to manipulate successfully.

Visual query specification allows users to exploit their visual reasoning skills, better to generate and understand Boolean queries.

Many techniques exist for visual query specification, but there is at present no formalism providing a general mathematical structure within which they can be understood.

This presentation describes a mathematical formalism that contains a general method for designing visual query interfaces. The formalism functions as a source of innovative query designs, some of which are presented here.

5. General Discussion Items

CS 488 t-shirts: They're here; they're going fast (or even if they're not); see Steve to get yours, soon. The cost is $21.
Alias is hiring; Oculus Information is hiring; Side Effects is hiring! If you want a job get one soon. Even better, get two or three.
Time for CS888 this term: 15.30 on Wednesdays.

16.30 today for organizational meeting.
Computer vision and image processing algorithms suggested topic.
