Abstract: It has been well documented that Web searchers have difficulties
crafting queries to fulfill their information needs. The VisiQ system uses a
concept knowledge base produced using the ACM Computing Classification System
to generate a query space that represents the query terms in relation to the
concepts they describe and the terms that are related to these concepts. A
visual representation of this query space allows the users to interpret the
relationships between their query terms and the query space. Interactive query
refinement within this visual representation takes advantage of users' visual
information processing abilities, allowing them to choose terms that accurately
represent their information needs. A preview of the search results from Google
provides the users with an indication of the current state of their query
refinement process. VisiQ allows the users to take an active role in the
information retrieval process, supporting the fundamental shift from
information retrieval systems to information retrieval support systems.
