Abstract:
This article presents a new, hybrid approach that projects an initial query result onto global information, yielding a local conceptual overview. Concepts found this way are candidates for query refinement. We show that the resulting conceptual structure after a typical short query of 2 terms, contains refinements that perform just as well as a most accurate query formulation. Subsequently we illustrate that query by navigation is an effective mechanism which in most cases finds the optimal concept in a small number of steps. When an optimal concept is not found, the navigation process still finds an acceptable sub-optimum.
