In many situations, the search for non-textual information is driven by a specific topic rather than the values of a data record’s attributes. Therefore, data is often indexed with census nomenclatures, classifications or thesauri to allow a user to search with keywords. MURBANDY is a user-friendly graphical interface which supports query formulation using this indexing languages and at the same time visualizes the semantic dependencies between them and other search attributes. The generic version of the user interface is able to display dependencies between keywords and an arbitrary number of databases during query formulation, and lets the user interactively explore and manipulate his query at a very detailed level.
