With ever-increasing amounts of data in repositories, finding the information a user needs becomes increasingly challenging. When users approach an information access system they often do not have a clear understanding of how to access the precise information they need. Additionally, it is not rare that users have only a vague notion of what they are looking for, hence the need for an exploratory navigation tool beyond a static list of search results. A model used in practice is an iterative search-and-browse cycle to retrieve relevant information. The role of the user interface in understanding search results and providing relevant metadata in a compact manner is a key component of this iterative process. In this context we present WISDNA as an information visualization paradigm for XML data from web information services.
