We address some issues relating to display of results of passage retrieval from full-text collections. We claim that displaying query results in terms of inter-document similarity is inappropriate with long texts, and suggest instead assigning categories that correspond to documents' main topics. We argue that main topics of long texts should be represented by multiple categories, since in many cases one category cannot adequately classify a text. We describe a new automatic categorization algorithm that does not require pre-labeled texts and a prototype browsing interface that presents a simple mechanism for displaying multi-dimensional information.
