Design of a graphical user interface for focussed retrieval of structured documents

Many document collections contain documents that have signiJicant structure. Structured document retrieval requires diferent models and interfaces from standard information Retrieval. An Information Retrieval system dealing with structured documents has to enable a user to query, browse retrieved documents, and provide query refinement and relevance feedback based not only on full documents but also on specific parts of them, according to their structure. Currently, very few IR systems enable such level of flexibility and interaction, because of limitations in indexing and retrieval models and in interfaces. In this papec we present the design of a new graphical user interface for structured document retrieval. This interface provides the user with an intuitive and yet powerful set of tools for structured document searching, retrieved list navigation, and search refinement.
