| Abstract | Formulating queries on networked information systems is laden with problems: data diversity, data complexity, network growth, varied user base, and slow network access. This paper proposes a new approach to a network query user interface which consists of two phases: query preview and query refinement. This new approach is based on dynamic queries and tight coupling, guiding users to rapidly and dynamically eliminate undesired items, reduce the data volume to a manageable size, and refine queries locally before submission over a network. A two-phase dynamic query system for NASA's Earth Observing Systems--Data Information Systems (EOSDIS) is presented. The prototype was well received by the team of scientists who evaluated the interface. Keywords: User interface, direct manipulation, dynamic query, metadata, query preview, query refinement, EOSDIS. INTRODUCTION The exploration of networked information resources becomes increasingly difficult as the volume of data grows and as the co... |
