Abstract
There are numerous problems associated with formulating queries on
networked information systems. These include 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 Rrefinement. This new
approach is based on the concepts of dynamic queries and query previews,
which guides users in rapidly and dynamically eliminating undesired
datasets, reducing the data volume to manageable size, and refining queries
locally before submission over a network. Examples of 2 applications are
given: a Restaurant Finder and prototype with NASA's Earth Observing
Systems--Data Information Systems (EOSDIS). Data architecture is discussed
and user's feedback is presented. Dynamic queries and query previews
provide solutions to many existing problems in querying networked
information systems.
