Timesearcher: Visual Exploration of Time-Series Data
Entry ID: timesearcher
Abstract: Widespread interest in discovering features and trends in time- series has
generated a need for tools that support interactive exploration. The Human
Computer Interaction Lab has built a prototype environment for interactive
querying and exploration of time-series data. Queries are built using
timeboxes: a powerful graphical, direct-manipulation metaphor for the
specification of queries over ... time-series datasets. These timeboxes support
interactive formulation and modification of queries, thus speeding the process
of exploring time-series data sets and guiding data mining. The prototype
includes windows for timebox queries, individual time-series, and
details-on-demand. Other features include drag-and-drop support for
query-by-example and graphical envelopes for displaying the extent of the
entire data set and result set from a given query.
