TY - RPRT T1 - Visual Specification of Queries for Finding Patterns in Time-Series Data (2001) Y1 - 2005 A1 - Hochheiser,Harry A1 - Shneiderman, Ben KW - Technical Report AB - Widespread interest in discovering features and trends in time- series has generated a need for tools that support interactive exploration.This paper introduces timeboxes: a powerful graphical, directmanipulation metaphor for the specification of queries over time-series datasets. Our TimeFinder implementation of timeboxes supports interactive formulation and modification of queries, thus speeding the process of exploring time-series data sets and guiding data mining. TimeFinder 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. Extensions involving increased expressive power and general temporal data sets are discussed. JA - Institute for Systems Research Technical Reports UR - http://drum.lib.umd.edu/handle/1903/6479 ER -
