Visual Query of Multi-Dimensional Temporal Data
Jerry Alan Fails, Amy Karlson & Layla Shahamat

Abstract:
In this work we present an integrated interface for visual query and result-set visualization for search and discovery of temporal patterns within multi-dimensional data sets. Many have proposed visual query languages for temporal data but fail to address the presentation of the results. Others have designed successful visualizations of temporal data, but do not include support for ad-hoc query of interesting patterns. We couple both stages of temporal query in a single tool for exploration and discovery of temporal patterns. We define temporal patterns as sequences of Events with inter-event TimeSpans. Pattern queries allow for Event and TimeSpan attributes to be constrained in different ways. We formalize the types of pattern queries our system supports according to the levels of restriction imposed upon both Events and TimeSpans.
