  3. 3. INTRODUCTION - Event sequences are series of timestamped event - Event sequence analysis 1) the sequence of events e.g. arrival > ICU 2) time gaps between events e.g. ER > (after 5 hours) > ICU - Range from examining a single record in detail to various ways of filtering and searching multiple records - ‘ ’
  4. 4. MOTIVATION ,
  5. 5. MOTIVATION ( bounce back monitoring) Event Definition - ER (Emergency Room) - ICU (Intensive Care Unit) - IMC (Intermediate Care) - Floor - summary of all the transfer sequences and their temporal attributes

  8. 8. RELATED WORK 1) Temporal DataVisualization 2) HierarchyVisualization
  9. 9. RELATED WORK 1) Temporal Data Visualization Single RecordVisualization - long history of visualizing event sequences - most common approach > timeline-based - e.g. row , row Visualization of multiple records in parallel - most common approach > stack instances of single-record - ring / spiral - typically provide searching and filtering mechanisms - e.g. row , row Visualization of combined records - - provide an abstraction of multiple records - (Continuum), (LifeLines2) row , row - ‘ ’
