11. 11 / 14 Parallel Sets View Parallel Sets – Displays relationships among categorical dimensions – Shows intersections and distributions of categories

12. 12 / 14 Parallel Sets View Dynamic filtering on continuous dimensions can show more information Here we see the large proportion of facility attacks and bombings in Latin America during the early 1980s

13. 13 / 14 Analysis using Longest Common Sequence (LCS) Two strings of data (each representing a series of events) – GATCCAGT – GTACACTGAG Basic algorithm returns length of longest common subsequence: 6 Can return trace of subsequence if desired: – GTCCAG GATCCAGT GTACACTGAG Additional variations can take into account event gap penalties, time gap penalties, and exploration of shorter, or alternate, common subsequences
