Query Similar Event Sequences by Example
Similan is an interactive data analysis tool that helps users find records of event sequences that are similar to the target event sequence. Similan implements a customizable similarity measure which computes how two records are similar or dissimilar. Similan provides a user-interface for the users to select record from the database as a target or create a custom target record, and customize search parameters. After the users perform the search, the similarity scores against the target record for all records are computed and all records are ranked by their similarity scores. The results are visualized on the screen with additional filters that allow users to explore the results.
