Abstract: An interactive information map system is disclosed that enables a user to efficiently search through, and determine matches within, large amounts of data including event-location data and person-location data. The interactive information map system may include an interactive user interface in which event-location data, person-location data, and/or matches between event-location data and person-location data may be displayed on a map. Further, a user of the interactive information map system may input search queries to the interactive information map system, including selections of subsets of event-location data and person-location data, for determining matches. The user may limit the search query based on a time or timeframe of interest. Advantageously, according to various embodiments, the interactive information map system may enable a user to identify matches between records of events occurring at particular locations and records of persons being at particular locations.
