Abstract: A facility for aggregating information about persons-of-interest for use in an identification system. Person-of-interest information may include, for example, crimes or/and activities for which a person has been suspected, charged, or convicted. Person-of-interest information may include descriptive characteristics of a person, such as a person's name, alias, height, weight, date of birth (“DOB”), or other information that may be used to identify a person. The facility identifies one or more data sources from which to retrieve person-of-interest information. For each person of interest, the facility parses from the retrieved information a plurality of attributes characterizing the person of interest, and stores the parsed information in a record associated with the person of interest. Based on the attributes characterizing the person of interest, the facility may determine a relative level of danger posed by the person.
