Abstract: The present invention extends to methods, systems, and computer program products for signal normalization, event detection, and event notification using agency codes. Ingestion modules can ingest different types of raw structured and/or raw unstructured signals on an ongoing basis and possibly including agency codes. The signal ingestion modules normalize raw signals into normalized signals having a Time, Location, Context (or “TLC”) dimensions. An event detection infrastructure determines that characteristics of multiple signals, possibly including agency codes, when considered in combination, indicate an event of interest to one or more parties. Agency codes associated with events can be translated between agency code languages and/or between different agencies/jurisdictions.
