Abstract: The present invention extends to methods, systems, and computer program products for filtering signals during major events. A major event is detected in a geographic area based on one or more of: signal volume, signal diversity, severity, content, or historical events associated with ingested digital signals corresponding to the geographic area. An event-specific filter is deployed. The region associated with the major event is locked to the geographic area. Filtering out a commentary signal purportedly related to the major event is filtered out in accordance with rejection criteria. Filtering out the commentary signal can include determining the commentary signal originated outside the geographic area. It is determined that the major event has ended. The event-specific filter is disabled.

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.
