Abstract

The present invention extends to methods, systems, and computer program products for deriving signal location from signal content. In general, signal ingestion modules ingest different types of raw structured and/or raw unstructured signals on an ongoing basis. The signal ingestion modules normalize raw signals to form normalized signals. In one aspect, a raw signal is ingested. A derived signal is derived from the raw signal. A list of one or more geo cells where the raw signal potentially originated is accessed. A location annotation identifying a geo cell from among the one or more geo cells is formulated. The derived signal is annotated with the location annotation. A location in a two dimensional space is determined from the location annotation. The location is inserted into the derived signal forming a normalized signal.
