摘要:
Various embodiments for systems and methods of tracking disaster footprints using social streaming media using nonnegative matrix factorization are disclosed herein. The system extracts a summarization output from historical data and compares the summarization output with incoming data to identify differing or similar topics within the data. The summarization output is projected to adjust a time-dependency of the summarization output to enable a more direct comparison. The system additionally uses the summarization output to encode topic data within historical data to reduce computational overhead.
