ARNS (Automated Real-time Narrative Summaries)

ARNS is an innovative natural language generation system developed by CoGenTex for NOAA's National Ocean Service (NOS), for use with their Physical Oceanographic Real-Time System (PORTS).

PORTS is a product of NOS's Center for Operational Oceanographic Products and Services (CO-OPS), which collects, analyzes and distributes historical and real-time observations and predictions of water levels, coastal currents and other meteorological and oceanographic data.

Below is a sample of a PORTS screen for San Francisco Bay:

The PORTS system currently displays its real-time data in graphical and tabular form. The tabular form can require lengthy inspection to retrieve the relevant details, particularly in a large PORTS locale with many sensors. ARNS complements the tabular display by providing automatically generated natural-language summaries of port conditions, in order to give users a more comprehensive overview of the data.

ARNS has been deployed publicly since 2008 (see, for example, current conditions for Houston/Galveston Bay).
