摘要：	SeaSpider is an R&D tool to investigate the development of a software agent that would aid an operator in gathering information about marine vessels from public sources on the internet. This information would supplement sensor information used for Intelligence, Surveillance, and Reconnaissance (ISR) to enhance Maritime Domain Awareness (MDA) and to complete the Recognized Maritime Picture (RMP). Specifically, SeaSpider is fine tuned to search for, organize, and display information about locations (ports), dates and times, and activities (arrival, in berth, departure). One module manages the Google searches and retrieves the html pages; another module extracts relevant ship movement information and populates a database; a third module retrieves information from the database in response to user generated queries. In this memorandum, the SeaSpider concept is introduced, the design details of the prototype are presented, and performance is analysed, with a view to future enhancements. / NOTE: Technical memo. / Supplementary Notes: The original document contains color images. / Availability Note: Order this product from NTIS by: phone at 1-800-553-NTIS (U.S. customers); (703)605-6000 (other countries); fax at (703)605-6900; and email at orders@ntis.gov.
