12 Use of Intelligent Agents at US Pacific Command VIPAR

13 13 USPACOM Command Virtual Information Center Inside China Russia Today Jakarta Post Unorganized Newspaper Articles Analysts Summary CINC Summary Manually gather Information from 20–30 newspapers Manually Organize Information Manually Analyze And Summarize Information Only 10% of available newspapers scanned Entirely manual operation

14 14 New Intelligent Agent Approach Article Retrieval Agents Organize and summarize Articles Inside China Russia Today Jakarta Post CINC Summary Manually Analyze And Summarize Information Automatically Gather, Organize, and Summarize Thousands of articles Analysts Summary Capable of organizing 10,000 article per day Requires only a desktop computer

20 20 Endorsements  US Pacific Command’s CINC Admiral Blair  “A tremendously successful project”  “Software agents … lead to substantially improved analytical products.”  Science and Technology Advisor  “a grand slam home run!”  “first time we've seen information discovery and knowledge management software working at HQ USCINCPAC operationally.”

21 21 Enhanced VIPAR Performance  The Phylips Tree representation of the clustering of 1015 articles  Required almost 360 second (6 minutes) and 241 MB of memory to compute

22 22 Battelle Funded VIPAR Upgrades  Memory  Evaluated caching of document title and collection  Optimized internal data structures  Experimented with clustering partial articles.  Applied Porter’s Stemming Algorithm  Clustering Performance  Clustering algorithm “Clusters in place”  Hybrid clustering approach to large article sets

23 23 Result  The Phylips Tree representation of the clustering of 9461 articles  Required 2.5 minutes (137 seconds) and 495 MB of memory to compute

24 24 Summary  Intelligent agents are a significant future technology direction  We have a significant progression of deployed agent systems and research to our credit  We have ringing endorsements regarding the success of our systems and research  We look forward to the next step…
