    •  NEWS   MERL researcher's spam filter finds automobile safety defects at NHTSA
      Date: June 25, 2015
      MERL Contact: William S. Yerazunis
      Research Areas: Data Analytics
      Brief
      • The CRM114 Discriminator, an open-source spam filter / text classifier created by William Yerazunis in MERL's Data Analytics group, continues to turn up in interesting places - and apparently one of them is in the US Department of Transportation's process for analysis of car safety defect reports.

        Although CRM114 is usually used as a spam filter, CRM114 has been used to analyze resumes for jobseekers, scanning outgoing emails to detect accidental confidential information leaks, perusing blogs for relevance, scanning syslog files for interesting events, and now, apparently, searching complaints sent to NHTSA to find safety-related vehicle malfunctions.
