EchoMail®: Automatic Document Analysis and Classification (1993-Present)

Following the invention of email by Dr. Shiva in 1978, and up until 1993, email was an inter- and intra- office business application. However, after the advent of the World Wide Web (WWW) in 1992, web-based email applications made email a consumer application resulting in an explosive growth of email usage.

Signal Detection of Email Signals for Automatic Categorization

In 1993, the White House, Executive Office of the President, sponsored an industry-wide competition to automatically to analyze and classify President Clinton’s email to assist in handling the deluge of email. While in the midst of his PhD work, after being selected as the only student participant, Dr. Shiva won this industry-wide competition. This resulted in his being awarded a number of foundational patents in pattern recognition (one of which is shown in Figure 23) and developing EchoMail® – a platform for enabling pattern recognition classification of electronic documents, which led to his starting EchoMail, Inc., a company that grew to nearly $200 million in market valuation. EchoMail was featured in EchoMail enabled the automatic classification and routing of large volumes of email for Global 2000 companies such as Nike, American Express, P&G, Citigroup, to enable rapid response to customer inquiries, as well as to increase levels of customer service.

The approach here, as aforementioned, was to identify the Normal State as well as the Abnormal States of an email, as illustrated below.
