The parser uses a hidden Markov model (HMM) in which the lines making up an e mail are treated as a sequence of observations of a system that evolves according to a Markov chain having states corresponding to the component parts. The HMM is trained using a manually-annotated set of e-mail messages, then applied to parse other e-mail messages. HMM-based parsing can be further refined or expanded using heuristic post-processing techniques that exploit redundancy of some component parts (e.g., signatures, disclaimers) across a corpus of e-mail messages."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Automated parsing of e-mail messages","description":"An automated parser for e-mail messages identifies component parts such as header, body, signature, and disclaimer.
