System for annotation of electronic messages with contextual information

A system for annotation of electronic messages with contextual information comprising:

• a computer system comprising at least one processor, at least one tangible memory device, and at least one network interface;
• an interface to one or more contextual information sources that communicates over one or more of said at least one network interface;
• a message input module configured to receive an electronic message on one or more of said at least one network interface, said electronic message comprising one or more message artifacts, said message artifacts comprising:
• one or more senders,
• one or more sender addresses,
• one or more sender organizations,
• one or more recipients,
• one or more recipient addresses,
• one or more recipient organizations,

• a location,
• one or more links,
• an importance indicator,
• one or more media types,
• a set of message metadata, and
• one or more attachments;
• a feature extraction module coupled to said message input module and configured to execute on said at least one processor, wherein said feature extraction module
• analyzes said message artifacts of said electronic message, and
• generates a set of features associated with said message artifacts;
• an information selection module coupled to said feature extraction module and to said interface to said one or more contextual information sources, and configured to execute on said at least one processor, wherein said information selection module selects one or more contextual information items from said one or more contextual information sources based on said set of features;
• a message annotation module coupled to said information selection module and to said message input module, and configured to execute on said at least one processor, wherein said message annotation module adds said one or more contextual information items to said electronic message to create an annotated electronic message;
• and,
• a message output module coupled to said message annotation module, wherein said message output module transmits said annotated electronic message on one or more of said at least one network interface to at least said one or more recipients.
