Automatic modification of message signatures using contextual data

A method for automatic modification of a signature for an electronic message using contextual data, implemented by a processor, comprising:

• receiving, by a contextual analyzer from a conversation client, message text for the electronic message from a sender to a recipient;
• extracting, by the contextual analyzer, message content from the message text;
• using at least the message content, determining, by a relationship analyzer, a relationship context for the sender and the recipient, the relationship context capturing a nature of the relationship between the sender and the recipient;
• using at least the message content, determining, by a temporal context analyzer, a temporal context for the message content, the temporal context capturing temporal features of the message content;
• using at least the message content and a history of electronic conversations between the user and the recipient, determining, by a historical context analyzer, a historical context for the sender and the recipient, the historical context capturing a nature of electronic interactions between the sender and the recipient over time;
• using at least the message content, determining, by a tone analyzer, a tone category for the message content, the tone category capturing a primary tone and strength of the primary tone of the message content;
• selecting, by a signature producer, a signature template of a plurality of signature templates in a template repository mapped to a combination of contextual data matching the relationship context, the temporal context, the historical context, and the tone category, the signature template comprising a set of sections;
• for each section of the set of sections, searching, by the signature producer, a mapping database for an entry matching the combination of the contextual data, the entry comprising a section value associated with the combination of the contextual data;
• for each section of the set of sections, extracting, by the signature producer, a corresponding section value from the entry;
• modifying, by the signature producer, a signature for the electronic message by inserting the section value corresponding to each section of the set of sections in the signature template;
• and
• inserting, by the signature producer, the modified signature into the message text.

A computer program product for automatic modification of a signature for an electronic message using contextual data, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:

• receive message text for an electronic message from a sender to a recipient;
• extract message content from the message text;
• using at least the message content, determine a relationship context for the sender and the recipient, the relationship context capturing a nature of the relationship between the sender and the recipient;
• using at least the message content, determine a temporal context for the message content, the temporal context capturing temporal features of the message content;
• using at least the message content and a history of electronic conversations between the user and the recipient, determine a historical context for the sender and the recipient, the historical context capturing a nature of electronic interactions between the sender and the recipient over time;
• using at least the message content, determine a tone category for the message content, the tone category capturing a primary tone and strength of the primary tone of the message content;
• select a signature template of a plurality of signature templates in a template repository mapped to a combination of contextual data matching the relationship context, the temporal context, the historical context, and the tone category, the signature template comprising a set of sections;
• for each section of the set of sections, search a mapping database for an entry matching the combination of the contextual data, the entry comprising a section value associated with the combination of the contextual data;
• for each section of the set of sections, extract a corresponding section value from the entry;
• modify a signature for the electronic message by inserting the section value corresponding to each section of the set of sections in the signature template;
• and
• insert the modified signature into the message text.
