6. A computer system comprising: at least one processor circuit that includes: a monitoring engine configured to: receive a message that specifies a recipient and a sender and that includes a text body; identify, from within a text body, a first text portion associated with an abbreviation; and a processing engine configured to: retrieve a profile of the sender and a profile of the recipient, wherein the profile of the sender contains online content exposure information that is generated from a history of the sender's online activities, and the profile of the recipient contains online content exposure information that is generated from a history of the recipients online activities; identify, based on the profile of the sender, one or more solutions for the first text portion associated with the abbreviation; score each of the one or more solutions using the profiles of the sender and recipient, wherein the scoring includes a first score which reflects the likelihood that the each of the one or more solutions is the abbreviation the sender intended based upon online content exposure information in the profile of the sender, and a second score which reflects the recipient's familiarity with and knowledge of the each of the one or more solutions based upon online content exposure information in the profile of the recipient; identify, based on the scoring, a particular solution of the one or more solutions for use, wherein the identifying based on the scoring by combining the first score and the second score to calculate an overall confidence value that reflects the accuracy of the particular solution; modify the text body of the message to include the particular solution, wherein modifying the text body comprises expanding a first instance of the abbreviation and leaving other instances of the abbreviation collapsed, based on the profile of the recipient; and transmit the message and the confidence value, as modified, to the recipient.
