3. The computer program product of claim 1 , wherein the output device is a display device, the received message is a message to be displayed on the display device, and the translated message is a translated message displayed on the display device.
1. A computer program product comprising a non-transitory computer readable storage medium having a computer readable program stored therein, wherein the computer readable program, when executed on a computing device, causes the computing device to: automatically track language based user activities occurring via the computing device to at least one other computing device via a communication connection; automatically analyze the language based user activities to determine a relative priority ordering of one or more languages used by a user performing the user activities; automatically generate a sequence of preferred language translation substitutions for outputting messages based on results of the analysis, wherein the sequence comprises two or more preferred language translation substitutions for outputting the messages; automatically apply the sequence to a received message from a process associated with the computing device to generate a translated message using one of the preferred language translation substitutions in the sequence of preferred language translation substitutions, wherein the sequence is automatically applied to the received message from the process by overriding a user defined sequence of preferred translation substitutions and giving priority to the automatically sequence and wherein the computer readable program to automatically apply the sequence to the received message further causes the computing device to: traverse, in a sequence order, the preferred language translation substitutions of the sequence; for each preferred language translation substitution in the sequence order: determine whether a source of the received message has a translation catalog file corresponding to the first preferred language translation substitution in the sequence order, wherein each translation catalog file comprises a translation in an associated language; responsive to a failure of the source of the received message having the translation catalog file corresponding to the first preferred language translation substitution in the sequence order, determine whether the source of the received message has a translation catalog file corresponding to the next preferred language translation substitution in the sequence order; and responsive to the source of the received message having the translation catalog file corresponding to the next preferred language translation substitution in the sequence order, select the next preferred language translation substitution as a preferred language translation substitution to use in generating the translated message; and generate the translated message using the selected preferred language translation substitution to translate the received message into a different language from a language in which the received message is received; and output the translated message via an output device of the computing device.
