29. The system of claim 23 , wherein the operations comprise: after selecting the dominant natural language, reconfiguring the optical character recognition engine from the second configuration to a third configuration that is different from the first configuration and the second configuration, wherein the third configuration of the optical character recognition engine is based at least in part on the selected dominant natural language; and performing a third optical character recognition process with the reconfigured optical character recognition engine on one or more pages of the document to generate a third output response, wherein the third optical character recognition process uses the third configuration of the optical character recognition engine.
30. The system of claim 29 , wherein the operations comprise: determining that the generated third output response is not consistent with the selected dominant natural language based at least in part on recognized words of the generated third output response; and in response to determining that the generated third output response is not consistent with the selected dominant natural language, reconfiguring the optical character recognition engine to a fourth configuration that is different from the first configuration, the second configuration, and the third configuration, wherein the fourth configuration of the optical character recognition engine is based at least in part on a natural language that is different from the selected dominant natural language.
