Provides is an information processing apparatus that is capable of efficiently executing a series of tasks related to reading a document. In the information processing system according to the present disclosure a document reading apparatus includes a performance-information-transmitting unit that transmits performance information in accordance with a request from the information processing apparatus. An information processing apparatus includes a performance-information-acquiring unit, a task-sharing unit, and a task-execution-control unit. The performance-information-acquiring unit acquires performance information of the document reading apparatus. The task-sharing unit, in accordance with the performance information that is acquired by the performance-information-acquiring unit, determines which tasks of a series of tasks for data of a document that is read by the document reading apparatus will be executed by an own apparatus and by the document reading apparatus, and shares the tasks. The task-execution-control unit causes tasks that are determined by the task-sharing unit to be tasks that will be executed by the own apparatus to be executed by the own apparatus, and causes tasks that are determined to be tasks that will be executed by the document reading apparatus to be executed by the document reading apparatus, and processes the tasks as a series of tasks.
