1. An information processing apparatus, comprising: a central processing unit (CPU) configured to: obtain a pathological image and a primary diagnosis result from a first terminal via a network, wherein the first terminal is associated with a first user, and the primary diagnosis result is a diagnosis result of the pathological image by the first user; transmit the pathological image and the primary diagnosis result to at least one second terminal via the network, wherein the at least one second terminal is associated with a second user; obtain a first browsing history of the pathological image and an opinion of the second user from the at least one second terminal via the network, wherein the first browsing history at least includes information on observed areas in the pathological image, wherein the observed areas are displayed on a display unit of the at least one second terminal based on an operation by the second user for an observation of the pathological image, and wherein the opinion of the second user is for the primary diagnosis result, and the opinion is based on the observation of the pathological image by the second user; cause reproduction of a motion picture of a browsing behavior stored in a storage unit, wherein the motion picture of the browsing behavior is a video recording of the operation that indicates the browsing behavior of the second user to browse the pathological image; generate a reliability score of the obtained opinion based on the reproduced motion picture of the browsing behavior; obtain scene information of a scene of the pathological image that is associated with a flag, wherein the flag is set by the second user; and adjust the reliability score of the obtained opinion based on an availability of the scene information.
