1. A non-transitory processor readable medium for storing a database, the database being configured to be readable by at least one processor for instructing the at least one processor to execute a computer process, wherein the database comprises: common linguistic model data configured to be accessible by the at least one processor to stochastically infer a word or a sentence from a character acquired by recognizing a language input by a user; and individual linguistic model data configured to be accessible by the at least one processor to stochastically infer an individual use word or an individual use sentence related to the user by collecting recognition-related information transmitted through one or more client devices used by the user after storing the common linguistic model data, and wherein the at least one processor is configured to: analyze the collected recognition-related information, which is used by the user of a linguistic recognition device, to acquire the individual linguistic model data, extract the individual use word excluded from the common linguistic model data, and store the extracted individual use word as the individual linguistic model data.
