ABSTRACT:
The invention provides an information recognition apparatus for recognition of an address or the like which can recognize recognition object information, which is inputted in the form which does not have punctuations or element designations, at a high speed and with a high degree of accuracy. An element word recognition unit detects element word candidates of each information element of recognition element information and likelihoods of the element word candidates. A record number acquisition unit retrieves a record storage unit to acquire, for each element word candidate detected by the element word recognition unit, a record number of a record including the element word candidate. A likelihood calculation unit calculates likelihoods of the records using corresponding likelihood counters. A result discrimination unit discriminates a record to be determined as a recognition result of the recognition object information based on count values of the likelihood counters, and a result extraction unit extracts a record to be determined as a recognition result from the record storage section based on a result of the discrimination of the result discrimination unit.
