Abstract
A similarity evaluation program capable of determining similarity between probability models at a high speed (with little calculation) is disclosed. The similarity evaluation program is implemented on an apparatus such as a computer for evaluating similarity between a pair of probability model information each including a plurality of probability information constituted by a plurality of types of data, and this apparatus is provided with a dynamic programming operation unit for performing arithmetic processing based on dynamic programming techniques using a similarity value indicating similarity between probability information included in one of the pair probability model information and probability information included in the other of the pair of probability model information as an indicator for selecting a path.
