With reference to information storing a co-occurrence probability of each of plural words in association with each of distribution-destinations, the apparatus extracts, from a message to be distributed, an unknown-word that is not included in the plural words, where the co-occurrence probability indicates a probability that each word is included in a message to be distributed to each distribution-destination. When the unknown-word is present in the message at a predetermined ratio or greater, the apparatus extracts first-words included in all of a first-group of messages each including the unknown-word, calculates the co-occurrence probability of the unknown-word for each distribution-destination, based on the information regarding the distribution-destinations to which a message including the first-words and a second-word, which is included in all of a second-group of messages each including the first-words and not including the unknown-word, is to be distributed, and registers the calculated co-occurrence probability in the information.
