PROBLEM TO BE SOLVED: To perform ranking of a word having a plurality of meanings as to what meaning it is likely to be used according to a retrieval object.SOLUTION: A word meaning characterizing word extraction unit 11 of a word meaning analysis device 1 extracts a word meaning characterizing word which characterizes each word meaning out of word meaning description text data in which a plurality of word meanings are described about a word having a plurality of meanings. A related word extraction unit 12 extracts a related word of the word out of a collection of text data on the basis of a co-occurrence relation with the word having a plurality of meanings. A similarity calculation unit 13 calculates similarity between the word meaning characterizing word which is extracted by the word meaning characterizing word extraction unit 11 and the related word extracted by the related word extraction unit 12. A ranking processing unit 14 determines the order of likelihood to be used of the word meaning corresponding to each word meaning characterizing word on the basis of the similarity calculated by the similarity calculation unit 13.
