This paper describes a means of extracting the highly credible opinion ratings from Web pages. The principle behind our proposal is based on extracting the co-occurrence relation between a word representing a feature in the specification of a product or service produced by a company and a word showing a consumer's evaluation and then enlarging the dictionaries by registering additional words or phrases that appear in the co-occurrence relation.
