Abstract
An inter-word score calculation apparatus calculates a degree of relatedness between words included in an amount of data from at least one document. The inter-word score calculation apparatus includes a memory storing document data from the documents, term list data wherein predetermined terms are written and a processor. The processor performs a combination process of amplifying an amplification candidate word, which is a word corresponding to a term in the term list data and included in the document data, creating an amplified word, and adding the amplified word to the document data creating processed document data, calculate the degree of relatedness between words included in the processed document data using a predetermined calculation method, and when an amount of documents accumulated in the document data is smaller than a first predetermined amount, add the amplification candidate word to the processed document data.
