Abstract:
1. A data processing method based on collective document data containing sentences by different writers for generating a candidate synonym for an object word used in the document data, the data processing method comprising the steps of: inputting the object word as a concept for candidate synonyms; generating at least one piece of partial data of the collective document data for a writer, the partial data containing only the sentences by the writer; extracting words contained in the collective document data based on the object word by calculating degrees of relatedness between the extracted words and the object word, and generating a first set of candidate synonyms, which has as elements for the first set, a predetermined number of the extracted words ranked highest in descending order of the degree of relatedness; extracting words contained in the partial data based on the object word by calculating degrees of relatedness between the extracted words in the partial data and the object word, and generating a second set of candidate synonyms for the writer, which has as elements for the second set, a predetermined number of the extracted words ranked highest in descending order of the degree of relatedness; evaluating, among the words contained in the first set of candidate synonyms, the words of the first set, which are matched with the words ranked in places equal to or higher than a threshold value place in any of the second sets of candidate synonyms, are evaluated to be absolute, wherein said absolute, is a definitive candidate synonym; evaluating, among the words contained in the first set of candidate synonyms except the words evaluated to be absolute, the words of the first set, which are matched with the words ranked in places lower than the threshold value place in any of the second sets of candidate synonyms, are evaluated to be negative, wherein said negative is not a definitive candidate synonym; and generating the candidate synonyms for the object word from the words of the first set of candidate synonyms by excluding the words evaluated to be negative, wherein the calculation of the degrees of relatedness is realized by the steps of:
