ABSTRACT:
A keyword assigning system divides text data into words, stores results of the division in a table, detects numbers of occurrence times of words in each text data, registers them in a table, and obtains word occurrence frequencies in domains on the basis of the table. The system then extract keywords from the text data by domain on the basis of a resulted domain-wise word occurrence collection table, and extracts negligible word not capable of becoming keywords by domain. The system further registers the extracted domain-wise keywords and negligible words in a keyword-negligible word dictionary, looks the keywords and negligible words registered in the dictionary upon assignment of the keywords to the text data to extract words to become keywords from among the words of the text data to have the keywords assigned thereto, and assign the extracted keywords to the text data, thereby automatically making extraction and assignment of most of the keywords.
