PROBLEM TO BE SOLVED: To extract a technical term from a document related to a specific technical field.SOLUTION: A dictionary term extraction part 30, based on a term dictionary 40, extracts each candidate character string of a term related to a symptom, so that, the candidate character string of the term related to a symptom does not overlap other candidate character string, and a total sum of a corrected dictionary score which is corrected based on a penalty score by an adjustment part 34 becomes maximum. A classification tool term extraction part 32 extracts each candidate character string of the term related to a symptom so that, the candidate character string of the term related to a symptom does not overlap other candidate character string, and a total sum of a corrected classification tool score which is corrected based on penalty score calculated by the adjustment part 34, becomes maximum, based on a classification tool 42. Then the adjustment part compares the candidate character strings of the term related to a symptom, and calculates a penalty score to each candidate character string which does not match. A repetition determination part 36, repeats the above-mentioned steps until the candidate character strings related to a symptom match.SELECTED DRAWING: Figure 2 |
