<P>PROBLEM TO BE SOLVED: To automatically determine whether a reported side effect of a medicine subject to determination is known. <P>SOLUTION: A similar medicine recognition part 105 recognizes a similar medicine to a medicine subject to determination, and a side effect keyword extraction part 107 extracts a side effect phrase subject to determination from a safety information report document 205. A side effect determination/learning part 108 instructs a keyword similarity evaluation part 109 to evaluate the combination of the side effect phrase subject to determination with a phrase indicating a side effect in an attached document 202 to the similar medicine, and compares the evaluation with a threshold to determine whether a side effect indicated by the side effect phrase subject to determination is known to the similar medicine. The keyword similarity evaluation part 109 tabulates evaluations of similarity between character substrings divided from the two phrases to evaluate a similarity between the two phrases. A character substring similarity evaluation part 110 gives an evaluation higher than the sum of an evaluation for matching character substrings of a first length and an evaluation for matching character substrings of a second length when character substrings of a third length equal to the first and second lengths match. <P>COPYRIGHT: (C)2011,JPO&INPIT |
