Abstract

Abstract: The abstract of Medical academic article has a clear structure including objective, methods, results, conclusions. This paper used information entropy and manual screening method to extract keywords from each logic item of abstract, and then ranked the keywords and compared with original keywords. To improve the results of automatic extracting method, it calculated the weight of each item in abstract by using java program and offered a new ranking for the extracted keywords. The optimal experimental results showed that the ratio 7:1:1:4 for logic item could get the best effect of automatic extraction.
