摘要/Abstract

摘要： 医学类学术论文摘要结构明确,分为目的、方法、结果、结论等4个逻辑项。利用信息熵和手工筛选的方法从摘要各逻辑项中抽取关键词,根据权重对关键词进行排名,并与学术论文中原有的关键词进行对比。为了改进自动抽取的结果,通过java程序计算出摘要中各部分的权重,重新对抽取出的关键词进行排名,以优化自动抽取关键词的效果。根据最优实验结果,摘要的逻辑项中目的、方法、结果、结论的权重为7：1：1：4时,自动抽取到的关键词效果最佳。

关键词: 候选, 自动抽取, 排名

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.
