摘　　要：在文献管理和研究中经常会做关键词提取的工作,通过人工的方式进行提取过程繁杂,工程量极大,因此引入一种关键词欲提取的方式,其过程主要采用以下三个步骤:先通过OCR系统对图片进行识别、排错;再通过词频技术,来提取词频及关联性最高的关键词,将其作为备选关键词;然后通过人为阅读的方式,按照一定的关键词人工提取规则进行关键词的精确提取。结果表明,该方法取得了较好的效果。The keyword extraction work is often done in the literature management. The artificial extraction may cause a complex process, and the work burden is heavy. A method of keyword pre-extraetion is introduced, which is mainly divided into three steps： the image recognition and troubleshooting are conducted first by OCR system; the word frequency technology is used to extract the word frequency and highest relevance keywords as alternative keywords; and then through man-made reading manner, the accurate extraction of keywords is achieved in accordance with a certain keyword manual extraction rule.
