This paper aims to analyze the behavior and attitude of authors from scientific papers towards keyword selection, investigate the habit of authors in keyword retrieval, and explore the method of keyword optimization. We design a questionnaire about the keyword selection, including keyword retrieval habit, selection method, processing attitude, expectation, etc. Two hundred questionnaires are sent to the authors of Computer Systems and Applications and 152 valid ones are retrieved. In comparison with other modes, authors are inclined to retrieve papers in the subject or keyword mode.71.62% authors pay much attention to keyword selection. 76.97% authors select Keywords only from titles and abstracts. 73.65% authors believe that Keywords are set to reflect the article content and technical points. 79.73% authors have investigated hot Keywords. 89.19% authors think that valid Keywords can increase article display. 93.10% authors hope editorial boards to recommend Keywords. Since authors are lack of effective method, they are powerless in keyword selection. Editors of scientific and technological journals should make in-depth studies in keyword optimization and make efforts together with authors to select more standard and valid Keywords.  相似文献
