不同时间段文献检索对查新报告质量的影响

The Influence of Literature Retrieval in Different Time Periods on the Quality of Novelty Search Reports

科技查新报告的有效期一般为一年。为了真正发挥科技查新报告为科技服务的作用,利用世界上两个最大、最有影响力的生物医学数据库PubMed与BIOSIS Previews,分别用同一检索策略检索,比较两个数据库6个月、12个月检出的文献量,以探讨查新报告的合理有效期,为科研工作者和查新员掌握查新的最佳时间提供参考依据。

Sci-tech novelty search report is usually valid for one year. In order to give real play to the function of sci- tech novelty search report in serving the science and technology, this paper selects PubMed and BIOSIS Previews, two largest and most influential biomedical databases in the world, and compares the amount of retrieved literatures in six months and twelve months by suing the two databases and the same search strategy for exploring the reasonable validity period of sci-tech novelty search report and providing references for scientific research workers and novelty search members to master the best search time of novelty retrieval.
