摘要
[目的/意义]针对需采集评价体系指标数据进行二次处理的传统纸质资源评价方法,提出一种基于免疫原理的差异性需求实时提取模型。[方法/过程]对借阅记录分类号编码,进行连续位匹配阴性选择,系统将生存期内达到活化阈值的需求提交确认,得到纸质资源采购需求库。[结果/结论]经验证,该方法能及时发现用户新需求,模型应用较传统方法实时有效。
[Purpose/significance]The paper proposes a real-time extraction model of differential demand based on immune principle aiming at the traditional paper resources evaluation method which needs evaluation system indicators data to be collected for secondary processing.[Method/process]The paper codes the classification numbers of borrowed records and carries out the continuous bit matching negative selection,then,the system will submit and confirm the requirement achieving the activation threshold during the lifetime,and obtain the paper resources purchasing requirement database.[Result/conclusion]It is proved that this method can discover the new needs of users in time,and application of the model is more effective and real-time than traditional method.
