It is found that since the concept of " sponge city" was firstly proposed in 2012,development research of sponge city involves 40 subject fields and is mainly published in 32 kinds of journals,which is dominated by natural science research( 1427 literatures). Researchers are mainly from each college and university,some design institutes and Chinese Academy of Sciences. The research could play certain guidance significance for further research and construction of ecological city construction in China.展开更多
由于传统方法在图书馆文献信息智能检索中应用效果不佳,不仅平均正确率(Mean Average Precision,MAP)较低,而且衡量搜索引擎算法的指标(Discounted Cumulative Gain,DCG)具有较低的归一化止损值,为此提出应用数据挖掘的图书馆文献信息...由于传统方法在图书馆文献信息智能检索中应用效果不佳,不仅平均正确率(Mean Average Precision,MAP)较低,而且衡量搜索引擎算法的指标(Discounted Cumulative Gain,DCG)具有较低的归一化止损值,为此提出应用数据挖掘的图书馆文献信息智能检索方法。首先,利用数据挖掘技术估测出嵌入的检索词条与检索文本的相关性;其次,考虑用户反馈构建逻辑回归判断模型;最后,根据逻辑回归判断模型结合最佳权重实现信息检索。实验证明,设计方法MAP值为0.95~0.98,DCG归一化止损值在0.86以上,证明应用设计方法可更好地进行图书馆文献信息检索,应用效果更好。展开更多
