基于主题模型的南水北调东线工程学术关注点研究
Finding academic concerns of South-to-North Water Transfer East Route Project based on topic modeling approach
摘要
Abstract
From 2003 to 2016,a total of 13 valid topics were identified by LDA(latent dirichlet alloca-tion)topic model through the collection of 1405 Chinese documents related to the South-to-North Water Transfer East Route Project.The topics include "engineering construction","pump station operation optimization","water pump performance study","engineering cost research","water environment mo-del","river water pollution","information automation","lake eutrophication","water pollutant","pump structure calculation","pump hydraulic calculation","ecology"and "ecological environment management".Two novel bibliometric indicators,including topic proportion and trend,were construc-ted to describe the academic concerns of the South-to-North Water Transfer East Route Project,finding that"engineering construction"is the most popular topic,followed by"pump station operation optimi-zation"and"water pump performance study".However the"water environment model"and"lake eu-trophication"are becoming a hot topic.The results reflect the attention of the academic circles and provide the basis for the post-evaluation of the South-to-North Water Transfer East Route Project.关键词
