摘要

Co-word analysis plays a pivotal role in the cognitive structure analysis of scientific disciplines.This paper extracts the most frequent 100 words from the dataset of keywords of fourteen key journals in library and information science(LIS) in the Chinese Social Sciences Citation Index(CSSCI) based on the right truncation method.Based on the 100 words,four major branches are identified with hierarchical clustering,then the content characteristics of the fourteen journals are analyzed with hierarchical clustering,multidimensional scaling and heat map.Furthermore,the evolution trajectory and usage trend of the 100 words are studied to reveal the cognitive structure of LIS and its evolutionary process.This paper finds that the LIS in China has different concerns at different times,which has its own life-cycle.Currently,LIS tends to treat 'information' as its research focus,with emphasis on technology application and management innovation.
