通过运用文献计量和词频统计的方法,比较情报学与传播学、经济学在社交媒体研究程度与焦点上的异同,发现相较于传播学和经济学,基于社交媒体的情报学的研究相对薄弱。通过探索情报学在社交媒体领域中的研究现状,拓展情报学在社交媒体研究中的新方向,并发现基于社交媒体信息传播将成为情报学研究的新焦点。 By using bibliometrics and term-frequency statistics, we compare the similarities and differences between intelligence and communication science and economics in the degree and focus of social media research and find that the research on information science based on social media is relatively weak compared with communication science and economics . By exploring the current status of informatics research in the field of social media, this paper explores the new direction of informatics in social media research and finds that the dissemination of information based on social media will become the new focus of informatics research.
