Research trends in text mining: Semantic network and main path analysis of selected journals

摘要

In this study, network and main path analyses were conducted on 1856 studies related to text mining, by extracting keywords and citation information from the text of each paper. Our findings indicate that research papers on text mining have been published in 45 academic disciplines in the 1980s and 1990s, 105 disciplines in the 2000s, and 171 disciplines in the 2010s. The results show that using text mining as a research topic and method has rapidly increased. We also demonstrate that the main theme of text mining research is discourse and content analysis in the 1980s and 1990s, biology and data mining in the 2000s, and medicine and advanced text mining in the 2010s. Moreover, we examined the main citation path for text mining studies and suggest that the main focus of text mining studies has evolved from information science to information systems and technology management. Additionally, influential papers have been recently published in fields such as architecture and social ecology revealing the wide scope of text mining. This article presents an understanding of previously unexplored research trends in text mining and how these trends shed light on the most influential academic papers in the field.
