A network text analysis of published papers in service business, 2007-2017: research trends in the service sector

The service sector has become the most important part of the global economy. Thus, Service Business: An International Journal (SB) was launched in 2007 to deliver innovative studies that can provide resonating insights to researchers and practitioners in services. This study analyzed 311 articles published in SB during the past 10+ years (2007-2017) by conducting network text analysis (NTA). The published papers' keywords link relations were analyzed to create network maps of research topics, ranging from traditional to emerging ideas of researchers. Influential research topics and their clusters were identified using centrality and community analyses. Research trends were identified for the first 5 years (Volume 1-5) and later years (Volume 6-11) separately through NTA. The results reveal interesting change in research topics over time. Common keywords of studies published in the first 5 years were: Service, Innovation, Customer, Strategy, Tourism, and Quality. The primary frequent keywords of articles published during 2012-2017 were: Customer, Quality, Satisfaction, Innovation, Mobile, and Technology. The results of the study shed valuable insights to the researchers and practitioners in the service sector. Applications of keyword network building and analysis methods provided in this study would be helpful to researchers who are interested in exploring trends of emerging new topics.
