What is Co-Occurrence Network

Today, electronic word-of-mouth (eWOM) has a substantial impact on consumers' decisions to purchase tourism and travel services. Therefore, it is essential to have a comprehensive understanding of eWOM in tourism and hospitality research. The chapter aims to conduct a comprehensive examination of the existing body of knowledge pertaining to eWOM communication within the domain of tourism and hospitality. To this end, bibliometric data was obtained from the Web of Science database, utilizing the Bibliometrix R package. The PRISMA flowchart was employed to ensure a systematic examination, which included a total of 515 scholarly documents published between 2008 and 2021. The utilization of a word cloud facilitated the identification of the most prevalent terms within the field, while a thematic map was employed to reveal the themes that guide the existing body of knowledge. Furthermore, co-occurrence analysis was utilized to discern four distinct research themes that have emerged as particularly prominent within the field.
