“…OCs are defined as geographically dispersed groups in which people interact and share information and knowledge using internet-based technologies (Pai and Tsai, 2016). OC types vary in their purpose (Hagel and Armstrong, 1997) and include online “knowledge sharing communities” (Al-Kurdi et al , 2018), “communities of practice” (Akoumianakis, 2009; Zhao et al , 2018), “blogging communities” (Chu and Kim, 2011), “social media/ networking sites” (Chen and Hung, 2010; Al-Yafi et al , 2018), “health communities” (Fan et al , 2014), “innovation communities” (Debaere et al , 2018), “brand communities” (Zhou et al , 2016), “transactional communities” (Khalifa and Ning Shen, 2008) and “opinion/review communities” (Rathore et al , 2016). Approximately one-third of the world’s population use and participate in some sort of OCs (Balaji et al , 2016), with strong organisational interest in the commercial and social opportunities eWOMs present.…”
