The papers were analysed in terms of publication by knowledge area, number of studies published every year, contribution by countries, number of authors and most influential journals. VOS viewer was used to perform a visual analysis on co-occurrence of keywords and document citations.FindingsAccording to the findings, the Scopus database includes 151 (34.40%) documents on business, management and accounting, and 89 (20.27%) documents on social science. It was reported that 29 documents were published in 2018, followed by 54 documents in 2019 and 56 documents in 2021. Malaysia has contributed 86 documents on Islamic tourism, whereas Indonesia has contributed 64 documents. The paper also discusses other interesting findings.Research limitations/implicationsThe bibliometric analysis carried out was confined to Scopus data. Other national and international databases were not taken into account for this research.Originality/valueBetween 2004 and 2021, this study examined relevant studies on Halal and Islamic tourism. The study presents a concise review of the literature accessible to researchers working in this area and provides recommendations for future research.

PurposeThe aim of this study is to examine the existing literature on service robots in order to identify prominent themes, assess the present state of service robotics research and highlight the contributions of seminal publications in the business, management and hospitality domain.Design/methodology/approachThis study analysed 332 Scopus papers from 1985 to 2022 using bibliometric techniques like citation and co-citation analysis.FindingsThe study findings highlighted that there has been a consistent rise in publications related to service robots. The paper identifies three significant themes in the service robot literature: adoption of service robots in the context of customer service, anthropomorphism and integration of artificial intelligence in robotic service. Furthermore, this study highlights prominent authors, journals, institutions and countries associated with research on service robots and discusses the future research opportunities in this domain.Originality/valueThis study contributes to the service robots’ literature in the hospitality context by compilation of various reference materials using a comprehensive bibliometric analysis. Previous studies do not point out crucial themes in this area, nor do they provide an overview of prominent journals, institutions, authors and trends in this field. Therefore, this study attempts to fill the lacunae.
