The function and role of AI in collaborating in future work scenarios has received a great deal of attention across industries, but there has been limited work on assessing the current state of research on human-AI collaboration and integrating research results. To fill this gap, we conducted a systematic review of 43 research papers on human-AI collaboration in the field of Information Systems. Our analysis focuses on conceptualization of human-AI collaboration, collaboration mechanism, human and AI characteristics in the literature. Based on the findings, we developed a conceptual framework that highlights the interrelationships between the four parts. Finally, we identify research gaps and propose future research directions for further exploration in this expanding research area.
