It is commonly accepted that online social networking and decision support systems are two
intertwined research fields. However, as the extent of such interconnection is still quite scarce, we
underwent a large study of these research fields, over a time-span of eight years (from 2003 until
2010).
Previous research on this matter had already determined that many concepts are encompassed by
both online social networking and decision support systems research. Due to the large number of
concepts and using clustering techniques, we were able to determine four concept clusters, namely:
the technical infrastructure, online communities, network analysis and knowledge management.
After determining the referred concept clusters, we intended to gain further knowledge on how those
concepts influenced DSS related research, specifically in terms of their actual support of the three
traditional decision-making phases, namely the intelligence, design and choice phases. Not only had
we wanted to determine the actual contribution of each cluster to the support of the phases of
decision-making process, but also we wanted to perceive the interconnections among the concept
clusters themselves, for which we used structural equation modeling techniques.
The results presented in this paper evidence that not only online social networks are being used as a
technical infrastructure to support the three decision making phases and to support knowledge
management and online communities, but also that the other clusters only regard the intelligence
phase of the decision process
