Abstract

Crowd computing is a term that has been used only recently in the literature, and has been conceptualised in various ways as being related to crowdsourcing, human computation, social computing, cloud computing and mobile computing. This literature lacks a common definition of crowd computing, and emerging technologies with somewhat similar uses have added to the conceptual confusion. Whilst some authors have referenced work by other scholars and a few have attempted to provide a definition of crowd computing, it appears that the multiple streams of research and definitions have evolved somewhat independently, perhaps due to the relative newness of this area of research. This paper reconciles and integrates the various descriptions of crowd computing within the extant literature, in order to propose a definition of crowd computing which can be used to position the research already conducted on this subject, and can be used as a starting point for further research. Crowd computing has been described in various ways including distribution of human intelligence tasks to mobile devices, cloud computing with humans, human problem solving with large numbers of people using computers, and broadly as a set of human interaction tools for idea exchange and non-hierarchical decision making. From the literature four common characteristics can be identified to define the boundaries of the term, i.e.: participation by a crowd of humans, interaction with computing technology, activity that is predetermined by the initiator or application itself and the execution of tasks by the crowd utilising innate human capabilities.
