Reliable Coordination Patterns in Cyber-Physical-Social Systems

Abstract

Human's computation power can be harnessed using the so-called Cyber-Physical-Social System (CPSS), which contains a mix of human-based and machine-based compute units. The inherent problem of human-based computation is its exposure to inevitable human errors; hence, it is not trivial to obtain a reliable CPSS. In contrast, many works for obtaining reliable machine-based system have been carried out for decades. In this paper, we employ the concept of reliability in CPSSs, and exemplify the concept in the context of data analytic scenarios. We present typical coordination patterns of such CPSSs, and study the reliability of different patterns using our existing reliability analysis framework. We experiment with several different coordination patterns of machine-based and human-based compute units in data analytic scenarios and study how certain patterns may potentially increase the reliability of the CPSS.
