1. Introduction
Many studies have been implemented to address big data assessing to reduce big data
assessing efforts by handling big data reliability at initial stages in the big data development life
cycle (BDDLC) [1-7]. Big data reliability (BDR) is the reliability attribute about the easiness
degree to which system’s defects can be detected at assessing phase [4]. Researches show
that more than forty percent of Big Data development efforts are spent on assessing, with the
percentage for assessing critical systems being even higher [2, 3]. The better the reliability of
particular Big Data, the lower the assessing effort required in assessing phase. Moreover, the
earlier the reliability is considered, the lower the cost of assessing phase. Big Data Structure of
Internet of Things (BDSIT) provides a high level of abstraction of Big Data represented by Big
Data modules and the connections between them. Thus, BDR should be considered at the early
phases of Big Data Development Life Cycle (BDDLC), specifically in the Big Data Structure of
Internet of Things (BDSIT) [3, 4]. Big Data Structure of Internet of Things should consider the
reliability rules while building the BDSIT in order to improve Big Data reliability.
