d reliability rules. In this paper, BDSIT assessment model is proposed. The assessment is
based on connection degree and relevance reliability rules. This assessment gives an indication
on the required assessing efforts for the entire Big Data. The logical reasoning system is used
to perform the assessment process based on these rules. If Big Data required significant
assessing efforts, the second phase is performed to help in improving Big Data reliability and
reducing assessing efforts. Modules’ assessment specifies the assessing efforts required for
each module. After assessing all modules, the structure can tell which module(s) required more
effort for assessing. Moreover, in this phase, each module in the BDSIT is assessed using the
logical reasoning system. This process can be iterated as long as the system and modules
functionalities are maintained. In the following sections, the proposed model is discussed in
details. Then, this module is modified to increase its reliability; consequently, the whole Big Data
