Methodology for Assessment of Linked Data Quality

Anisa Rula, Amrapali Zaveri
2014 International Conference on Semantic Systems  
Moreover, the ability to assess the quality of the consumed LD, based on the satisfaction of the consumers' quality requirements, significantly influences usability of such data for a given use case.  ...  In this paper, we propose a data quality assessment methodology specifically designed for LD. This methodology consists of three phases and six steps with specific emphasis on considering a use case.  ...  In a comprehensive survey [12] , it was observed that in the 30 identified approaches, there were no standardized set of steps that were followed to assess the quality of a dataset.  ...
