Big Policy Canvas Research Roadmap

[...] * Big Data Quality assessment is an important phase integrated within data pre-processing. It is a phase where the data is prepared following the user or application requirements. When the data is well defined with a schema, or in a tabular format, its quality evaluation becomes easier as the data description will help mapping the attributes to quality dimensions and set the quality requirements as baseline to assess the quality metrics.

Big Data quality assessment is an important step, that should preferably occur before, rather than during or after, data pre-processing. Hence, it constitutes an important research challenge.
