Big Data and Data VerificationWhat does big data mean to Internews?
What is Big Data?
In information technology, big data is a collection of data sets so large and complex that it becomes difficult to process using “normal” database management tools or traditional data processing applications. The challenges of processing this data include how to capture, to curate, to storage, to search, to share, to analyze, and to visualize it. The appeal to use larger data sets is driven by the additional information available from analysis of a single large set of related data, as compared to separate smaller sets with the same total amount of data, allowing correlations to be found to spot trends, determine quality of research, run preventive analysis, spot correlations, model risks, and determine real-time impacts of events.

The question is not if we can verify crowdsourced information or use big data in our work, the question is how do we make the verified data actionable, timely
and relevant for decision makers
