Big Data and Data Verification
What 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.

possible…
..but so is verification!

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
for decision makers
