DeepDive

DeepDive is a system to extract value from dark data ( Gartner defines dark data as the information assets organizations collect, process and store during regular business activities, but generally fail to use for other purposes (for example, analytics, business relationships and direct monetizing). Similar to dark matter in physics, dark data often comprises most organizations’ universe of information assets. Thus, organizations often retain dark data for compliance purposes only. )  and put the results into a database. With the data in a database, one can use a variety of standard tools that consume structured data; e.g., visualization tools like Tablaeu or analytics tools like Excel.
