Searching for Dark Data by Paul Doscher.

From the post:

We live in a highly connected world where every digital interaction spawns chain reactions of unfathomable data creation. The rapid explosion of text messaging, emails, video, digital recordings, smartphones, RFID tags and those ever-growing piles of paper – in what was supposed to be the paperless office – has created a veritable ocean of information.

Welcome to the world of Dark Data

Welcome to the world of Dark Data, the humongous mass of constantly accumulating information generated in the Information Age. Whereas Big Data refers to the vast collection of the bits and bytes that are being generated each nanosecond of each day, Dark Data is the enormous subset of unstructured, untagged information residing within it.

Research firm IDC estimates that the total amount of digital data, aka Big Data, will reach 2.7 zettabytes by the end of this year, a 48 percent increase from 2011. (One zettabyte is equal to one billion terabytes.) Approximately 90 percent of this data will be unstructured – or Dark.

Dark Data has thrown traditional business intelligence and reporting technologies for a loop. The software that countless executives have relied on to access information in the past simply cannot locate or make sense of the unstructured data that comprises the bulk of content today and tomorrow. These tools are struggling to tap the full potential of this new breed of data.

The good news is that there’s an emerging class of technologies that is ready to pick up where traditional tools left off and carry out the crucial task of extracting business value from this data.

Effective exploration of Dark Data will require something different from search tools that depend upon:

  • Pre-specified semantics (RDF) because Dark Data has no pre-specified semantics.
  • Structure because Dark Data has no structure.

Effective exploration of Dark Data will require:

Machine assisted-Interactive searching with gifted and grounded semantic comparators (people) creating pathways, tunnels and signposts into the wilderness of Dark Data.
