The Four ‘V’s of Big Data

Recently, the NSA was accused of a giant wiretapping operation that targets U.S. citizens. The nature of the operation came to light after Edward Snowden, a former employee of an NSA contractor, revealed information regarding the widespread wiretapping to the press. The leaked information described how the NSA has been monitoring communications between the US and foreign nationals over the internet for a number of years, under a project called PRISM. Some of the biggest internet companies, from Apple to Google to Yahoo, are allegedly involved. The U.S. government has since confirmed the existence of the scheme and its applications.

All of the data being monitored and collected is what’s known as “big data.” This includes data that can be pulled from multiple media sources including climate change sensors, social media site postings, digital pictures and videos, cell phone GPS signals and just about anything that can be transmitted or aggregated through the internet. According to IBM, the facets of big data covers four areas: volume, velocity, variety and veracity.

  • Volume – Big data wouldn’t be “big” if there wasn’t a volume factor. It’s easy to amass terabytes and sometimes even pentabytes of data when harvesting it.
  • Velocity describes the time sensitivity of big data, like using that data to prevent fraud or certain acts.
  • Variety is the part of big data where various media sources such as pictures, video and audio can be used together to gain new insights.
  • Veracity covers the amount of trust in the information gathered from big data. It’s hard to put the insights gained from big data to use if you don’t trust the information it is providing.

The NSA’s program PRISM dealt with big data allegedly in an attempt to stop terrorist plots before they happened. Market researchers use their own version of ‘big data’ all the time –quantitative surveys, segmentations and other methodologies. At Observation Baltimore, we help clients understand the “how” and “why” the Big Data so that they can make decisions that propel them and their client’s businesses forward.

The usage of this data is much the same as many other big data collectors. The data is classified and categorized to identify patterns from which companies can gain big insight. Observation Baltimore also utilizes many other big data gathering methods such as telephone interviews and in-depth video interviews.

Observation Baltimore has been serving the Baltimore market research industry for two decades.
