Cognitive computing: The solution for big data information overload

Big data, it is a term that people in general vaguely know but are contributing to on a daily basis. Every day we create around 2.5 quintillion bytes of data. Of this data, 90% has been created in the last two years alone. The data is collected in a lot of different ways: sensors, shared digital pictures and videos, posts on social media sites, purchase transaction records, GPS signals and so on. The growth of data is exponential, becoming more and more rapid every year. A big part of this information remains private and of no real value. Still there is a lot of data left to analyse and as more and more objects are becoming smart and connected this amount of data will grow even faster.

This collected data can be of great value in a lot of areas like research, business or public services. The problem however is that there is so much data available that we aren’t able to cope with it. It is estimated that around 33% of all the data in the ‘digital universe’ contains information that could be valuable if it is analysed. However only 0.5% of this data is looked at. The main reason is that almost all the big data available (97%) is not structured. It is just raw data which the computer systems are not able to label and structure and make it useable.

IBM is aware of this growing problem and thinks it has the answer. It is developing and building ‘cognitive computers’. These computers will are able to understand natural language, learn about context, structure and meaning and even analyse images and video. This makes them ideal for analysing huge volumes of data. It already has a cognitive computing system called Watson, that is already very impressive and doing research in different areas. IBM’s Dr John E. Kelly III says that the cognitive computing system is able to make sense of 80% of the data that is labelled ‘unstructured’ by computer scientists.

While we as human beings not have the processing power to handle constant huge amounts of data, cognitive computing does. It is therefore able to help us move forward in a lot of different ways using big data. From developing better healthcare settings to combining sales data and social media for marketing purposes to even helping local authorities combat crime. The system is effectively giving us the information we need to make the right choice and to use the right information for the best.

The Best Doctor in the World 3.67/5 (3)

You might know IBM’s supercomputer Watson for being the world Jeopardy! champion. Still dubbed a “question answering machine” in 2011, nowadays the computer went to medical school to become the world’s best diagnostician: Just a few years ago Watson was already about 42% better at diagnosing illnesses and prescribing effective treatments than its human counterparts. And with the Watson only costing $189 versus $497 for a human doctor for the same result, is it time to replace your physician now?

Before answering that question, let us first take a look at what makes Watson so suitable to replace a human doctor. Andrew McAfee, a research scientist at MIT, wrote about the following aspects on his blog:

  • It is based on all available knowledge: theoretically Watson could have access to all medical literature and databases with medical imagery such as X-ray images and the like, plus all other information sources that could be of use in diagnosing. Additionally, the best thing is that Watson can access these sources at any time while never forgetting or overlooking anything.
  • It is consistent: Watson always reports the same diagnosis with the same inputs. Besides, Watson is never sick, upset, or sleep deprived. What is more is that this computer also knows what it does not know : in case of a low confidence in its own diagnosis Watson will report and call in a human to take over.
  • It is accessible: Watson has low marginal costs. The initial investment to build and train Watson is still high, yet once functioning each diagnosis is less expensive than when performed by a medical professional. Besides, Watson can be accessed from anywhere in the world by using a computer or mobile phone.

Now that we have seen the benefits of Watson, it is probably a good idea to increase the computer’s involvement in diagnosing. However, according to Gerard Smit, chief intelligence officer at IBM, Watson will never replace a human doctor: it has merely been designed to enhance the interaction between man and machine (KIJK, April 2016, p. 20). That is probably the right answer to the question whether to fully replace your doctor (already) as Watson is (still) lacking certain features such as the social aspects of consulting a physician.
