1 How powerful is Watson Describe its technology Why does it

1. How powerful is Watson? Describe its technology. Why does it require so much powerful hardware? 2. How “intelligent” is Watson? What can it do? What can’t it do?

Solution

Answer :

    Watson is a technology platform that uses natural language processing and machine learning to reveal insights from large amounts of unstructured data.

1.Watson consists of 10 racks of IBM Power 750 servers running Linux,uses 15 terabytes of RAM and 2880 processor cores,and operates at 80 teraflops.

2.Watson needed this amount of power to quickly scan its enormous database of information,including information from the Internet.

3.Watson is able to learn from its mistakes as well as its successes.To slove a typical problem,Waston tries many of the thousands of alogrithms that the team has programmed it to use.

4.The Algorithms evaluate the language used in each clue,gathering the information about the important people and places mentioned in the clue,and generate hundreds of solutions.

5.It uses a natural language processing,information retrieval,knowledge representation,and machine learning technologies along with IBM\'s DeepQA technology for massive evidence gathering ,analysis,and scoring.

6.Watson remembers what type of question it was and the algorithm it used to get the right answer.In this way,Watson improves at answering questions over time.
