Watson is an artificially intelligent computer system capable of answering questions posed in natural language, developed in IBM's DeepQA project. Watson is a cognitive technology that processes information more like a human than a computer—by understanding natural language, generating hypotheses based on evidence and learning as it goes.

2. WATSON
 Artificially intelligent computer system
 Capable of answering questions posed in natural language
 Developed in IBM's DeepQA project
 Watson was named after IBM's Thomas J. Watson.

3. Actually, What is it?

4. Actually, What is it?
 question answering (QA) computing system
 advanced natural language processing
 information retrieval
 knowledge representation
 automated reasoning
 machine learning technologies
 to the field of open domain question answering

5. Hardware
 workload optimized, integrating massively
parallel POWER7 processors and being built on
IBM's DeepQA technology
 composed of a cluster of ninety IBM Power 750 servers,
each of which uses a 3.5 GHz POWER7 eight core
processor, with four threads per core
 In total, the system has 2,880 POWER7 processor
cores and is able to store 16 terabytes of RAM

6. Hardware
 Watson can process 500 gigabytes, the equivalent of a
million books, per second
 Watson's hardware cost at about $3 million and with
80 TeraFLOPs
 the content was stored in Watson's RAM for the
operation because data stored on hard drives are too
slow to access

9. Software
 written in various languages
 Java, C++, Prolog, etc
 Apache Hadoop framework for distributed computing,
Apache UIMA (Unstructured Information
Management Architecture) framework
 IBM’s DeepQA

10. Software
 SUSE Linux Enterprise Server 11 operating system
 more than 100 different techniques
 analyze natural language
 identify sources
 find and generate hypotheses
 find and score evidence
 merge and rank hypotheses

11. DATA
 Sources of information include encyclopaedias,
dictionaries, thesauri, newswire articles, and literary
works.
 Watson also used databases, taxonomies, and
ontologies.
 DBPedia, WordNet, Yago
 Millions of information and data - to build its
knowledge.

14. First Implementation
 Watson competed on Jeopardy! against former
winners Brad Rutterand Ken Jennings
 Watson received the first prize of $1 million

16. Current Implementation
 Watson software system's first commercial application
would be for utilization management decisions
 Lung cancer treatment at Memorial Sloan–Kettering
Cancer Center in conjunction with health insurance
company WellPoint
 IBM Watson’s business chief Manoj Saxena says that
90% of nurses in the field who use Watson now follow
its guidance

17. WATSON at Health Care

18. Future Implementation
 Rensselaer Polytechnic Institute will receive a
successor version of Watson
 at the Institute's technology park – for researchers and
students
