“Listens to signals” for a domain.
Obtains patterns (meaning) from the signals:
– detects and scores the strength of the signal features;
– learns which features are meaningful.
Determines confidence by analyzing supporting evidence.
Uses trained machine learning:
– previously trained against data that represents domain ground truth.
Elevates and amplifies human cognition:
– Exploration, engagement, discovery, enforcement, and decision support

IBM Watson
Differences with Programmatic Computing
Learned behavior:
– rather than being instructed via program or rules; and so
– less brittle to change than programmed systems.
Behavior adapts over time according to:
– on-going experience; and
– exposure to new information.
… These systems need LOTS of training data to achieve
human proficiency
– initially and through on-going experience.

A 58-year-old woman presented to her primary care physician after several days of dizziness, anorexia, dry mouth, increased thirst, and
frequent urination. She had also had a fever and reported that food would “get stuck” when she was swallowing. She reported no pain
in her abdomen, back, or flank and no cough, shortness of breath, diarrhea, or dysuria. Her family history included oral and bladder
cancer in her mother, Graves' disease in two sisters, hemochromatosis in one sister, and idiopathic thrombocytopenic purpura in one
sister. Her history was notable for cutaneous lupus, hyperlipidemia, osteoporosis, frequent urinary tract infections, three
uncomplicated cesarean sections, a left oophorectomy for a benign cyst, and primary hypothyroidism, which had been diagnosed a
year earlier. Her medications were levothyroxine, hydroxychloroquine, pravastatin, and alendronate. A urine dipstick was positive for
leukocyte esterase and nitrites. The patient was given a prescription for ciprofloxacin for a urinary tract infection and was advised to
drink plenty of fluids. On a follow-up visit with her physician 3 days later, her fever had resolved, but she reported continued weakness
and dizziness despite drinking a lot of fluids. She felt better when lying down. Her supine blood pressure was 120/80 mm Hg, and her
pulse was 88 beats per minute; on standing, her systolic blood pressure was 84 mm Hg, and her pulse was 92 beats per minute. A urine
specimen obtained at her initial presentation had been cultured and grew more than 100,000 colonies of Escherichia coli, which is
sensitive to ciprofloxacin.

Personality Insights
Enables deeper understanding of people's personality
characteristics, needs, and values to help engage users
on their own terms
The IBM Watson Personality Insights service uses linguistic analytics to infer cognitive
and social characteristics, including Big Five, Values, and Needs, from communications
that the user makes available, such as email, text messages, tweets, forum posts, and
more. By deriving cognitive and social preferences, the service helps users to
understand, connect to, and communicate with other people on a more personalized
level.
“My words” show my personality.
“Big 5” Traits:
– openness;
– conscientiousness;
– extraversion;
Calibrated with standard tests.
– agreeableness;
– neuroticism; and
– 47 others.

Concept Insights
Explores information based on the concepts behind your
input, rather than limiting investigation to findings based
on traditional text matching
The Concept Insights service maps user-input words to the underlying concepts of those
words based on training on English Wikipedia data. Doing so can broaden the user's
investigation beyond the actual words used in an inquiry. Two types of associations are
identified: explicit links when an input document directly mentions a concept, and implicit
links which connect the input documents to relevant concepts that are not directly mentioned
in them. Users of this service can also search for documents that are relevant to a concept
or collection of concepts by exploring the explicit and implicit links.
Link words between documents and concepts
Explicit linkage when a document names a concept
Implicit linkage when concept indirectly mentioned

Natural Language
Classifier
Interpret natural language and classify it with confidence
The IBM Watson Natural Language Classifier service enables developers without a background
in machine learning or statistical algorithms to create machine-learning, natural language
interfaces for their applications. The service interprets input text (questions or other) and returns
a corresponding classification with associated confidence levels. The return value can then be
used to trigger a corresponding action, such as redirecting the request or answering the
question.
