What is BlueMix?

• Bluemix is an open-standard, cloud-based platform for building,

managing, and running applications of all types (web, mobile, big

data, new smart devices, and so on).


Instant EnvironmentsThe developer can choose any

language runtime or bring your own.

Zero to production in one command.

APIs and ServicesA catalog of IBM, third party, and open

source API services allow the

developer to stitch an application

together in minutes.

On-Prem IntegrationBuild hybrid environments. Connect to

on-premise assets plus other public

and private clouds.

DevOpsDevelopment, monitoring, deployment,

and logging tools allow the developer to

run the entire application.

Layered SecurityIBM secures the platform and

infrastructure and provides you with the

tools to secure your apps.

Flexible PricingSign up in minutes. Pay as you go and

subscription models offer choice and

flexibility.

Why are developers using BlueMix?


Go from zero to running code in a

matter of minutes

Automate the development and

delivery of many applications

To rapidly bring products

and services to market at

lower cost

To continuously deliver

new functionality to their

applications

To extend existing

investments in IT

infrastructure

Extend existing investments by

connecting securely to on-

premise infrastructure


Watson Platform Services

10

A cognitive learning system enhances our abilities to perceive, reason and relate.


Perception:

Watson understands the world as we do: it interprets sensory input beyond traditional data

Reasoning:

Watson thinks through complex problems: it deepens our analysis and inspires creativity

Relating:

Watson understands how we communicate, and personalizes its interactions with each of us

Learning:

Watson learns from every interaction, scaling our ability to build experience


User Modeling

Psycholinguistic

Analytics

• User Modeling leverages linguistic analytics to construct

a personality profile of an individual based on their

social footprint and other written artifacts.

• The generated profile includes personality and

social traits, values, needs and the Big 5

personality traits

• Openness

• Conscientiousness

• Extraversion

• Agreeableness

• Neuroticism

12

User Modeling

Input: The application provides text input

generated by the individual: emails, tweets, blogs

and other text documents.

Portrait API: JSON object of cognitive and social

characteristics

Visualization API: Uses Portrait API output to

generate a visual portrait© 2014 International Business Machines Corporation


Language Identification

Analyzes text and identifies the primary language

of the text.

Input: UTF-8 formatted text Output: IETF language tag

中國哲學書電子化計劃

zh-TW



Machine Translation

Provides an API to translate text between

languages.

Input: REST service call

that contains text and the

translation engine to use.

Output: Translated text

Supports English, Spanish, Brazilian Portuguese and French.



Relationship Extraction

Analyzes text and identifies relationships

between sentence components.



Relationship Extraction

Input: Text to analyze,

model, output format

Output: Extracted

relationships in text, json or

xml format.

Supports English and Spanish language news models.


17

Question Answer

Leverages NLP to understand user

questions and provides answers,

evidence and associated confidence.

The Question Answer service is a

gateway to BlueMix-hosted Travel and

Healthcare domain corpora.

Understands question

Produces possible answers and

evidence

Analyzes evidence

Computes confidence

Delivers response, evidence and

confidence

Asks a question

Considers response and

evidence



Question Answer Question Answer

Input: A QA API formatted question{ question: {

questionText: “Should I take aspirin on a daily basis?”

}}

Output: QA API JSON response with

answers, evidence and confidence

levels.

Question Answer - QAAPI




The Watson for Travel corpus contains content from the

following sources:

•Wikivoyage

•CDC Travel

•TSA.gov

Question Answer - Travel




The Watson for Healthcare corpus is populated from the

following sources:

•Healthfinder.gov

•CDC Health Topics

•National Heart, Lung, and Blood Institute (NHLBI)

•National Institute of Arthritis and Musculoskeletal and

Skin Diseases (NIAMS)

•National Institute of Diabetes and Digestive and Kidney

Diseases (NIDDK)

•National Institute of Neurological Disorders and Stroke

(NINDS)

•Cancer.gov (physician data query)

Question Answer - Healthcare



Concept Expansion

Concept Expansion is a process that is also known as Semantic Lexicon

Induction, or Semantic Set Expansion. It is the process by which a

semantic class, such as fruit goes from a list of terms like "apple, orange,

cherry" to "apple, orange, cherry, limes, strawberries".

Analyzes text and compares it to a set of

unstructured data to extract similar concepts.



Input: List of words to

expand and a corpus id

Output: List of expanded

concept with prevalence in

corpus

Concept Expansion

Hematoma, medtrans



Message Resonance

Analyzes content and scores how well the

message is to be received by a target

community.



Message Resonance

Input: Content to analyze

and a corpus identifier

Output: JSON object with

resonance rankings

Supports Cloud Computing and Big Data communities



Visualization Rendering

Visualization Rendering in an SDK that drives

data visualization using JSON.

Charts are created using a set

of composable features

Infinite chart flexibility - one

chart widget may handle many

chart specifications

Supports Java, JavaScript, iOS and Android© 2014 International Business Machines Corporation

Feedback Tools


Each service provides a feedback mechanism in order to learn from the

community.

The feedback is PUT to the

service in JSON format.

Services leveraging this feedback

mechanism:

• User Modeling

• Concept Expansion

• Machine Translation

• Relationship Extraction

• Language Identification

27

Feedback Tools


The Question Answer service also has a Feedback API, of which the feedback is

used by Watson to increase precision and accuracy.
