The document outlines the integration of IBM Watson services with a focus on their consumption via REST APIs and support through Darwino for easier access. It highlights various Watson services available and the setup process that does not require full deployment on Bluemix, only a stub application to obtain access tokens. An example of the Social Analyzer demonstrates how to use Watson's Tone Analyzer for content analysis and data handling.

1. Integrating Watson Services

2. Watson Services
• Watson services are consumed via REST APIs
• IBM provides Java wrappers for these: https://github.com/watson-
developer-cloud/java-sdk
• Darwino provides consistent access to these APIs in ways that can be used as
beans
• Darwino module dwo-jre-ibm-watson
<bean name="toneAnalyzerFactory" class="com.darwino.ibm.watson.ToneAnalyzerFactory">
<property name="url">https://gateway.watsonplatform.net/tone-analyzer/api</property>
<property name="user">some-unid-string</property>
<property name="password">some-random-password</property>
</bean>

3. Supported Services

4. Setting Up The Services
• Apps don’t actually need to
be deployed to Bluemix to
consume Watson services
• All that is required is a stub
application on Bluemix with
the services associated with
it – that will give you the
access tokens

5. Example: Social Analyzer
• The Social Analyzer uses Watson’s Tone Analysis to analyze content from
multiple sources
• Analysis is done by a periodic background task, written to find un-analyzed
documents and add in Watson’s results
ToneAnalyzer analyzer = getToneAnalyzerFactory().createToneAnalyzer();
// …
ToneAnalysis analysis = analyzer.getTone(content).execute();
if(analysis != null) {
JsonObject analysisObj = JsonObject.fromJson(analysis.toString());
document.set(PROP_ANALYSIS, analysisObj);
document.save();
}
