A Java wrapper for the IBM Watson DQA service.
The latest release is jwatson 1.0.
Use sbt clean compile assembly to build the project. The fat jar file can be found in the /target folder.
public static void main(String[] args) throws IOException {
// Create a Watson instance with your URL and credentials
JWatson watson = new JWatson("username", "password", "https://url/instance/xxxxx/deepqa/");
// Query Watson to retrieve answers for a specific question
// WatsonAnswer answer = watson.askQuestion("Who is Angela Merkel?");
// ... or use the QuestionBuilder to construct complex questions for Watson
WatsonQuestion question = new WatsonQuestion.QuestionBuilder("Who is Angela Merkel?")
.setNumberOfAnswers(3) // Provide three possible answers
.formatAnswer() // Instruct Watson to deliver answers in HTML
.create();
WatsonAnswer answer = watson.askQuestion(question);
System.out.println(answer);
} - Make sure that the URL contains a trailing slash at the end.
- Ping and Feedback endpoints are not implemented yet.
- To use JWatson with the Bluemix QA service instead of an university (private-) instance, you need make slightly modifications in the JSON structure.
