Extracting keyphrases from text document

 To extract keyphrases from a text document you must use RESTFull services.

RESTFull

public class SummarizationDocument implements Serializable {
    private static final long serialVersionUID = 1L;

    private String body = "";
    private boolean forceToLowerCase = false;

    public String getBody() {
        return body;
    }

    public void setBody(String body) {
        this.body = body;
    }

    public boolean isForceToLowerCase() {
        return forceToLowerCase;
    }

    public void setForceToLowerCase(boolean forceToLowerCase) {
        this.forceToLowerCase = forceToLowerCase;
    }

    @Override
	public String toString() {
        StringBuilder sb = new StringBuilder();
        sb.append("{");
        sb.append("body=").append(body.length());
        sb.append(",forceToLowerCase=").append(forceToLowerCase);
        sb.append("}");
        return sb.toString();
    }
}
