Boilerpipe - How do I output JSON?

Question

I am using boilerpipe and it seems great, but I want to output JSON. I am using the Java version and testing in NetBeans as follows:

final URL url = new URL("http://mashable.com/2012/09/26/worlds-best-father-kickstarter-calendar");
System.out.println(ArticleExtractor.INSTANCE.getText(url));

Can anyone tell me how I go about this?

Boilerpipe does not come with a JSON serializer.

You can, however, do this (assuming you already extracted all data):

public String articleTextToJson(String article, String title, String sourceUrl) {
    if (null == article) {
        return "{ \"error\" : { " +
               "       \"message\" : \"Article did not extract\", " +
               "       \"code\" : 1 " +
               "    }, " +
               "  \"status\" : \"error\" " +
               "}";
    }
    return "{ \"response\" : { " +
           "       \"title\" : \"" + title + "\" " +
           "       \"content\" : \"" + article + "\", " +
           "       \"source\" : \"" + sourceUrl + "\" " +
           "    }, " +
           "  \"status\" : \"success\" " +
           "}"
}

The tricky part will be of course getting the title...

Or better yet use some JSON serializer like JSONObject.

Hope that helps.
