Examples

A simple keyphrase extractor with default weighting (based on Wikipedia's corpus)

import fi.metropolia.mediaworks.juju.syntax.parser.DocumentBuilder;
import fi.metropolia.mediaworks.juju.document.Document;
import fi.metropolia.mediaworks.juju.extractor.keyphrase.KeyphraseExtractor;

String input = "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nunc vitae dui lacus.";

Document document = DocumentBuilder.parseDocument(input, "fi"); // "en" is also available
KeyphraseExtractor extractor = new KeyphraseExtractor(document);

return extractor.process()

Calling process() will return a Map<Grams, Double>. Grams represent a word and the latter it's frequency/weight.
