<p>D&eacute;riF is not a lemmatizer, but a rule-based morphosemantic analyser for French, i.e. it provides both derived and compounds words with their complete morphological analysis. D&eacute;riF's input must be a POS tagged lemma X. D&eacute;riF's output is a morphological description of X, including :</p> <ul> <li>its set of ancestors (= its 'direct' morphological family)</li> </ul> <p style=\"margin-left: 30px;\">ex:</p> <p style=\"margin-left: 30px;\"><em>intoxication/N : (intoxication/N, intoxiquer/V, toxique/A)</em></p> <p style=\"margin-left: 30px;\">[intoxication, intoxicate, toxic)</p> <ul> <li>its definition, according to the meaning of its base and the Word Formation rule relating X and this base:</li> </ul> <p style=\"margin-left: 30px;\">ex:</p> <p style=\"margin-left: 30px;\"><em>h&eacute;patique/A</em> =&gt; \"Related to the liver\"</p> <ul> <li>a set of morphology-predicted lexical semantic annotations</li> </ul> <p style=\"margin-left: 30px;\">ex:</p> <p style=\"margin-left: 30px;\"><em>laver/V</em> [wash] =&gt; [ aspect=dynamic, subcat = &lt; NPagent, NPpatient &gt; ]</p> <p>Further details about D&eacute;rif in :</p> <p>Namer, Fiammetta. 2009.
