... is labeled for each particular verb as so-called frames. Addition- ally, semantic roles can also be labeled with one of 13 ARGM adjunct labels, such as ARGM-LOC or ARGM-TMP for additional locational ... locational or temporal information relative to some verb. Shallow semantic parsing has immediate applica- tions in tasks such as meta-data extraction (e.g. from web documents) and questi...

... evaluated against a gold standard containing up to 10 possible paraphrases for each of the individual instances. There are two natural subtasks in generating paraphrases: identifying paraphrase ... Experiments: Ranking Paraphrases In this section, we evaluate our model on a para- phrase ranking task. We consider sentences with an occurrence of some target word w and a list of paraphrase...
