Our aligner improves F1 score by 2 to 5% with LVCs information. Moreover, the resulting AMR parser achieves the best Smatch scores among other transition-based AMR parsers. We also show that the RevNN framework helps to integrate different linguistic features for improvement in accuracy of ...
Part of NLP Collective 0 I want to extract nounphrases from text and i use python with NLTK. There is a pattern I found in internet of using RegexpParser as follows: grammar = r""" NBAR: {<NN.*|JJ>*<NN.*>} # Nouns and Adjectives, terminated with Nouns NP: {<NBAR>} {<NBAR...
