NLTK & Chatbots


Notes:

  • The ‘lemmatize’ feature of NLTK not only used to convert plural into singular, it is also used before querying ConceptNet, so that the query is more likely to be successful.
  • Then the stemmed set of words is subjected to the Stanford NLTK parser, that is part of the open source NLTK suite.
  • To parse ordinal references, we use a semantic grammar augmented with features, parsed by the Earley feature chart parser from the NLTK.
  • In order to measure these proportions we have used part-of-speech tagger (pos-tagger) available in nltk toolkit.
  • However, since we required more rigorous processing of the input we used the NLTK (Natural Language Toolkit) package to parse and POS-tag the input.
  • Technically, these steps (except the first) are based on open-source library and free NLTK (Bird et al. 2009) which offers many features of language processing and has interfaces with databases such as WordNet (Fellbaum 2005) as well as with libraries and third party software such as grammatical tagger Stanford Tagger and automated prover prover9.
  • In addition, users can access Semantic Pathways via a command-line interface, where integration with Python and NLTK offers additional benefits.
  • Grapevine is built in Python using the Natural Language Tool Kit (NLTK).
  • Corpus-Based Evaluation of Prosodic Phrase Break Prediction Using nltk_lite’s Chunk Parser to Detect Prosodic Phrase Boundaries in the Aix-MARSEC Corpus of Spoken English
  • The probablistic reasoning described in the previous section was implemented with the Natural Language Toolkit (NLTK).
  • We adapted computational tools to generate structured representation of actions by external tags (VISL) inside the package Natural Language Toolkit (NLTK).
