Output: NTLK document corpus (NLTK document corpus name)Įxample usage: POS tagger intrinsic evaluation - experiment 2 ‘^1000’ will discard first 1000 sentences of the corpus and return the rest of the corpus.) For example ‘^80%’ will discard first 80% of the corpus and return last 20% of the corpus. You can also define the chunk you want to discard. For example, value ‘1000’ will return first 1000 sentences in the corpus. ‘80%’) of the corpus you would like or you can define the number of sentences from the beggining of the corpus. You can define the chunk as percentage(e.g. Parameter: Corpus Chunk (Define the chunk of the corpus you want. ![]() Parameter: NLTK Document Corpus Name (NTLK Document Corpus Name) Parsed_paras(): list of (list of (Tree with str leaves)) Parsed_sents(): list of (Tree with str leaves) Tagged_paras(): list of (list of (list of (str,str)))Ĭhunked_sents(): list of (Tree w/ (str,str) leaves) Tagged_sents(): list of (list of (str,str)) ![]() Install corpora using nltk.download().Ĭorpus has the following available functions: These functions can be used to read both the corpus files that are distributed in the NLTK corpus package, and corpus files that are part of external corpora. The modules in this package provide functions that can be used to read corpus files in a variety of formats.
