__init__(word_fd, quadgram_fd, ii, iii, ixi, ...) |
Construct a QuadgramCollocationFinder, given FreqDists for appearances of words, bigrams, trigrams, two words with one word and two words between them, three words with a word between them in both variations. |
above_score(score_fn, min_score) |
Returns a sequence of ngrams, ordered by decreasing score, whose scores each exceed the given minimum score. |
apply_freq_filter(min_freq) |
Removes candidate ngrams which have frequency less than min_freq. |
apply_ngram_filter(fn) |
Removes candidate ngrams (w1, w2, ...) where fn(w1, w2, ...) evaluates to True. |
apply_word_filter(fn) |
Removes candidate ngrams (w1, w2, ...) where any of (fn(w1), fn(w2), ...) evaluates to True. |
from_documents(documents) |
Constructs a collocation finder given a collection of documents, each of which is a list (or iterable) of tokens. |
from_words(words[, window_size]) |
|
nbest(score_fn, n) |
Returns the top n ngrams when scored by the given function. |
score_ngram(score_fn, w1, w2, w3, w4) |
|
score_ngrams(score_fn) |
Returns a sequence of (ngram, score) pairs ordered from highest to lowest score, as determined by the scoring function provided. |
