Question:
Find the most frequent bigrams
Please complete the freq_bigram function to find the ????n most frequent bigrams. Your function should return a list of top_n tuples. Each of the tuples should contain a bigram tuple (such as ('????', '????')) and its number of occurrence.
def freq_bigrams(tweets, top_n):
bigram_counter = Counter()
for tweet in tweets:
# YOUR CODE HERE
return bigram_counter.most_common(top_n)
2. Find the most frequent skipgrams
In this exercise we will compute another commonly defined type of sequential patterns -- the skip-grams. Luckily this is also supported by NLTK. You can find the documentation here.
Please implement the freq_skipgrams function to calculate the most frequently used ????k-skip-????n-grams. Your function should return a list of top_n tuples. Each of the tuples should contain a ????k-skip-????n-gram tuple (such as ('Happy', 'Birthday', '????')) and its number of occurrences.
def freq_skipgrams(tweets, n, k, top_n):
skipgram_counter = Counter()
