Example #1

File: main.py Project: jeffreyfei/kontex

def get_sentence_keyword_score(document, num_sentences):
    rake = Rake()
    keywords = rake.get_keywords(document)
    ranked_keywords = rake.generate_keyword_rank(keywords)
    sufficient_keywords_length = int(math.ceil(len(ranked_keywords) / 4.0))
    sufficient_keywords = ranked_keywords[:sufficient_keywords_length]
    total_keyword_score = 0.0
    # value of a keyword is its relative score value divided by the score of all keywords
    sentence_keyword_score = [0.0] * num_sentences
    for keyword in sufficient_keywords:
        total_keyword_score += keyword['score']
    for keyword in sufficient_keywords:
        sentence_keyword_score[
            keyword['sentence_num']] += keyword['score'] / total_keyword_score
    return sentence_keyword_score
