Python 简单的文本关键词提取

调用pynlpir提取top5关键词

import pynlpir
def get_nlpirkeywords(content):
    top_num = 5
    pynlpir.open()
    key_words = pynlpir.get_key_words(content, weighted=True)
    # print(key_words)
    nlpir_keywords = []
    for key_word_index in range(min(top_num, len(key_words))):
        nlpir_keywords.append(key_words[key_word_index][0])
    return nlpir_keywords

• 需要注意的是，pynlpir模块要定时更新licence，当licence失效时需要命令行执行pynlpir update
