关键词快速匹配范例

   在进行文本分类时，仅仅依靠模型是得到满意的效果，需要结合关键词提高精度，一个例子如下：

df = pd.read_excel(file_name, encoding='utf8')
text = df.values.tolist()
# key_words = ['牛肉','猪肉','鸡肉']
key_words = ['野鸡','野兔', '野生动物']
res = []
with open('./data/data_2020.txt', 'w', encoding='utf8') as fw:
    for i, each in enumerate(text):
        data = []
        for c in each:
            if isinstance(c, str):
                data.append(c)
        to_write = data[0]
        if len(to_write) >= 5 and len(to_write) <= 150:
            # 如果里面包括关键词：
            if any((to_write.find(k) != -1) for k in key_words):
                print(to_write)
                res.append(to_write.strip()+'\n')

    fw.writelines(res)
