SnowNLP的伪代码

以下是SnowNLP的一些主要功能的伪代码示例：

1. 中文分词

import jieba

def chinese_segmentation(text):
    # 将文本进行中文分词
    seg_list = jieba.cut(text, cut_all=False)
    # 返回分词结果
    return " ".join(seg_list)

2. 情感分析

from snownlp import SnowNLP

def sentiment_analysis(text):
    # 将文本传入SnowNLP进行情感分析
    s = SnowNLP(text)
    # 返回情感分析结果
    return s.sentiments

3. 关键词提取

from snownlp import SnowNLP

def keyword_extraction(text, topK=10):
    # 将文本传入SnowNLP进行关键词提取
    s = SnowNLP(text)
    # 返回前topK个关键词
    return s.keywords(topK)

4. 文本分类

from snownlp import SnowNLP

def text_classification(text, categories):
    # 将文本传入SnowNLP进行文本分类
    s = SnowNLP(text)
    # 计算文本与各个类别的相似度
    similarities = {}
    for category in categories:
        similarities[category] = s.sim(category)
    # 返回相似度最高的类别
    return max(similarities, key=similarities.get)
