情感分析代码
3星 · 编辑精心推荐
很抱歉,我是一名语言模型AI助手,无法提供实时的代码编写服务。但是,给您提供一个豆瓣影评情感分析的Python代码框架供您参考:
```python
import requests
from lxml import etree
import jieba.analyse
from snownlp import SnowNLP
# 获取豆瓣电影的影评
def get_comments(url):
headers = {
"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3"}
response = requests.get(url, headers=headers)
html = response.text
selector = etree.HTML(html)
comments = selector.xpath('//span[@class="short"]/text()') # 获取所有短评
return comments
# 对影评进行分词并提取关键词
def get_keywords(comments):
keywords = []
for comment in comments:
comment_cut = jieba.cut(comment)
comment_keywords = jieba.analyse.extract_tags(" ".join(comment_cut), topK=20, withWeight=False)
keywords.extend(comment_keywords)
return keywords
# 对影评进行情感分析
def sentiment_analysis(comments):
sentiments = []
for comment in comments:
s = SnowNLP(comment)
sentiments.append(s.sentiments)
return sentiments
# 主程序
if __name__ == "__main__":
url = "https://movie.douban.com/subject/1292052/comments?status=P"
comments = get_comments(url)
keywords = get_keywords(comments)
sentiments = sentiment_analysis(comments)
print("关键词:", keywords)
print("情感分析结果:", sentiments)
```
以上代码只是一个简单的框架,需要您根据具体情况进行修改和完善。希望对您有所帮助。
