我有大量的 yelp 数据,我必须将评论分为 8 个不同的类别。
类别
Cleanliness
Customer Service
Parking
Billing
Food Pricing
Food Quality
Waiting time
Unspecified
评论包含多个类别,所以我使用了 multilable 分类。但我很困惑如何处理正/负。示例评论可能对食品质量有利,但对客户服务不利。Ex-food taste was very good but staff behaviour was very bad. so review contains positive food quality but negative Customer service
我该如何处理这种情况?我应该在分类之前进行情感分析吗?请帮我
