在多标签分类Python中预处理数据

Question

My dataset structure:

Text: 'Good service, nice view, location'
Tag: '{SERVICE#GENERAL, positive}, {HOTEL#GENERAL, positive}, {LOCATI
ON#GENERAL, positive}'

And the point here is that I don't know how can I structure my data frame. If you have any recommendations, these will be really nice to me. Thank you.

Answer 1

Separate adjectives (good, bad, etc) from the hotel attributes (service, view, location). You can start from creating a custom dictionary and automatically detect and leverage new words as categories. You could use some name entity recognition to do so, here some articles:

Personally I have used the standford one, pretty cool
