GoEmotions Pytorch

Pytorch Implementation of GoEmotions with Huggingface Transformers

What is GoEmotions

Dataset labeled 58000 Reddit comments with 28 emotions

admiration, amusement, anger, annoyance, approval, caring, confusion, curiosity, desire, disappointment, disapproval, disgust, embarrassment, excitement, fear, gratitude, grief, joy, love, nervousness, optimism, pride, realization, relief, remorse, sadness, surprise + neutral

Training Details

Use bert-base-cased (Same as the paper's code)
In paper, 3 Taxonomies were used. I've also made the data with new taxonomy labels for hierarchical grouping and ekman.
1. Original GoEmotions (27 emotions + neutral)
2. Hierarchical Grouping (positive, negative, ambiguous + neutral)
3. Ekman (anger, disgust, fear, joy, sadness, surprise + neutral)

Vocabulary

I've replace [unused1], [unused2] to [NAME], [RELIGION] in the vocab, respectively.

[PAD]
[NAME]
[RELIGION]
[unused3]
[unused4]
...

I've also set special_tokens_map.json as below, so the tokenizer won't split the [NAME] or [RELIGION] into its word pieces.

{
  "unk_token": "[UNK]",
  "sep_token": "[SEP]",
  "pad_token": "[PAD]",
  "cls_token": "[CLS]",
  "mask_token": "[MASK]",
  "additional_special_tokens": ["[NAME]", "[RELIGION]"]
}

Requirements

torch==1.4.0
transformers==2.11.0
attrdict==2.0.1

Hyperparameters

You can change the parameters from the json files in config directory.

Parameter
Learning rate	5e-5
Warmup proportion	0.1

Max Seq Length	50
Batch size	16

How to Run

For taxonomy, choose original, group or ekman

$ python3 run_goemotions.py --taxonomy {$TAXONOMY}

$ python3 run_goemotions.py --taxonomy original
$ python3 run_goemotions.py --taxonomy group
$ python3 run_goemotions.py --taxonomy ekman

Results

Best Result of Macro F1

Macro F1 (%)	Dev	Test
original	50.16	50.30
group	69.41	70.06
ekman	62.59	62.38

Pipeline

Inference for multi-label classification was made possible by creating a new MultiLabelPipeline class.
Already uploaded finetuned model on Huggingface S3.

1. Original GoEmotions Taxonomy

from transformers import BertTokenizer
from model import BertForMultiLabelClassification
from multilabel_pipeline import MultiLabelPipeline
from pprint import pprint

tokenizer = BertTokenizer.from_pretrained("monologg/bert-base-cased-goemotions-original")
model = BertForMultiLabelClassification.from_pretrained("monologg/bert-base-cased-goemotions-original")

goemotions = MultiLabelPipeline(
    model=model,
    tokenizer=tokenizer,
    threshold=0.3
)

texts = [
    "Hey that's a thought! Maybe we need [NAME] to be the celebrity vaccine endorsement!",
    "it’s happened before?! love my hometown of beautiful new ken 😂😂",
    "I love you, brother.",
    "Troll, bro. They know they're saying stupid shit. The motherfucker does nothing but stink up libertarian subs talking shit",
]

pprint(goemotions(texts))

# Output
 [{'labels': ['neutral'], 'scores': [0.9750906]},
 {'labels': ['curiosity', 'love'], 'scores': [0.9694574, 0.9227462]},
 {'labels': ['love'], 'scores': [0.993483]},
 {'labels': ['anger'], 'scores': [0.99225825]}]

2. Group Taxonomy

from transformers import BertTokenizer
from model import BertForMultiLabelClassification
from multilabel_pipeline import MultiLabelPipeline
from pprint import pprint

tokenizer = BertTokenizer.from_pretrained("monologg/bert-base-cased-goemotions-group")
model = BertForMultiLabelClassification.from_pretrained("monologg/bert-base-cased-goemotions-group")

goemotions = MultiLabelPipeline(
    model=model,
    tokenizer=tokenizer,
    threshold=0.3
)

texts = [
    "Hey that's a thought! Maybe we need [NAME] to be the celebrity vaccine endorsement!",
    "it’s happened before?! love my hometown of beautiful new ken 😂😂",
    "I love you, brother.",
    "Troll, bro. They know they're saying stupid shit. The motherfucker does nothing but stink up libertarian subs talking shit",
]

pprint(goemotions(texts))

# Output
[{'labels': ['positive'], 'scores': [0.9989434]},
 {'labels': ['ambiguous', 'positive'], 'scores': [0.99801123, 0.99845874]},
 {'labels': ['positive'], 'scores': [0.99930394]},
 {'labels': ['negative'], 'scores': [0.9984231]}]

3. Ekman Taxonomy

from transformers import BertTokenizer
from model import BertForMultiLabelClassification
from multilabel_pipeline import MultiLabelPipeline
from pprint import pprint

tokenizer = BertTokenizer.from_pretrained("monologg/bert-base-cased-goemotions-ekman")
model = BertForMultiLabelClassification.from_pretrained("monologg/bert-base-cased-goemotions-ekman")

goemotions = MultiLabelPipeline(
    model=model,
    tokenizer=tokenizer,
    threshold=0.3
)

texts = [
    "Hey that's a thought! Maybe we need [NAME] to be the celebrity vaccine endorsement!",
    "it’s happened before?! love my hometown of beautiful new ken 😂😂",
    "I love you, brother.",
    "Troll, bro. They know they're saying stupid shit. The motherfucker does nothing but stink up libertarian subs talking shit",
]

pprint(goemotions(texts))

# Output
 [{'labels': ['joy', 'neutral'], 'scores': [0.30459446, 0.9217335]},
 {'labels': ['joy', 'surprise'], 'scores': [0.9981395, 0.99863845]},
 {'labels': ['joy'], 'scores': [0.99910116]},
 {'labels': ['anger'], 'scores': [0.9984291]}]
