About

This repository stores the data crawling and processing code for the GreekReddit dataset, as well as the training and evaluation code for the proposed models. The proposed models were trained and evaluated on GreekReddit. The dataset and best-performing models are hosted on HuggingFace.

Installation

pip install requirements.txt

Example Code

from transformers import AutoModelForSequenceClassification, AutoTokenizer, pipeline

model_name = 'IMISLab/Greek-Reddit-BERT'
model = AutoModelForSequenceClassification.from_pretrained(model_name)
tokenizer = AutoTokenizer.from_pretrained(model_name) 

topic_classifier = pipeline(
    'text-classification',
    device = 'cpu',
    model = model,
    tokenizer = tokenizer,
    truncation = True,
    max_length = 512
)
    
text = 'Άλλες οικονομίες, όπως η Κίνα, προσπαθούν να διατηρούν την αξία του νομίσματος τους χαμηλά ώστε να καταστήσουν τις εξαγωγές τους πιο ελκυστικές στο εξωτερικό. Γιατί όμως θεωρούμε πως η πτωτική πορεία της Τουρκικής λίρας είναι η ""αχίλλειος πτέρνα"" της Τουρκίας;'
output = topic_classifier(text)
print(output[0]['label'])
