Turkish Text Classification

This model is a fine-tune model of https://github.com/stefan-it/turkish-bert by using text classification data where there are 7 categories as follows

code_to_label={
 'LABEL_0': 'dunya ',
 'LABEL_1': 'ekonomi ',
 'LABEL_2': 'kultur ',
 'LABEL_3': 'saglik ',
 'LABEL_4': 'siyaset ',
 'LABEL_5': 'spor ',
 'LABEL_6': 'teknoloji '}
 

Data

The following Turkish benchmark dataset is used for fine-tuning

https://www.kaggle.com/savasy/ttc4900

Quick Start

Bewgin with installing transformers as follows

pip install transformers

# Code:
# import libraries
from transformers import pipeline, AutoModelForTokenClassification, AutoTokenizer, AutoModelForSequenceClassification
tokenizer= AutoTokenizer.from_pretrained("savasy/bert-turkish-text-classification")

# build and load model, it take time depending on your internet connection
model= AutoModelForSequenceClassification.from_pretrained("savasy/bert-turkish-text-classification")

# make pipeline
nlp=pipeline("sentiment-analysis", model=model, tokenizer=tokenizer)

# apply model
nlp("bla bla")
# [{'label': 'LABEL_2', 'score': 0.4753005802631378}]

code_to_label={
 'LABEL_0': 'dunya ',
 'LABEL_1': 'ekonomi ',
 'LABEL_2': 'kultur ',
 'LABEL_3': 'saglik ',
 'LABEL_4': 'siyaset ',
 'LABEL_5': 'spor ',
 'LABEL_6': 'teknoloji '}
 
code_to_label[nlp("bla bla")[0]['label']]
# > 'kultur '
