INTERPRESS NEWS CLASSIFICATION

Dataset

The dataset downloaded from interpress. This dataset is real world data. Actually there are 273K data but I filtered them and used 108K data for this model. For more information about dataset please visit this link

Model

Model accuracy on train data and validation data is %97. The data split as %80 train and %20 validation. The results as shown as below

news = r"ABD'den Prens Selman'a yaptırım yok Beyaz Saray Sözcüsü Psaki, Muhammed bin Selman'a yaptırım uygulamamanın \"doğru karar\" olduğunu savundu. Psaki, \"Tarihimizde, Demokrat ve Cumhuriyetçi başkanların yönetimlerinde diplomatik ilişki içinde olduğumuz ülkelerin liderlerine yönelik yaptırım getirilmemiştir\" dedi."

Usage for Tensorflow

pip install transformers or pip install transformers==4.3.3

import tensorflow as tf
from transformers import BertTokenizer, TFBertForSequenceClassification
import numpy as np

tokenizer = BertTokenizer.from_pretrained('serdarakyol/interpress-turkish-news-classification')
model = TFBertForSequenceClassification.from_pretrained("serdarakyol/interpress-turkish-news-classification")

inputs = tokenizer(news, return_tensors="tf")
inputs["labels"] = tf.reshape(tf.constant(1), (-1, 1)) # Batch size 1

outputs = model(inputs)
loss = outputs.loss
logits = outputs.logits
pred = np.argmax(logits,axis=1)[0]
labels[pred]
# > World
