In the ever-evolving field of natural language processing (NLP), text classification is a crucial task that enables machines to understand and categorize text data correctly. This blog will guide you through how to utilize a fine-tuned Turkish text classification model, significantly enhancing your capabilities in processing Turkish language tasks.

Understanding the Turkish Text Classification Model

The Turkish Text Classification model is based on the renowned BERT architecture, specifically designed for capturing the nuances of the Turkish language. We have seven categories for classification:

• LABEL_0: dünya (world)
• LABEL_1: ekonomi (economy)
• LABEL_2: kultur (culture)
• LABEL_3: saglik (health)
• LABEL_4: siyaset (politics)
• LABEL_5: spor (sports)
• LABEL_6: teknoloji (technology)

Getting Started with Turkish Text Classification

To begin using the Turkish text classification model, follow these simple steps:

Step 1: Install Required Libraries

Start by installing the transformers library, which provides the tools you need for modeling:

pip install transformers

Step 2: Import Necessary Libraries

Use the following code to import the essential libraries:

from transformers import pipeline, AutoModelForTokenClassification, AutoTokenizer, AutoModelForSequenceClassification

Step 3: Load the Model and Tokenizer

Next, load the tokenizer and model. The time taken will depend on your internet connection:

tokenizer = AutoTokenizer.from_pretrained('savasybert-turkish-text-classification')
model = AutoModelForSequenceClassification.from_pretrained('savasybert-turkish-text-classification')

Step 4: Create a Pipeline

With the model and tokenizer ready, you can create a pipeline for sentiment analysis:

nlp = pipeline('sentiment-analysis', model=model, tokenizer=tokenizer)

Step 5: Analyze Text

Now you’re ready to analyze text. Simply apply the model as shown below:

result = nlp("bla bla")
label = result[0]['label']
score = result[0]['score']
code_to_label[label]

This will yield the label and corresponding score, classifying the input text into one of the defined categories.

Data Loading and Model Training

After analyzing text, you might want to understand how to prepare your data and train your own model.

Loading Data for Training

Use pandas to read in your Turkish text classification dataset:

import pandas as pd
df = pd.read_csv('7allV03.csv')
df.columns = ['labels', 'text']
df.labels = pd.Categorical(df.labels)

Setting Up the Classification Model

Next, use the Simple Transformers library to set up your classification model:

from simpletransformers.classification import ClassificationModel
import torch
import sklearn

model_args = {
    'use_early_stopping': True,
    'early_stopping_delta': 0.01,
    'early_stopping_metric': 'mcc',
    'early_stopping_metric_minimize': False,
    'early_stopping_patience': 5,
    'evaluate_during_training_steps': 1000,
    'fp16': False,
    'num_train_epochs': 3
}

model = ClassificationModel('bert', 'dbmdz/bert-base-turkish-cased', use_cuda=torch.cuda.is_available(), args=model_args, num_labels=7)
model.train_model(train_df, acc=sklearn.metrics.accuracy_score)

In this code, we configure various parameters to optimize model training and accuracy.

Using the Model

Troubleshooting

If you encounter issues during installation or model execution, consider the following troubleshooting tips:

• Ensure that your Python environment is set up correctly with all dependencies installed.
• Check your internet connection if models take too long to load.
• Refer to the official documentation of the libraries for specific error messages.
