To implement a BERT-based text summarizer in TensorFlow, you can use Hugging Face's Transformers library with TensorFlow. Here is the code you can refer to:

In the above, we are using approaches like:

  • Load Pre-trained BERT:

    • Use Hugging Face's TFBertForSequenceClassification for initial setup.
    • Fine-tune a BERT model on a summarization dataset (e.g., CNN/DailyMail).
  • Preprocess Input Text:

    • Tokenize the text using BertTokenizer.
    • Ensure the input is truncated or padded to the model's maximum sequence length.
  • Generate Summary:

    • Feed the input to the model.
    • Decode the output logits into human-readable text.
  • Fine-tune for Summarization:

    • Use a summarization-specific dataset for fine-tuning BERT or switch to TFBartForConditionalGeneration for better results, as BERT itself is not directly optimized for summarization.
Hence, this code serves as a starting point, but for high-quality summarization, consider fine-tuning the model or using a pre-trained summarization model like Facebook/bart-large-cnn or t5-small.
