What is this?

At this repo, I'm releasing the training script and a full working inference example for my model mys/bert-base-turkish-cased-nli-mean-faq-mnr published on HuggingFace. Please note that the training code at finetune_tf.py is a simplified version of the original, which is intended for educational purposes and not optimized for anything. However, it contains an implementation of the Multiple Negatives Symmetric Ranking loss, and you can use it in your own work. Additionally, I cleaned and filtered the Turkish subset of the clips/mqa dataset, as it contains lots of mis-encoded texts. You can download this cleaned dataset here.

Model

This is a finetuned version of mys/bert-base-turkish-cased-nli-mean for FAQ retrieval, which is itself a finetuned version of dbmdz/bert-base-turkish-cased for NLI. It maps questions & answers to 768 dimensional vectors to be used for FAQ-style chatbots and answer retrieval in question-answering pipelines. It was trained on the Turkish subset of clips/mqa dataset after some cleaning/ filtering and with a Multiple Negatives Symmetric Ranking loss. Before finetuning, I added two special tokens to the tokenizer (i.e., for questions and for answers) and resized the model embeddings, so you need to prepend the relevant tokens to the sequences before feeding them into the model. Please have a look at my accompanying repo to see how it was finetuned and how it can be used in inference. The following code snippet is an excerpt from the inference at the repo.

Usage

see inference.py for a full working example.

" + q for q in questions] answers = ["" + a for a in answers] def answer_faq(model, tokenizer, questions, answers, return_similarities=False): q_len = len(questions) tokens = tokenizer(questions + answers, padding=True, return_tensors='tf') embs = model(**tokens)[0] attention_masks = tf.cast(tokens['attention_mask'], tf.float32) sample_length = tf.reduce_sum(attention_masks, axis=-1, keepdims=True) masked_embs = embs * tf.expand_dims(attention_masks, axis=-1) masked_embs = tf.reduce_sum(masked_embs, axis=1) / tf.cast(sample_length, tf.float32) a = tf.math.l2_normalize(masked_embs[:q_len, :], axis=1) b = tf.math.l2_normalize(masked_embs[q_len:, :], axis=1) similarities = tf.matmul(a, b, transpose_b=True) scores = tf.nn.softmax(similarities) results = list(zip(answers, scores.numpy().squeeze().tolist())) sorted_results = sorted(results, key=lambda x: x[1], reverse=True) sorted_results = [{"answer": answer.replace("", ""), "score": f"{score:.4f}"} for answer, score in sorted_results] return sorted_results for question in questions: results = answer_faq(model, tokenizer, [question], answers) print(question.replace("", "")) print(results) print("---------------------") ">
questions = [
    "Merhaba",
    "Nasılsın?",
    "Bireysel araç kiralama yapıyor musunuz?",
    "Kurumsal araç kiralama yapıyor musunuz?"
]

answers = [
    "Merhaba, size nasıl yardımcı olabilirim?",
    "İyiyim, teşekkür ederim. Size nasıl yardımcı olabilirim?",
    "Hayır, sadece Kurumsal Araç Kiralama operasyonları gerçekleştiriyoruz. Size başka nasıl yardımcı olabilirim?",
    "Evet, kurumsal araç kiralama hizmetleri sağlıyoruz. Size nasıl yardımcı olabilirim?"
]


questions = ["" + q for q in questions]
answers = ["" + a for a in answers]


def answer_faq(model, tokenizer, questions, answers, return_similarities=False):
    q_len = len(questions)
    tokens = tokenizer(questions + answers, padding=True, return_tensors='tf')
    embs = model(**tokens)[0]

    attention_masks = tf.cast(tokens['attention_mask'], tf.float32)
    sample_length = tf.reduce_sum(attention_masks, axis=-1, keepdims=True)
    masked_embs = embs * tf.expand_dims(attention_masks, axis=-1)
    masked_embs = tf.reduce_sum(masked_embs, axis=1) / tf.cast(sample_length, tf.float32)
    a = tf.math.l2_normalize(masked_embs[:q_len, :], axis=1)
    b = tf.math.l2_normalize(masked_embs[q_len:, :], axis=1)

    similarities = tf.matmul(a, b, transpose_b=True)
        
    scores = tf.nn.softmax(similarities)
    results = list(zip(answers, scores.numpy().squeeze().tolist()))
    sorted_results = sorted(results, key=lambda x: x[1], reverse=True)
    sorted_results = [{"answer": answer.replace("", ""), "score": f"{score:.4f}"} for answer, score in sorted_results]
    return sorted_results


for question in questions:
    results = answer_faq(model, tokenizer, [question], answers)
    print(question.replace("", ""))
    print(results)
    print("---------------------")

And the output is:
