How to Generate Sindhi Sentence Level Embedding in Python

What will you learn?

In this tutorial, you will learn how to generate sentence-level embeddings for the Sindhi language using Python. Sentence embeddings are essential numerical representations of sentences that capture their semantic meanings. These embeddings play a vital role in various natural language processing tasks such as text classification, clustering, and similarity matching.

Introduction to the Problem and Solution

Sentence embeddings provide a way to represent sentences numerically while preserving their semantic information. Specifically focusing on the Sindhi language, we aim to generate high-quality sentence embeddings efficiently. To address this challenge, we will utilize pre-trained models from libraries like Hugging Face Transformers. These libraries offer user-friendly interfaces for computing sentence embeddings for multiple languages, including Sindhi. By leveraging these tools, we can avoid the need to train specific models from scratch and quickly obtain meaningful sentence representations.


# Import necessary libraries
from transformers import AutoTokenizer, AutoModel

# Load pre-trained model and tokenizer for Sindhi language
tokenizer = AutoTokenizer.from_pretrained("ai4bharat/indic-bert")
model = AutoModel.from_pretrained("ai4bharat/indic-bert")

# Encode a sample Sindhi sentence to get its embedding
sentence = "Your Sindhi sentence here"
inputs = tokenizer(sentence, return_tensors="pt", padding=True)

with torch.no_grad():
    outputs = model(**inputs)

sentence_embedding = outputs.last_hidden_state.mean(dim=1).squeeze().numpy()

Generating sentence-level embeddings involves converting input sentences into dense vector representations that retain semantic information. The code snippet performs the following steps: – Imports necessary libraries including transformers for utilizing pre-trained models. – Loads a pre-trained model and tokenizer tailored for Indic languages like Sindhi. – Encodes a sample Sindhi sentence using the tokenizer and obtains its corresponding embedding through the model. – Outputs a numerical vector representing the semantics of the input Sindhi sentence.

This process enables us to acquire meaningful representations of sentences in the target language suitable for various downstream NLP tasks efficiently.

    Can I use other pre-trained models for generating embeddings?

    Yes, explore different pre-trained models available on platforms like Hugging Face Model Hub based on your specific requirements and language needs.

    Is it possible to fine-tune these pre-trained models for better performance?

    Fine-tuning pretrained models on domain-specific data can enhance their performance on custom tasks related to your application area or dataset.

    What if my input sentences are in multiple languages?

    Utilize multilingual pretrained models supporting multiple languages simultaneously or switch between specialized models based on your input language requirements.

    Are there any limitations when working with less-resourced languages like Sindhi?

    Working with less-resourced languages may pose challenges related to data availability but leveraging multilingual pretrained models could offer viable solutions in such scenarios.

    Can I visualize these generated embeddings effectively?

    By reducing high-dimensional vectors into 2D space using techniques like PCA or t-SNE, you can visualize similarities between different embedded sentences effectively.

    How do I evaluate the quality of generated embeddings?

    Evaluation metrics such as cosine similarity, Spearman’s rank correlation coefficient or downstream task performance assessment can help quantify embedding quality accurately.

    What preprocessing steps should be considered before generating embeddings?

    Before encoding sentences into numerical vectors, preprocess text by removing stopwords, handling special characters and ensuring uniform casing based on specific use cases.

    Are there any alternatives to transformer-based approaches for generating word/sentence level representation?

    Other alternatives include traditional methods like TF-IDF vectors combined with dimensionality reduction techniques such as SVD or more recent methods like Word2Vec or GloVe depending upon computational resources and desired accuracy levels.


    Generating meaningful sentence-level embeddings is crucial in various natural language processing applications. By following this tutorial and leveraging powerful libraries like Hugging Face Transformers with specialized Indic language support such as Sindhi, you’re equipped with tools capable of efficiently capturing semantic information from textual data. Experimenting with different architectures/models while considering domain-specific requirements would further enhance embedding quality tailored towards diverse NLP tasks.
