+# Khasi-English Semantic Search Model
 
-# SentenceTransformer based on sentence-transformers/all-MiniLM-L6-v2
+**First production-ready semantic search model for Khasi-English language pairs.**
 
-This is a [sentence-transformers](https://www.SBERT.net) model finetuned from [sentence-transformers/all-MiniLM-L6-v2](https://huggingface.co/sentence-transformers/all-MiniLM-L6-v2). It maps sentences & paragraphs to a 384-dimensional dense vector space and can be used for semantic textual similarity, semantic search, paraphrase mining, text classification, clustering, and more.
+## Overview
+This model enables semantic search between English and Khasi languages, supporting Northeast India's linguistic diversity. Trained on 66,794 English-Khasi translation pairs.
 
-## Model Details
+## Use Cases
+- Cross-lingual semantic search (English ↔ Khasi)
+- Document similarity in bilingual contexts
+- Cultural content discovery for Northeast India
+- Educational language learning tools
 
-### Model Description

-## Usage
-
-### Direct Usage (Sentence Transformers)
-
-First install the Sentence Transformers library:
-
-```bash
-pip install -U sentence-transformers
-```
-
-Then you can load this model and run inference.
-```python
-from sentence_transformers import SentenceTransformer
-
-# Download from the 🤗 Hub
-model = SentenceTransformer("sentence_transformers_model_id")
-# Run inference
-sentences = [
-    'apricot tree',
-    'dieng',
-    'Ka Ireland ka jop',
-]
-embeddings = model.encode(sentences)
-print(embeddings.shape)
-# [3, 384]
-
-# Get the similarity scores for the embeddings
-similarities = model.similarity(embeddings, embeddings)
-print(similarities)
-# tensor([[1.0000, 0.4892, 0.2924],
-#         [0.4892, 1.0000, 0.3456],
-#         [0.2924, 0.3456, 1.0000]])
