🚀 Quick Start

Installation 

pip install sentence-transformers

Basic Usage 

from sentence_transformers import SentenceTransformer

# Load model
model = SentenceTransformer('tasal9/Multilingual-ZamAI-Embeddings')

# Encode sentences
sentences = [
    "د افغانستان ښکلی ملک دی",  # Pashto
    "Afghanistan is a beautiful country",  # English
    "افغانستان یک کشور زیبا است"  # Dari/Persian
]

embeddings = model.encode(sentences)
print(f"Embeddings shape: {embeddings.shape}")  # (3, 384)

# Compute similarity
from sentence_transformers import util

similarities = util.cos_sim(embeddings[0], embeddings[1:])
print(f"Pashto-English similarity: {similarities[0][0]:.4f}")
print(f"Pashto-Dari similarity: {similarities[0][1]:.4f}")

Semantic Search 

from sentence_transformers import SentenceTransformer, util

model = SentenceTransformer('tasal9/Multilingual-ZamAI-Embeddings')

# Documents to search (mixed languages)
documents = [
    "د افغانستان تاریخ",
    "Afghan culture and traditions",
    "فرهنگ افغانستان",
    "Machine learning basics",
    "د ماشین زده کړه",
    "Programming in Python"
]

# Search query
query = "Afghan history and culture"

# Encode
doc_embeddings = model.encode(documents)
query_embedding = model.encode([query])

# Find most similar
similarities = util.cos_sim(query_embedding, doc_embeddings)[0]
top_results = similarities.argsort(descending=True)[:3]

print("Top 3 most similar documents:")
for idx in top_results:
    print(f"  {documents[idx]} (score: {similarities[idx]:.4f})")

Document Clustering 

from sentence_transformers import SentenceTransformer
from sklearn.cluster import KMeans
import numpy as np

model = SentenceTransformer('tasal9/Multilingual-ZamAI-Embeddings')

# Documents in multiple languages
documents = [
    "Afghanistan news",
    "خبرهای افغانستان",
    "د افغانستان خبرونه",
    "Technology updates",
    "د ټیکنالوژۍ خبرونه",
    "Sports results",
    "د سپورت پایلې"
]

# Create embeddings
embeddings = model.encode(documents)

# Cluster
kmeans = KMeans(n_clusters=3, random_state=42)
clusters = kmeans.fit_predict(embeddings)

# Show clusters
for i, (doc, cluster) in enumerate(zip(documents, clusters)):
    print(f"Cluster {cluster}: {doc}")

Question Answering / FAQ Search 

from sentence_transformers import SentenceTransformer, util

model = SentenceTransformer('tasal9/Multilingual-ZamAI-Embeddings')

# FAQ database (multilingual)
faqs = [
    "What is the capital of Afghanistan?",
    "د افغانستان پلازمینه څه ده؟",
    "How to apply for a visa?",
    "ویزه څنګه ترلاسه کړو؟",
    "Business hours and contact information",
    "د کار ساعتونه او د اړیکې معلومات"
]

answers = [
    "The capital of Afghanistan is Kabul.",
    "د افغانستان پلازمینه کابل دی.",
    "Visit our visa application page online.",
    "زموږ د ویزې غوښتنلیک پاڼه کتل کړئ.",
    "We are open 9 AM to 5 PM, Monday to Friday.",
    "موږ د دوشنبې نه تر جمعې پورې له ۹ سهار نه تر ۵ ماسپښین کار کوو."
]

# User query
query = "What are the office hours?"

# Encode and search
faq_embeddings = model.encode(faqs)
query_embedding = model.encode([query])

# Find best match
similarities = util.cos_sim(query_embedding, faq_embeddings)[0]
best_match = similarities.argmax()

print(f"Query: {query}")
print(f"Best match: {faqs[best_match]}")
print(f"Answer: {answers[best_match]}")
print(f"Similarity: {similarities[best_match]:.4f}")

  • Less optimal for: Very long documents, specialized technical jargon
  • Language balance: Better performance on high-resource languages
  • Domain: General-purpose, may need fine-tuning for specific domains
  • Cultural nuance: Some idiomatic expressions may not transfer perfectly
