لامبی متن کا سنبھال
فائلوں کے ساتھ کام کرتے وقت، جیسے کہ پی ڈی ایف وغیرہ، آپ کو ان متن سے واسطہ ہونا ممکن ہے کہ آپ کے لینگویج ماڈل کے سنبھال کے ونڈو سے زیادہ متن کا سامنا ہو۔ اس متن کو پروسیس کرنے کے لئے، مندرجہ ذیل استراتیجیے دھیان میں رکھیں:
- LLM تبدیل کریں ایک ایسا LLM منتخب کریں جو زیادہ ونڈو کو سپورٹ کرتا ہے۔
- بروٹ فورس دستاویز کو ٹکڑوں میں تقسیم کریں، اور ہر ٹکڑے سے مواد حاصل کریں۔
- RAG دستاویز کو ٹکڑوں میں تقسیم کریں، ٹکڑوں کو انڈیکس کریں، اور صرف ان ٹکڑوں سے مواد حاصل کریں جو "اہم" نظر آتے ہیں۔
یاد رہے کہ یہ استراتیجیوں میں مختلف تبادلے ہیں اور بہترین استراتیجیے کا انتخاب ممکن ہے جو آپ کے ڈیزائن کردہ اطلاق پر منحصر ہو!
نتائج میل کریں
ہم چنکس سے ڈیٹا استخراج کرنے کے بعد، ہم ان استخراجات کو ایک ساتھ ملانا چاہیں گے۔

Welcome! How can I assist you today?
RAG کی بنیاد پر آمادہ روایت
اہم شکایات کو حل کرنے کا ایک سادہ طریقہ یہ ہے کہ متن کو ٹکڑوں میں تقسیم کریں، لیکن ہر ٹکڑے سے معلومات حاصل کرنے کی بجائے صرف اہم ترین ٹکڑوں پر توجہ دیں۔
احتیاط
اہم ٹکڑے کو پہچاننا مشکل ہوسکتا ہے۔
مثال کے طور پر، جیسے ہم یہاں استعمال کررھے ہیں car مضمون میں زیادہ تر مضمون کو کلیدی ترقیاتی معلومات شامل ہوتی ہیں۔ لہذا RAG کا استعمال کرتے ہوئے، ہم ممکن ہے بہت سی اہم معلومات کو رد کر رہے ہوں۔
ہم آپکو تجویز دیتے ہیں کہ اپنے استعمال کے حالات کے ساتھ تجربہ کریں اور یہ تعین کریں کہ یہ دستیابی کا طریقہ کار کام کرتا ہے یا نہیں۔
یہاں ایک سادہ مثال ہے جو FAISS ویکٹر اسٹور پر انحصار کرتی ہے۔
from langchain_community.vectorstores import FAISS
from langchain_core.documents import Document
from langchain_core.runnables import RunnableLambda
from langchain_openai import OpenAIEmbeddings
from langchain_text_splitters import CharacterTextSplitter
texts = text_splitter.split_text(document.page_content)
vectorstore = FAISS.from_texts(texts, embedding=OpenAIEmbeddings())
retriever = vectorstore.as_retriever(
search_kwargs={"k": 1}
) # صرف پہلے دستاویز سے حاصل کریں
اس مقام میں RAG ایکسٹریکٹر صرف اوپر دستاویز پر غور کر رہا ہے۔
rag_extractor = {
"text": retriever | (lambda docs: docs[0].page_content) # بالائی دستاویز کی مواد حاصل کریں
} | extractor
results = rag_extractor.invoke("Key developments associated with cars")

year=1925 description='Morris had 41% of total British car production, dominating the market.' evidence='in 1925, Morris had 41 per cent of total British car production.'
year=1925 description='Citroën, Renault, and Peugeot produced 550,000 cars in France, dominating the market.' evidence="Citroën did the same in France, coming to cars in 1919; between them and other cheap cars in reply such as Renault's 10CV and Peugeot's 5CV, they produced 550,000 cars in 1925."

عام مسائل
مختلف تراکیب کے اپنے فوائد اور نقصانات ہوتے ہیں جو لاگت، رفتار، اور درستگی سے متعلق ہوتے ہیں۔
ان مسائل کا خیال رکھیں:
- مواد کو ٹکڑوں میں تقسیم کرنے سے معلومات کو حاصل کرنے میں LLM ناکام رہ سکتا ہے اگر معلومات کئی ٹکڑوں پر پھیلا ہے۔
- بڑے حصے کی اورلپ سے مایوس ہونے کا خدشہ ہے کہ وہی معلومات دو بار حاصل ہوجائے، لہذا جدال کے لیے تیار رہیں!
- LLMs میں معلومات کو بنا سکتے ہیں۔ اگر آپ ایک بڑے متن میں ایک ہی حقیقت کی تلاش کر رہے ہیں اور بھیم فورس ترکیب کا استعمال کررہے ہیں تو آپ کو زیادہ تشکیل شدہ معلومات حاصل ہوجائیں گی۔
