DEEP-PolyU/LinearRAG

• highreadme#1

  Reposition the README's opening statement to highlight the problem LinearRAG solves for existing GraphRAG

  Why:

  CURRENT

  A relation-free graph construction method for efficient GraphRAG. It eliminates LLM token costs during graph construction, making GraphRAG faster and more efficient than ever.

  COPY-PASTE FIX

  ## 💡 Why LinearRAG? (Comparison to Existing GraphRAG)
  Traditional GraphRAG systems often struggle with high LLM token costs and computational overhead during graph construction, especially for large-scale corpora. Unlike general RAG frameworks or graph databases, LinearRAG offers a unique relation-free approach that directly tackles these inefficiencies, providing a more scalable and cost-effective solution for complex reasoning tasks.
