MemU is designed to manage structured, long-term memory for agents.
This issue focuses on enhancing the category files generated by the Memory Category Layer of MemU, via:

• Enriching category files with references to memory items that provide supporting evidence or supplementary information to specific points in the category files, similar to the citations or hyperlinks in Wikipedia.
• Leveraging these references to facilitate the retrieval in subsequent layers when the information in the retrieved category files is judged to be insufficient.

Requirements

Your pull request should include:

• Enhanced memorization workflow
  • Automatic reference integration of the hyperlinks or indices to memory items that provide evidence or supplementary information.
  • Prompt revision to support the creation of the reference between summarized content and memory items.
• Enhanced retrieval workflow
  • Utilization of these hyperlinks or indices in the subsequent retrieval in the Memory Item Layer (when necessary).
• Compatibility guarantee
  • No side-effects in the presentation of category files
  • In textual retrieval result, these references should be folded as citations to supplementary data

Review Criteria

Submissions will be evaluated based on:

• Correctness of references
  • References should be valid and meaningfully established.
  • Unlike the essential category-item links already implemented in MemU, these references must be anchored to specific sentences in category files where supporting evidence or supplementary information is required.
• Reference-aware retrieval
  • Retrievals in subsequent layers should reasonably take these references into account.
• Readability of retrieved category files
  • The inclusion and utilization of references should not degrade the clarity and overall structure of the retrieved category files.
