arXiv – CS AI|Anka Chandrahas Tummepalli, Preethu Rose Anish||1 views
🤖AI Summary

Researchers developed LexChronos, an AI framework that extracts structured event timelines from Indian Supreme Court judgments using a dual-agent architecture. The system achieved 0.8751 F1 score on synthetic data and showed 75% preference over unstructured approaches in legal text summarization tasks.

Key Takeaways
  • LexChronos uses a dual-agent AI architecture with LoRA-instruct-tuned extraction and feedback agents to process legal documents.
  • The framework addresses the lack of Indian legal datasets by creating a synthetic corpus of 2000 samples using DeepSeek-R1 and GPT-4.
  • The system achieved a BERT-based F1 score of 0.8751 against synthetic ground truth data.
  • GPT-4 preferred structured timelines over unstructured baselines in 75% of legal text summarization cases.
  • The framework enables future legal AI applications including precedent mapping, argument synthesis, and predictive judgment modeling.
