The paper introduces a repeat‑run evaluation framework for AI agents that process large unstructured datasets, focusing on theme churn and volume disagreement as key metrics. Experiments on three customer‑feedback tasks across eight frontier models show that a taxonomy‑grounded agent (TGA) dramatically reduces theme churn by 86–88% and eliminates volume disagreement compared to raw generation and hierarchical decomposition. The framework is applicable beyond customer feedback, to any recurring synthesis of unstructured corpora such as financial reports, legal documents, incident records, and scientific literature.
Corpus2Skill is a retrieval architecture that transforms an enterprise knowledge base into a hierarchical skill directory, enabling an LLM agent to navigate from high-level summaries to specific documents and backtrack when necessary. On an enterprise customer‑support benchmark, it outperforms single‑shot dense, hybrid, hierarchical‑retrieval, and agentic RAG baselines in answer quality and grounding, with a moderate cost tradeoff. An eleven‑dataset study shows that corpus navigation excels on single‑domain corpora with a recoverable topical taxonomy but is less effective on open‑domain factoid pools or homogeneous‑tabular corpora, providing a design guideline for knowledge‑grounded systems.
The paper introduces a lifecycle framework for LLM-as-a-Judge systems used to evaluate recommendation explanations at Netflix. It outlines four phases—Birth, Training, Deployment, and Monitoring—detailing how each stage addresses specific technical and operational challenges. The authors report that after five weeks of A/B testing, judge-aligned explanations increased novel content viewing and successful browse-to-play sessions without quality takedowns.
