HintMiner: Automatic Question Hints Mining From Q&A Web Posts with Language Model via Self-Supervised Learning

HintMiner is an automatic tool that mines question hints from web Q&A posts using a language‑model‑based MiningNet. It retrieves many Q&A posts, extracts hints via a transformer‑based encoder‑decoder with copying mechanisms, and is trained with a self‑supervised objective on large online data. Evaluated on 60,000 Stack Overflow questions, HintMiner achieves an average BLEU score of 36.17% and ROUGE‑2 of 36.29%.

Beyond-RAG: Question Identification and Answer Generation in Real-Time Conversations

The paper presents a decision‑support system that enhances retrieval‑augmented generation (RAG) for customer contact centers by first identifying customer questions in real time. If a query matches a frequently asked question (FAQ), the system retrieves the answer directly from the FAQ database; otherwise it generates an answer via RAG, delivering responses to agents within two seconds. The approach reduces manual query formulation, lowers average handling times, and cuts operational costs, and it includes an automated workflow that uses LLMs to extract FAQs from historical transcripts when none are predefined.

CONTRA: Discovering and Qualifying Behavior-Changing Questions for Selective Clarification in LLM Code Generation

CONTRA is a training‑free method that discovers and qualifies behavior‑changing questions for selective clarification in large language model (LLM) code generation. It first generates candidate questions, filters out those unrelated to required behavior or already resolved, then creates programs conditioned on two plausible answers to check for stable behavioral differences on shared inputs. Experiments on ClarifyCodeBench show that CONTRA achieves the highest F1 across four coding agents, outperforming baselines by 13.88 percentage points, and it is also implemented as a Claude Code plugin for practical use.
