Domain-Adapted Retrieval for In-Context Annotation of Pedagogical Dialogue Acts

Jinsook Lee, Kirk Vanacore, Zhuqian Zhou +2

Automated annotation of pedagogical dialogue is a high-stakes task where LLMs often fail without sufficient domain grounding. We present a domain-adapted RAG pipeline for tutoring…

Codebook-Injected Dialogue Segmentation for Multi-Utterance Constructs Annotation: LLM-Assisted and Gold-Label-Free Evaluation

Jinsook Lee, Kirk Vanacore, Zhuqian Zhou +3

Dialogue Act (DA) annotation typically treats communicative or pedagogical intent as localized to individual utterances or turns. This leads annotators to agree on the underlying a…

AI Annotation Orchestration: Evaluating LLM verifiers to Improve the Quality of LLM Annotations in Learning Analytics

Bakhtawar Ahtisham, Kirk Vanacore, Jinsook Lee +3

Large Language Models (LLMs) are increasingly used to annotate learning interactions, yet concerns about reliability limit their utility. We test whether verification-oriented orch…
