TRMA_supporting_data_release

This deposit provides supporting data for “Human-Centered Adaptive Conversational Recommendation with Temporal Retrieval-Augmented Memory.”It includes Amazon-Time-Dial, a dataset of 2,000 de-identified synthetic conversational recommendation dialogues with fixed train/validation/test splits (1,200/300/500), variable dialogue lengths from six to ten turns, provenance metadata, a data dictionary, and source and reuse documentation. The dataset was derived from the Amazon Reviews 2023 Movies & TV source release; the upstream raw source files are not redistributed.The deposit also includes machine-readable CSV exports of the numerical values reported in the manuscript tables and figures, including recommendation accuracy, factuality and hallucination comparisons, retrieval-strategy comparisons, dialogue-efficiency results, human-study measures and aggregate outcomes, and ablation results.Individual-level questionnaire responses and interaction records from the 40-participant study are not included because of participant privacy and consent restrictions. Aggregate numerical data supporting the reported human-study tables and figures are included.
