摘要:	AI-generated summaries condense lengthy text or video content into short and concise textual summaries, which can facilitate consumer search and reduce information overload. This research designs and evaluates two AI-generated summarization strategies for online videos: information-extractive AI-generated summaries (IAIGS), which present fact-based recaps, and suspense-inducing AI-generated summaries (SAIGS), which withhold key details to spark curiosity. To assess their impact on video consumption, we conducted a randomized field experiment on a video-sharing platform, focusing on two content genres: Science, which primarily addresses users’ instrumental information needs, and Humanities & History, which caters to users’ affective and curiosity-driven interests. We analyzed engagement metrics for 21,533 videos from 1,545 content creators over a six-week period. Our results show that IAIGS consistently reduced video views across both genres, driven by information substitution. In contrast, SAIGS had genre-specific effects: it increased engagement with Humanities & History content by sparking curiosity, but decreased engagement with Science content by obstructing information-seeking. A follow-up online experiment confirmed these patterns and shed light on the underlying mechanisms. Our study highlights the nuanced effects of AI summarization strategies on user engagement across content genres, emphasizing the importance of aligning summary design with user intent and content characteristics. Our findings provide valuable insights for designing AI-generated summaries to enhance user engagement and content consumption.
