Abstract

Open-domain Multi-Document Summarization (ODMDS) is a critical tool for condensing vast arrays of documents into coherent, concise summaries. With a more inter-related document set, there does not necessarily exist a correct answer for the retrieval, making it hard to measure the retrieving performance. We propose a rule-based method to process query-based document summarization datasets into ODMDS datasets. Based on this method, we introduce a novel dataset, ODSum, a sophisticated case with its document index interdependent and often interrelated. We tackle ODMDS with the \textit{retrieve-then-summarize} method, and the performance of a list of retrievers and summarizers is investigated. Through extensive experiments, we identify variances in evaluation metrics and provide insights into their reliability. We also found that LLMs suffer great performance loss from retrieving errors. We further experimented methods to improve the performance as well as investigate their robustness against imperfect retrieval. We will release our data and code at https://github.com/yale-nlp/ODSum.

46. Creative Factors and Psychotherapeutic Insight: Effects of Novelty and Appropriateness

Author

Liu, Ruixuan, Yu, Fei, Zhang, Jianxin, Zhang, Wencai, and Luo, Jing

Abstract

Novelty and appropriateness have long been considered as the two fundamental elements of creativity; however, whether these two can separately affect creativity or its related processes remains unclear. In the present study, the authors focused on psychotherapeutic insight to identify the different effects of novelty and appropriateness. Three experiments were conducted (total N = 452) using a micro-counseling dialogue (MCD) paradigm, which can induce stable and differential insights by providing different types of solutions to mental distress problems (Experiment 1) and negative descriptions (Experiment 2). Further, in Experiment 3, the authors improved the study by employing a group of high school students with test anxiety (assessed using the Test Anxiety Inventory), which was more ecological. Across the three experiments, higher insightfulness and pleasantness were induced by high novelty (experiments 1 and 2) and appropriateness (experiments 1 to 3). In Experiment 3, the effect of test anxiety was found, wherein the low-test anxiety group generated higher insightfulness compared to the high-test anxiety group, and this effect was stronger in the inappropriateness condition. The results provide evidence that novelty and appropriateness are key factors in inducing psychotherapeutic insightfulness.
