Rosni Vasu (University of Zurich) - SciHyp: A Fine-grained Dataset Describing Hypotheses and Their Components from Scientific Articles

Neurocognition, Language and Visual Processing (NLVP) series


Event details

Abstract: Scientific discovery involves understanding and structuring hypotheses, a challenging task due to the complexity of scientific texts. This talk presents SciHyp, a novel dataset containing RDF descriptions of 689 hypothesis sentences from 479 computer science articles. These hypotheses include relation-finding and comparative types. The dataset was created using a multi-step annotation pipeline with expert annotation, Language Models (LMs) like BERT and Sci-BERT, and crowd-based refinement. Our pipeline effectively identified non-hypothesis sentences with a 96.1% consensus rate between the LMs and crowd annotations, demonstrating its effectiveness in identifying relevant sentences that contain hypotheses. We also used GPT-4 to extract hypothesis components. SciHyp aims to benefit the scientific community by providing a structured dataset for model training and evaluation. The talk concludes with a glimpse into an ongoing project making use of the SciHyp pipeline for scientific hypotheses generation.

Bio: Rosni Vasu is an Informatics PhD student at the University of Zurich, where she is advised by Prof. Abraham Bernstein. Her research focuses on human-machine collaboration for scientific text understanding and reasoning. She is particularly interested in how humans and machines can jointly contribute to the tasks of scientific hypothesis detection, generation, and ranking.
