GRASUM at BioLaySumm Task 1: Background Knowledge Grounding for Readable, Relevant, and Factual Biomedical Lay Summaries
Domenic Rosati · 2023
Communication of scientific findings to the public is important for keeping non-experts informed of developments such as life-saving medical treatments.However, generating readable lay summaries from scientific documents is challenging, and currently, these summaries suffer from critical factual errors.One popular intervention for improving factuality is using additional external knowledge to provide factual grounding.However, it is unclear how these grounding sources should be retrieved, selected, or integrated, and how supplementary grounding documents might affect the readability or relevance of the generated summaries.We develop a simple method for selecting grounding sources and integrating them with source documents.We then use the Bio-LaySumm summarization dataset to evaluate the effects of different grounding sources on summary quality.We found that grounding source documents improves the relevance and readability of lay summaries but does not improve factuality of lay summaries.This continues to be true in zero-shot summarization settings where we hypothesized that grounding might be even more important for factual lay summaries 1 .1 https://github.com/domenicrosati/improving-lay-factuality-with-retreivalLay Summary: [Messenger RNAs carry the instructions necessary to synthesize proteins that do work for the cell]background In this work , we surveyed mRNA ends from 10 , 000 genes in immune cells from genetically distinct human individuals.Abstracts: Virtually all messenger RNAs (mRNAs) in eukaryotes are cleaved and polyadenylated at their 3 ends.UMLS: RNA is unique among biological macromolecules in that it can encode genetic information.Wiki Simple: Messenger RNA carries a genetic message from the DNA to the protein making machinery of the cell.
