{"doi":"10.1145/3676288.3676289","title":"Knowledge Graph Enhancement for Improved Natural Language Health Question Answering using Large Language Models","abstract":"In this paper we present a method for enhancing Question Answering (QA) systems by iteratively improving Knowledge Graphs (KGs) with a focus on maintaining monotonicity in the enhancement process. We introduce a mathematical framework employing functions τ and ϕ, where τ transforms text T into a KG K, and ϕ generates an answer from T for a given question. We propose that augmenting K with domain-specific information, denoted as ΔK, leads to a more accurate approximation of the expected answer, adhering to the principle that each enhancement either maintains or improves answer quality. This concept is formalized as ϕ− 1(ϕ(T) ∪ ΔK) yielding better results than ϕ− 1(ϕ(T)). The paper elaborates on this process with practical examples, demonstrating how KG enhancements, under the constraints of monotonicity, lead to successive improvements in the Question Answering (QA) system.","journal":null,"year":2024,"id":488879,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":2,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9561,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2024-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1167799,"name":"Joel Oduro-Afriyie","orcid":"0000-0001-8912-4568","position":1,"is_corresponding":false},{"id":982400,"name":"Hasan M.
