ABSTRACT
Due to the technical words employed, which are primarily recognized by medical specialists, information retrieval in the medical area is sometimes described as sophisticated. Because of this, users frequently have trouble coming up with queries utilizing these medical phrases. However, this problem may be readily fixed by an information retrieval system that finds the pertinent terms that fit the user's query and automatically creates a ranking document using these keywords. To enhance the IR performance, the Automatic Query expansion method is applied by appending additional query terms for the medical domain. We propose a novel fuzzy‐based Grasshopper Optimization Algorithm (GOA) based on automatic query expansion. This work is mainly focused on filtering the most relevant augmented query by utilizing the synchronization score of IR evidence like normalized term frequency, inverse document frequency, and normalization of document length. The main aim of this work is to identify the medical terms that appropriately match the user's queries. The GOA algorithm ranks the terms based on relevance and then identifies the terms with the maximum synchronization value. The documents formed using the optimal expanded query are classified into three types, namely totally relevant, moderately relevant, and marginally relevant. Besides, the comparison of the proposed work is carried out for different performance metrics like Mean‐Average Precision, F‐measure, Precision‐recall, and Precision rank are evaluated and analyzed by using TREC‐COVID, TREC Genomics 2007, and MEDLARs medical datasets for the proposed and some of the state‐of‐art works. For a total of 60 queries, the proposed model offers an F1‐Score of 0.964, 0.959, and 0.968 for the MEDLARS, TREC Genomics, and TREC COVID19 datasets, respectively. The E1‐score and Mean Reciprocal Rate (MRR) of the proposed model is 0.8 and 0.9 when evaluated using the TREC COVID19 dataset. Performance analyses show that the proposed approach outperforms the other automatic keyword expansion approaches in the medical domain.

ABSTRACT
Most pandemic burdens, for instance, genuine extreme respiratory conditions, pandemic flu start in animals, are invited on utilizing contaminations and are pushed to ascend by strategies for ecological, direct, or budgetary changes. In this, how mechanical and self-proceeding with structures and quick wearable enhancement and help social protection transport and the restorative administrations gathering of workers for the term of the COVID-19 pandemic are presented. For instance, mechanized and telerobotic structures altogether limit the danger of powerful issue transmission to forefront human administrations people through creation it possible to triage, survey, screen, and treat casualties from a protected division great deal occurrences of the recognize the clinical, planning, and science systems get together to resource the restorative administration’s structure, therapeutic administrations workers, and society all through the propelled disaster are presented. This section centers around computational strategies and real factors, artificial Intelligence (AI) and Big Data can help in dealing with the gigantic, unprecedented proportion of records got from open health surveillance, consistent plague flare-ups watching, vogue right now tossing/deciding, common condition briefing and invigorating from authoritative establishments and animals, and prosperity office utilization of information. © 2021 Scrivener Publishing LLC.
