Experimental evaluation of ontology-based HIV/AIDS frequently asked question retrieval system

Abstract

This study presents the results of experimental evaluations of an ontology-based frequently asked question retrieval system in the domain of HIV and AIDS. The main purpose of the system is to provide answers to questions on HIV/AIDS using ontology. To evaluate the effectiveness of the frequently asked question retrieval system, we conducted two experiments. The first experiment focused on the evaluation of the quality of the ontology we developed using the OQuaRE evaluation framework which is based on software quality metrics and metrics designed for ontology quality evaluation. The second experiment focused on evaluating the effectiveness of the ontology in retrieving relevant answers. For this we used an open-source information retrieval platform, Terrier, with retrieval models BM25 and PL2. For the measurement of performance, we used the measures mean average precision, mean reciprocal rank, and precision at 5. The results suggest that frequently asked question retrieval with ontology is more effective than frequently asked question retrieval without ontology in the domain of HIV/AIDS.

Developing a pneumonia diagnosis ontology from multiple knowledge sources

“…We used Text2Onto 34,35 tool to build the corpus from the CPGs. The CQs were used to identify terms in the corpus that are relevant to pneumonia diagnosis.…”

“…These CPGs came from Cochrane Collaboration, 25 National Institute for Health and Care Excellence (NICE), 26 Infectious Diseases Society of America (IDSA), 27 European Society of Clinical Microbiology and Infectious Diseases (ESCMID), 28 Australian Society for Infectious Diseases (ASID), 29 Canadian Respiratory Guidelines (CTS), 30 Pulmonary and Critical Care Medicine (PulmCCM), 31 American Thoracic Society (ATS), 32 and British Thoracic Society (BTS). 33 We used Text2Onto 34,35 tool to build the corpus from the CPGs. The CQs were used to identify terms in the corpus that are relevant to pneumonia diagnosis.…”

“…Different approaches to ontology evaluation were discussed in the literature. 35,[54][55][56] Also, several authors have proposed automated tools to evaluate ontologies. 57,58 However, most of these tools are either prototypes or under development, with only OOPS!…”

Social Media, Grindr, and PrEP: Sexual Health Literacy for Men Who Have Sex with Men in the Internet Age

“…The development of novel information technology tools in order to support online HIV consumer health is another research path holding great potential. Current research in this area includes: the development of an ontology-based FAQ query system for HIV/AIDS information [39], future versions of which could potentially be incorporated into GSN app sexual health information sections; continued research into social media data mining and monitoring to help make informed decisions and strategies concerning online HIV information materials [20,27,28]; and the creation of automated text summaries from health social media posts [40].…”

An Ontological Approach for Dental Extraction Decision Making and Knowledge Dissemination – A Pilot Study for Dental Extraction Forceps

“…Modelling ontology is a time-taking process (Walisadeera et al, 2013b) and hence requires appropriate tools (Ayalew et al, 2018). Further, constructing a domain ontology from the beginning is a complicated task.…”
