In this regard, our proposed Ontology-Based Sentiment Analysis provides two novel approaches: First, the emotion extraction on tweets related to COVID-19 is carried out by a well-formed taxonomy that comprises possible emotional concepts with fine-grained properties and polarized values. Second, the potential entities present in the tweet can be analyzed for semantic associativity. The extraction of emotions can be performed in two cases: (i) words directly associated with the emotional concepts present in the taxonomy and (ii) words indirectly present in the emotional concepts. Though the latter case is very challenging in processing the tweets to find the hidden patterns and extract the meaningful facts associated with it, our proposed work is able to extract and detect almost 81% of true positives and considerably able to detect the false negatives. Finally, the proposed approach's superior performance is witnessed from its comparison with other peer-level approaches.<\/jats:p>","DOI":"10.3389\/fpubh.2021.798905","type":"journal-article","created":{"date-parts":[[2021,12,6]],"date-time":"2021-12-06T05:00:53Z","timestamp":1638766853000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":14,"title":["Ontology-Enabled Emotional Sentiment Analysis on COVID-19 Pandemic-Related Twitter Streams"],"prefix":"10.3389","volume":"9","author":[{"given":"Senthil Kumar","family":"Narayanasamy","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kathiravan","family":"Srinivasan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Saeed","family":"Mian Qaisar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chuan-Yu","family":"Chang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2021,12,6]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"3901","DOI":"10.1007\/s10462-019-09782-9","article-title":"Automatic ontology construction from text: a review from shallow to deep learning trend","volume":"53","author":"Al-Aswadi","year":"2020","journal-title":"Artific Intell Rev."},{"key":"B2","doi-asserted-by":"publisher","first-page":"5462.","DOI":"10.3390\/app9245462","article-title":"Emotion ai-driven sentiment analysis: a survey, future research directions, open issues.","volume":"9","author":"Chakriswaran","year":"","journal-title":"Appl.
