Furthermore, researchers have discovered that relying solely on the overall sentiment derived from the textual content is inadequate. Consequently, sentiment analysis was developed to extract nuanced expressions from textual information. One of the challenges in this field is effectively extracting emotional elements using multi-label data that covers various aspects. This article presents a novel approach called the Ensemble of DenseNet based on Aquila Optimizer (EDAO). EDAO is specifically designed to enhance the precision and diversity of multi-label learners. Unlike traditional multi-label methods, EDAO strongly emphasizes improving model diversity and accuracy in multi-label scenarios. To evaluate the effectiveness of our approach, we conducted experiments on seven distinct datasets, including emotions, hotels, movies, proteins, automobiles, medical, news, and birds. Our initial strategy involves establishing a preprocessing mechanism to obtain precise and refined data. Subsequently, we used the Vader tool with Bag of Words (BoW) for feature extraction. In the third stage, we created word associations using the word2vec method. The improved data were also used to train and test the DenseNet model, which was fine-tuned using the Aquila Optimizer (AO). On the news, emotion, auto, bird, movie, hotel, protein, and medical datasets, utilizing the aspect-based multi-labeling technique, we achieved accuracy rates of 95%, 97%, and 96%, respectively, with DenseNet-AO. Our proposed model demonstrates that EDAO outperforms other standard methods across various multi-label datasets with different dimensions. The implemented strategy has been rigorously validated through experimental results, showcasing its effectiveness compared to existing benchmark approaches.<\/jats:p>","DOI":"10.3390\/a16120548","type":"journal-article","created":{"date-parts":[[2023,11,28]],"date-time":"2023-11-28T11:43:16Z","timestamp":1701171796000},"page":"548","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["An Efficient Optimized DenseNet Model for Aspect-Based Multi-Label Classification"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1153-5401","authenticated-orcid":false,"given":"Nasir","family":"Ayub","sequence":"first","affiliation":[{"name":"Department of Creative Technologies, Air University Islamabad, Islamabad 44000, Pakistan"}]},{"family":"Tayyaba","sequence":"additional","affiliation":[{"name":"Department of Computing, Riphah International University, Faisalabad 38000, Pakistan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1523-1330","authenticated-orcid":false,"given":"Saddam","family":"Hussain","sequence":"additional","affiliation":[{"name":"School of Digital Science, Universiti Brunei Darussalam, Jalan Tungku Link, Gadong BE1410, Brunei"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5406-0389","authenticated-orcid":false,"given":"Syed Sajid","family":"Ullah","sequence":"additional","affiliation":[{"name":"Department of Information and Communication Technology, University of Agder (UiA), N-4898 Grimstad, Norway"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5045-7485","authenticated-orcid":false,"given":"Jawaid","family":"Iqbal","sequence":"additional","affiliation":[{"name":"Faculty of Computing, Riphah International University, Islamabad 44000, Pakistan"}]}],"member":"1968","published-online":{"date-parts":[[2023,11,28]]},"reference":[{"key":"ref_1","first-page":"1","article-title":"Money Laundering and Abuse of the Financial System","volume":"5","author":"Singh","year":"2023","journal-title":"Indian JL & Legal Rsch."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"107073","DOI":"10.1016\/j.knosys.2021.107073","article-title":"Multiple-element joint detection for aspect-based sentiment analysis","volume":"223","author":"Wu","year":"2021","journal-title":"Knowl.-Based Syst."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"76","DOI":"10.1016\/j.ins.2017.10.017","article-title":"Imbalanced enterprise credit evaluation with DTE-SBD: Decision tree ensemble based on SMOTE and bagging with differentiated sampling rates","volume":"425","author":"Sun","year":"2018","journal-title":"Inf.
