The ensemble approach has achieved remarkable results in sentiment classification tasks due to its superior performance. The primary reason behind the success of ensemble methods is the enhanced diversity of the base classifiers. The boosting method employs a sequential ensemble structure to construct diverse data while also utilizing erroneous data by assigning higher weights to misclassified samples in the next training round. However, this method tends to use a sequential ensemble structure, resulting in a long computation time. Conversely, the voting method employs a concurrent ensemble structure to reduce computation time but neglects the utilization of erroneous data. To address this issue, this study combines the advantages of voting and boosting methods and proposes a new two-stage voting boosting (2SVB) concurrent ensemble learning method for social network sentiment classification. This novel method not only establishes a concurrent ensemble framework to decrease computation time but also optimizes the utilization of erroneous data and enhances ensemble performance. To optimize the utilization of erroneous data, a two-stage training approach is implemented. Stage-1 training is performed on the datasets by employing a 3-fold cross-segmentation approach. Stage-2 training is carried out on datasets that have been augmented with the erroneous data predicted by stage 1. To augment the diversity of base classifiers, the training stage employs five pre-trained deep learning (PDL) models with heterogeneous pre-training frameworks as base classifiers. To reduce the computation time, a two-stage concurrent ensemble framework was established. The experimental results demonstrate that the proposed method achieves an F1 score of 0.8942 on the coronavirus tweet sentiment dataset, surpassing other comparable ensemble methods.<\/jats:p>","DOI":"10.3390\/e25040555","type":"journal-article","created":{"date-parts":[[2023,3,24]],"date-time":"2023-03-24T03:16:46Z","timestamp":1679627806000},"page":"555","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["A Two-Stage Voting-Boosting Technique for Ensemble Learning in Social Network Sentiment Classification"],"prefix":"10.3390","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4619-3114","authenticated-orcid":false,"given":"Su","family":"Cui","sequence":"first","affiliation":[{"name":"Department of Electronic Information, Engineering University of Chinese People\u2019s Armed Police Force, Xi\u2019an 710086, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2116-5408","authenticated-orcid":false,"given":"Yiliang","family":"Han","sequence":"additional","affiliation":[{"name":"Department of Electronic Information, Engineering University of Chinese People\u2019s Armed Police Force, Xi\u2019an 710086, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yifei","family":"Duan","sequence":"additional","affiliation":[{"name":"Department of Computer and Information Technology, University of Pennsylvania, Philadelphia, PA 19019, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Electronic Information, Engineering University of Chinese People\u2019s Armed Police Force, Xi\u2019an 710086, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuaishuai","family":"Zhu","sequence":"additional","affiliation":[{"name":"Department of Electronic Information, Engineering University of Chinese People\u2019s Armed Police Force, Xi\u2019an 710086, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chaoyue","family":"Song","sequence":"additional","affiliation":[{"name":"Department of Electronic Information, Engineering University of Chinese People\u2019s Armed Police Force, Xi\u2019an 710086, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1120","DOI":"10.1007\/s11390-015-1587-1","article-title":"Microblog sentiment analysis with emoticon space model","volume":"30","author":"Jiang","year":"2015","journal-title":"J.
