A sentiment analysis of tweets and social network leaders 2023 Access copy available to the general public Unrestricted In accordance with the cognitive orientation contemplated in the resolution of complex problems posed in public decision-making using decision support systems and social networks, this work studies the possibility of identifying the state of mind of society through the state of mind of network leaders. Using sentiment and emotion analysis as research techniques and Twitter as a representative social network, the study corpus considers tweets and retweets in Spanish about COVID-19 in the period from February 27, 2020 to December 31, 2021. As cognitive orientation claims, the proposed techniques will allow us to extract the arguments that support the different positions and decisions from the analysis of the tweets issued exclusively by social leaders. In the case study considered, the COVID-19 vaccination process in Spain, the reduction in the number of tweets′ authors (more than 8,000) to the network leaders (just 8) was greater than 99 %; and the subsequent reduction in the number of associated tweets was greater than 88 % from the 18,193 tweets in society to the 2,145 tweets of the eight social leaders. The impressive degree of information compression achieved may be useful to establish new directions of social mood analysis applied to healthcare and business management. info:eu-repo/grantAgreement/ES/DGA-FEDER/S35-23R info:eu-repo/grantAgreement/ES/DGA/LMP 35-21 info:eu-repo/grantAgreement/ES/MICINN/PID2022-139863OB-I00 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 3.4 2023 MULTIDISCIPLINARY SCIENCES 28 / 134 = 0.209 2023 Q1 T1 0.617 2023 Multidisciplinary 2023 Q1 4.5 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Aguarón, Juan Universidad de Zaragoza (orcid)0000-0003-3138-7597 Moreno-Jiménez, José María Universidad de Zaragoza (orcid)0000-0002-5037-6976 Turón, Alberto Universidad de Zaragoza (orcid)0000-0002-8807-8958 4014 623 Universidad de Zaragoza Dpto.
