40px;\"><em>\u201c\u2026The increasing use of social media and the recent advances in geo-positioning technologies have produced a great amount of geosocial data, consisting of spatial, textual, and social information, to be managed and queried. In this paper, we focus on the issue of query processing by providing a systematic literature review of geosocial data representations, query processing methods, and evaluation approaches published over the last two decades (2000\u20132020). The result of our analysis shows the categories of geosocial queries proposed by the surveyed studies, the query primitives and the kind of access method used to retrieve the result of the queries, the common evaluation metrics and datasets used to evaluate the performance of the query processing methods, and the main open challenges that should be faced in the near future. Due to the ongoing interest in this research topic, the results of this survey are valuable to many researchers and practitioners by gaining an in-depth understanding of the geosocial querying process and its applications and possible future perspectives\u2026\u201d<\/em><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-33 elementor-top-column elementor-element elementor-element-58e26577 elementor-invisible\" data-id=\"58e26577\" data-element_type=\"column\" data-e-type=\"column\" data-settings=\"{&quot;animation&quot;:&quot;fadeInRight&quot;}\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-12ac9344 elementor-mobile-align-center elementor-icon-list--layout-traditional elementor-list-item-link-full_width elementor-widget elementor-widget-icon-list\" data-id=\"12ac9344\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"icon-list.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<ul class=\"elementor-icon-list-items\">\n\t\t\t\t\t\t\t<li class=\"elementor-icon-list-item\">\n\t\t\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/l.cnr.it\/2nnih\" target=\"_blank\">\n\n\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-icon-list-icon\">\n\t\t\t\t\t\t\t<i aria-hidden=\"true\" class=\"fas fa-book-open\"><\/i>\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-icon-list-text\"><b>the article is available for free download<\/span>\n\t\t\t\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t<\/li>\n\t\t\t\t\t\t<\/ul>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-2c164769 elementor-widget elementor-widget-image\" data-id=\"2c164769\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"726\" src=\"https:\/\/www.irpps.cnr.it\/wp-content\/uploads\/2022\/04\/x-sito-News-SENZA-DATA-1024x726.png\" class=\"attachment-large size-large wp-image-30844\" alt=\"\" srcset=\"https:\/\/www.irpps.cnr.it\/wp-content\/uploads\/2022\/04\/x-sito-News-SENZA-DATA-1024x726.png 1024w, https:\/\/www.irpps.cnr.it\/wp-content\/uploads\/2022\/04\/x-sito-News-SENZA-DATA-1080x766.png 1080w, https:\/\/www.irpps.cnr.it\/wp-content\/uploads\/2022\/04\/x-sito-News-SENZA-DATA-300x213.png 300w, https:\/\/www.irpps.cnr.it\/wp-content\/uploads\/2022\/04\/x-sito-News-SENZA-DATA-768x545.png 768w, https:\/\/www.irpps.cnr.it\/wp-content\/uploads\/2022\/04\/x-sito-News-SENZA-DATA-1536x1090.png 1536w, https:\/\/www.irpps.cnr.it\/wp-content\/uploads\/2022\/04\/x-sito-News-SENZA-DATA-18x12.png 18w, https:\/\/www.irpps.cnr.it\/wp-content\/uploads\/2022\/04\/x-sito-News-SENZA-DATA.png 1748w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Query Processing of Geosocial Data in Location-Based Social Networks Arianna D&#8217;Ulizia Patrizia Grifoni Fernando Ferri Arianna D&#8217;Ulizia, Fernando Ferri and Patrizia Grifoni have published an article in the prestigious journal MDPI &#8211;
