A preeminent problem affecting urban planning is the appropriate choice of location to host a particular activity (either commercial or common welfare service) or the correct use of an existing building or empty space. In this paper, we propose an approach to address these challenges availed with machine learning techniques. The proposed system combines, fuses, and merges various types of data from different sources, encodes them using a novel semantic model that can capture and utilize both low-level geometric information and higher level semantic information and subsequently feeds them to the random forests classifier, as well as other supervised machine learning models for comparisons. Our experimental evaluation on multiple real-world data sets comparing the performance of several classifiers (including Feedforward Neural Networks, Support Vector Machines, Bag of Decision Trees, k-Nearest Neighbors and Na\u00efve Bayes), indicated the superiority of Random Forests in terms of the examined performance metrics (Accuracy, Specificity, Precision, Recall, F-measure and G-mean).<\/jats:p>","DOI":"10.3390\/s19102266","type":"journal-article","created":{"date-parts":[[2019,5,16]],"date-time":"2019-05-16T11:21:22Z","timestamp":1558005682000},"page":"2266","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Using Random Forests on Real-World City Data for Urban Planning in a Visual Semantic Decision Support System"],"prefix":"10.3390","volume":"19","author":[{"given":"Nikolaos","family":"Sideris","sequence":"first","affiliation":[{"name":"Department of Informatics and Computer Engineering, University of West Attica, 12243 Athens, Greece"},{"name":"XLIM, University of Limoges, 87060 Limoges CEDEX, France"}]},{"given":"Georgios","family":"Bardis","sequence":"additional","affiliation":[{"name":"Department of Informatics and Computer Engineering, University of West Attica, 12243 Athens, Greece"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0632-9769","authenticated-orcid":false,"given":"Athanasios","family":"Voulodimos","sequence":"additional","affiliation":[{"name":"Department of Informatics and Computer Engineering, University of West Attica, 12243 Athens, Greece"}]},{"given":"Georgios","family":"Miaoulis","sequence":"additional","affiliation":[{"name":"Department of Informatics and Computer Engineering, University of West Attica, 12243 Athens, Greece"}]},{"given":"Djamchid","family":"Ghazanfarpour","sequence":"additional","affiliation":[{"name":"XLIM, University of Limoges, 87060 Limoges CEDEX, France"}]}],"member":"1968","published-online":{"date-parts":[[2019,5,16]]},"reference":[{"key":"ref_1","unstructured":"(2019, February 25).
