Researchers are now wondering whether in the new era of data-driven geography it is possible to give a concrete shape to the concept of rhizome, by analyzing big data describing movement of people traced through social media. This paper is a first attempt to give a concrete shape to the concept of rhizome, by interpreting it as a problem of \u201citemset mining\u201d, which is a well-known data mining technique. This technique was originally developed for market-basket analysis. We studied how the application of this technique, if supported by adequate visualization strategies, can provide geographers with a concrete shape for rhizomes, suitable for further studies. To validate the ideas, we chose the case study of tourists visiting a city: the rhizome can be conceived as the set of places visited by many tourists, and the common transfers made by tourists in the area of the city. Itemsets extracted from a real-life data set were used to study the effectiveness of both a topographic representation and a topological representation to visualize rhizomes. In this paper, we study how three different interpretations are actually able to give a concrete and visual shape to the concept of rhizome. The results that we present and discuss in this paper open further investigations on the problem.<\/jats:p>","DOI":"10.3390\/informatics8010001","type":"journal-article","created":{"date-parts":[[2020,12,24]],"date-time":"2020-12-24T22:56:45Z","timestamp":1608850605000},"page":"1","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["From Data to Rhizomes: Applying a Geographical Concept to Understand the Mobility of Tourists from Geo-Located Tweets"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3440-0670","authenticated-orcid":false,"given":"Federica","family":"Burini","sequence":"first","affiliation":[{"name":"Department of Foreign Languages, Literatures and Cultures, University of Bergamo, Via Salvecchio 19, 24129 Bergamo, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1899-0180","authenticated-orcid":false,"given":"Nicola","family":"Cortesi","sequence":"additional","affiliation":[{"name":"Consortium for Technology Transfer C2T, Corso di Porta Vittoria, 28, 20122 Milano, Italy"},{"name":"Department of Management, Information and Production Engineering, University of Bergamo, Viale Marconi 5, 24044 Dalmine, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9228-560X","authenticated-orcid":false,"given":"Giuseppe","family":"Psaila","sequence":"additional","affiliation":[{"name":"Department of Management, Information and Production Engineering, University of Bergamo, Viale Marconi 5, 24044 Dalmine, Italy"}]}],"member":"1968","published-online":{"date-parts":[[2020,12,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1250","DOI":"10.15252\/embr.201541001","article-title":"Could Big Data be the end of theory in science?","volume":"16","author":"Mazzocchi","year":"2015","journal-title":"EMBO Rep."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"449","DOI":"10.1007\/s10708-014-9602-6","article-title":"Data-driven geography","volume":"80","author":"Miller","year":"2015","journal-title":"GeoJournal"},{"key":"ref_3","unstructured":"Deleuze, G., Guattari, F., P\u00e9rez, J.V., and Larraceleta, U.
