Both decision makers and tourists can take advantage from these data, as demonstrated by previous works, with institutional actors foreseeing an increase in the use of this data to substitute other time-consuming and expensive approaches. However, managing multiple sources built with different goals and structures is not straightforward, so specific design choices must be made when assembling this kind of information. Graph databases represent an ideal way to combine multiple-source data but, to be successful, strategies accounting for inconsistencies and format differences have to be defined to support coherent analysis. Also, the continuously changing nature of crowd-sourced data makes it difficult, for the research community, to compare technological approaches to the different tasks that are linked to cultural heritage, from recommendation to management. To support the research effort in this direction, we describe the data ingestion and enrichment procedure we followed to organise knowledge coming from three different sources, namely Wikidata, Wikipedia, and Flickr, into a single, application-oriented, resource organised as a graph database. We present the potential use of this resource to perform multiple source analyses targeting the specific case of cultural tourism on a nationwide scale, and we propose its use as a shared benchmark for technological applications designed to support optimal management of cultural resources.<\/jats:p>","DOI":"10.1145\/3465741","type":"journal-article","created":{"date-parts":[[2021,7,16]],"date-time":"2021-07-16T06:06:48Z","timestamp":1626415608000},"page":"1-27","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":23,"title":["Multiple-source Data Collection and Processing into a Graph Database Supporting Cultural Heritage Applications"],"prefix":"10.1145","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3379-1756","authenticated-orcid":false,"given":"Antonio","family":"Origlia","sequence":"first","affiliation":[{"name":"Department of Electrical Engineering and Information Technology, University of Naples Federico II"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Silvia","family":"Rossi","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering and Information Technology, University of Naples Federico II"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sergio Di","family":"Martino","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering and Information Technology, University of Naples Federico II"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francesco","family":"Cutugno","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering and Information Technology, University of Naples Federico II &amp; URBAN\/ECO Research Centre, University of Naples Federico II"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Laura","family":"Chiacchio","sequence":"additional","affiliation":[{"name":"URBAN\/ECO Research Centre, University of Naples Federico II"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"320","published-online":{"date-parts":[[2021,7,16]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0150466"},{"key":"e_1_2_1_2_1","volume-title":"Digital Cultural Heritage","author":"Aliprantis John","unstructured":"John Aliprantis , Eirini Kalatha , Markos Konstantakis , Kostas Michalakis , and George Caridakis . 2018.
