OntoTouTra: Tourist Traceability Ontology Based on Big Data Analytics. Appl. Sci. 2021, 11, 11061. https://doi.org/10.3390/app1122110612076-3417https://hdl.handle.net/10016/34173Tourist traceability is the analysis of the set of actions, procedures, and technical measures that allows us to identify and record the space–time causality of the tourist’s touring, from the beginning to the end of the chain of the tourist product. Besides, the traceability of tourists has implications for infrastructure, transport, products, marketing, the commercial viability of the industry, and the management of the destination’s social, environmental, and cultural impact. To this end, a tourist traceability system requires a knowledge base for processing elements, such as functions, objects, events, and logical connectors among them. A knowledge base provides us with information on the preparation, planning, and implementation or operation stages. In this regard, unifying tourism terminology in a traceability system is a challenge because we need a central repository that promotes standards for tourists and suppliers in forming a formal body of knowledge representation. Some studies are related to the construction of ontologies in tourism, but none focus on tourist traceability systems. For the above, we propose OntoTouTra, an ontology that uses formal specifications to represent knowledge of tourist traceability systems. This paper outlines the development of the OntoTouTra ontology and how we gathered and processed data from ubiquitous computing using Big Data analysis techniqueseng© MDPI, 2021Atribución 3.0 Españatourist traceabilityontologybig dataanalyticsubiquitous computingresearch articleInformáticahttps://doi.org/10.3390/app112211061open access12238Applied Sciences (Switzerland)11AR/0000029110
