1 like967 views
The document discusses 'El Viajero', a provenance-aware linked data application designed for trip management and organization in the tourism sector. It emphasizes the importance of provenance information in determining the trustworthiness of aggregated content from various sources such as travel guides and blogs. The architecture and future enhancements of the application are outlined, including dynamic data insertion and links to external datasets.

Introduction ‐ Scenario “El Viajero” platform • Scenario in the context of tourism and travelling where the content is Scenario in the context of tourism and travelling, where the content is aggregated from different platforms, such as “Suplemento El País”, ”Guías Aguilar”, “Canal Viajar” o “Prisa Digital”. • Heterogeneous content (images, travel guides, posts, videos, news) with different sources and from people with different profiles (journalists, bloggers and normal users) 4
- 5. Introduction – Provenance • Users want to know where does the information come from, who has manipulated it and which references have been used. •PProvenance information is critical to determine whether a resource can be i f i i ii l d i h h b trusted or not. • “Provenance of a resource is a record that describes entities and processes Provenance of a resource is a record that describes entities and processes involved in producing and delivering or otherwise influencing that resource” (W3C Provenance Incubator Group). • Open Provenance Model. • Popular provenance model centered in the evolution of the resources. • Close to PIL (Provenance Interchange Language), currently being developed in the W3C. 5
