Introduction ‐ Scenario

• Scenario in the context of tourism and travelling where the content is

“El Viajero” platform

• 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)

Introduction – Provenance

• Users want to know where does the information come from, who has manipulated it and which references have been used.

P i f i i i i l d i h h b• Provenance information is critical to determine whether a resource can be trusted or not.

• “Provenance of a resource is a record that describes entities and processesProvenance 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.
