Extracted Abstract:
—Today, social media platforms and other online sources, like forums and review sites, offer an abundance of cultural and touristic information that is voluntarily offered by travelers; this information, although helpful for other travelers, is typically fragmented and thus cannot be easily leveraged to ex- ploitable knowledge by scientists and other tourism stakeholders. In this work, we present a novel, integrated system for collecting, managing, analyzing and sharing diverse, multi-faceted cultural heritage/tourism-related data that aims to assist scientists in the cultural heritage domain and tourism stakeholders to gather and synthesize scattered information to exploitable knowledge. The proposed system is tailored to the tourism domain needs, and allows users with minimum effort and zero IT expertise to (i) gather data from both structured and unstructured/semi- structured online sources, (ii) leverage the data to knowledge via appropriate analysis and visualization tools, and (iii) share the collected data and gathered knowledge with other stakeholders via appropriate publish-subscribe mechanisms. The proposed system is entirely open-source, designed upon big data tools and principles for the data store, the analytics production, and the knowledge sharing, and targets both performance and usability.
