City-Zen – Citizens’ platform for cultural heritage
The way tourists organize their travels is evolving day after day. While in the past, information was more obtained by the support of tour operators, nowadays this is mainly obtained through the Internet. Among many options, on the Internet it is possible to get information about interesting things a place has and to make reservations. This new touristic paradigm brings attractive opportunities such as saving money and discovering unexploited information proposed by tourists that already have visited targeted places. But, it comes with a major shortcoming. Information on the Internet can be overwhelming and it can lead to a lot of time spent on planning a travel. Moreover, the Internet contains outdated and incorrect information which can cause incorrect travel planning. These issues can become even more preponderant when dealing with niche domains, such as cultural heritage, where the information is not pervasive.
The goal of the project is to valorise the existing cultural heritage through a citizen centric design platform. In order to provide this novel spatio-temporal multimedia platform, City-Zen needs to rely on a database which contains the integrated information coming from various sources such as linked open data, user-provided data (e.g., ratings, photos), geo-spatial data, temporal data and multimedia data (heterogeneous data integration, linking mapping and cleaning). Its core is a database with a spatio-temporal data model with a sophisticated index structure that supports the different query types identified above (knowledge based querying and browsing). It relies also on a set of data visualization approaches, browsing and visualization (personalized data and information visualization).
