Through different projects, the iArtHis_Lab (www.iarthislab.es) research group has been analyzing the mechanisms for the production and distribution of cultural information on the Internet since 2015. Furthermore, this research group has considered the possibilities of reusing this information in the form of structured data to generate new knowledge and value through computational processing techniques. The interest of this research is derived from two main motivations. First, there is the need to examine and unveil the informational gaps that the digital society is producing in the cultural field. Secondly, there is the need to evaluate the potential connections between such inequalities and the development of the so-called creative economy.
