Thus, the dataset presents several 'double fields' of which one collects the data as it appears in the document and other the data in its standardized version. This, in order to allow the scientific community to criticize our interpretation and to enrich it with new elements in the future. These resources become the basis for creating the knowledge graph for our data and the visualization application described below.</hi>
