GIS or CAD systems are able to handle precise coordinates (x,y,z). Historical texts with descriptions of rooms or buildings do not use them, but other concepts, such as "Object A is on the opposite wall of object B", "Object C has a height of 2m.", "Object D is in the same room as object E", etc. To compute all of these concepts, a space describing ontology (e.g. RCC8-calculus extended) will be created. After that, for every text-to-3d process
- Identify expressions in the text, that describe spatial objects (e.g. altar, window) and spatial relations (e.g. behind, inside).
- Transform these expressions into the space describing ontology.
- Transform the out coming semantic graph into a 3D-model.
