We are starting a research program into an automation of formal modelling. The first project is developed together with ABBYY - the leading linguistic company. The project studies possibilities to build a Gellish-like formal model of a natural language technical document, for further transformation into an ISO 15926 compliant data model with TabLan.15926 engine. This presentation shows preliminary comparisons between syntactic and semantic structures parsed by ABBYY Compreno and manually prepared formal text models.
