The invention relates to a method (1) for the automated creation of a data set (4), which characterizes a technical drawing (2) having symbols (S1...s6) and lines (l1...l8) connecting the symbols (s1...s6), from the drawing (2), comprising the following steps performed in a computer system: a) scanning the technical drawing (2), b) identifying the symbols (s1...s6) in the technical drawing (2) and storing nodes representing the respective symbols (s1...s6) in the data set (4), c) identifying lines (l1...l8) each connecting at least two symbols (s1...s6) in the technical drawing (2) and storing connections representing the respective lines (l1...l8) in the data set (4), wherein at least two end points are associated with each connection and one of the nodes that represent the symbols (s1...s6) connected by the particular line (l1...l8) is associated with each end point, d) providing a symbol library (8) having a plurality of symbol types (st1...st7) and symbol data (10) associated with each symbol type (st1...st7), e) associating exactly one symbol type (st1...st7) from the symbol library (8) with each node at least on the basis of the symbol data (10) and storing the associated symbol types (st1...st7) for the respective nodes in the data set (4), should make it possible to automatically extract semantic information and relationships from vectorized data of a technical drawing such that said semantic information and relationships are available for further processing. For this purpose, step d) comprises storing a number of connection points (a1...a3) having connection-point data (12) associated with each connection point (a1...a3) for a number of the symbol types (st1...st7) in the symbol library (8), and step e) comprises associating exactly one connection point (a1...a3) with each of a number of end points at least on the basis of the connection-point data (12) and storing the respective associated connection points (a1...a3) for the end points in the data set (4). |
