Starting from the matrix I S of a given SSyntS, the task is therefore to obtain the matrix I D of the corresponding DSyntS, that is, to identify correspondences between i/j, (i, j) and groups of (i, j) of I S with i /j and (i , j ) of I D ; see (i)-(iii) above.
the task consists in identifying and removing all functional lexemes, and attach correctly the remaining nodes between them.
