Fragments GREMAS

As the next syntactic device let us consider three-position descriptors, each position of which provides information of a particular kind. These pieces of information are firmly associated in one term, which creates an especially close connection between them. Such terms have proved successful in the fragment code GREMAS for chemical structures and also for the documentation of patent literature in the fields of plant protection and agriculture (see Figure 5).

The main disadvantage until now was that the GREMAS fragments had to be evaluated manually in the case of Markush structures of any complexity. This is a...
