Abstract
In this paper, we present a formal linguistic system for the annotation of proforms which has been developed and implemented in the framework of the tectogrammatical layer of the Prague Dependency Treebank 2.0. The main motivation of our approach is the following: if there is a semantically relevant regularity within a certain subset of pro-forms, then it is more useful – at least from the viewpoint of treebank users interested in natural language semantics, in conversions into logical forms etc. – if such information is available in the treebank in an explicit, machine-tractable form.
In this case, the semantic features originally present in the word form (given its context) are extracted and stored as values of inner parameters of tectogrammatical nodes corresponding to the given word form.
