Catena Operations for Unified Dependency Analysis
Kiril Simov, Petya Osenova · Bulgarian Portal for Open Science · 2015
The notion of catena was introduced originally to represent the syntactic structure of multiword expressions with idiosyncratic semantics and non-constituent structure. Later on, several other phenomena (such as ellipsis, verbal complexes, etc.) were formalized as catenae. This naturally led to the suggestion that a catena can be considered a basic unit of syntax. In this paper we present a formalization of catenae and the main operations over them for modelling the combinatorial potential of units in dependency grammar.
