delphin.mrs¶
This module contains classes and methods related to Minimal Recursion
Semantics [MRS]. In addition to MRS, there are the related formalisms
Robust Minimal Recursion Semantics [RMRS], Elementary Dependency
Structures [EDS], and Dependency Minimal Recursion Semantics [DMRS].
As a convenience, *MRS refers to the collection of MRS and related
formalisms (so “MRS” then refers to the original formalism), and
PyDelphin accordingly defines Xmrs
as the
common subclass for the various formalisms.
Users will interact mostly with Xmrs
objects, but will not often instantiate them directly. Instead, they
are created by serializing one of the various formats (such as
delphin.mrs.simplemrs
, delphin.mrs.mrx
, or
:mod;`delphin.mrs.dmrx`). No matter what serialization format (or
formalism) is used to load a *MRS structure, it will be stored the
same way in memory, so any queries or actions taken on these structures
will use the same methods.
