The MRS and RMRS representation languages are designed for compositional semantics. These pages are primarily intended to cover aspects of the implemented MRS and RMRS support in the LKB and other DELPHIN tools, as well as the use of RMRS with shallow processors.
These pages are very much under development: additions would be welcome.
RMRS predicates are decorated with the start and end points of the input text they correspond to (RmrsSpan). This makes it easier to link RMRS to other annotations, including RMRS from different sources.
Design: Some discussion of topics related to (R)MRS.
RmrsPos: RMRS defines a list of coarse POS distinctions.
RmrsParaphrasing: A discussion of how to paraphrase using (R)MRS.
RmrsModel: A discussion of the Model Theory of (R)MRS.
RmrsDistributional: A discussion of distributional techniques.
SEMI-I: The SEMantic-Interface.
VPM: Variable Property Mapping (between the TFS and MRS universes).
EDS: Variable-Free Elementary Dependency Structures.
DMRS: Dependencies which may be interconverted with MRS.
And some Frequently Asked Questions.
For computing equivalence (i.e. isomorphism) of two MRSs (note, not accounting for RMRS), please see MrsIsomorphism.
