Abstract Meaning Representation (AMR)
Abstract Meaning Representations have originally been introduced by Langkilde and Knight (1998)
Existing AMR technology includes tools and libraries for parsing,[5] visualization,[6] and surface generation[7] as well as a considerable number of publicly available data sets. Many of these resources are collected at the AMR homepage[8] at ISI/USC where AMR technology has been originally developed.
Example
Example sentence: The boy wants to go.
(w / want-01
:arg0 (b / boy)
:arg1 (g / go-01
:arg0 b))
As far as predicate semantics are concerned, the role inventory of PropBank is largely based on semantic role annotations in the style of PropBank. Note that in pre-2010 AMR format, `:arg0` would be `:agent`, etc.
Banarescu et al. (2013)[1] claim that this is equivalent to the following logical formula:
In addition, they claim that this representation makes the will of the boy more explicit, highlighting that the intention of the boy is that he himself goes away (because `want-01` is the type of the top-level predicate).
Uniform Meaning Representations
In an extension of the original AMR formalism, Uniform Meaning Representations (UMR) have been proposed.[9] While grounded in AMR, they eliminate specific characteristics of the English language that are featured in AMR, and are thus more easily applicable cross-linguistically.[9]
