Abstract
The evaluation of whole-sentence semantic structures plays an important role in semantic parsing and large-scale semantic structure annotation. However, there is no widely-used metric to evaluate wholesentence semantic structures. In this paper, we present smatch, a metric that calculates the degree of overlap between two semantic feature structures. We give an efficient algorithm to compute the metric and show the results of an inter-annotator agreement study.

Penman: An Open-Source Library and Tool for AMR Graphs

TL;DR: The open-source Python library Penman provides a robust parser, functions for graph inspection and manipulation, and functions for formatting graphs into PENMAN notation, thus extending its utility to non-Python setups.

Sequence-to-sequence Models for Cache Transition Systems

TL;DR: This paper transforms the sequence to graph mapping problem to a word sequence to transition action sequence problem using a special transition system called a cache transition system, and presents a monotonic hard attention model for the transition framework to handle the strictly left-to-right alignment between each transition state and the current buffer input focus.

Core Semantic First: A Top-down Approach for AMR Parsing

TL;DR: A novel scheme for parsing a piece of text into its Abstract Meaning Representation (AMR): Graph Spanning based Parsing (GSP), which achieves the state-of-the-art performance in the sense that no heuristic graph re-categorization is adopted.

An AMR Aligner Tuned by Transition-based Parser

TL;DR: A new rich resource enhanced AMR aligner which produces multiple alignments and a new transition system for AMR parsing along with its oracle parser and a transition-based AMR parser that parses a sentence into its AMR graph directly are proposed.

Bleu: a Method for Automatic Evaluation of Machine Translation

TL;DR: This paper proposed a method of automatic machine translation evaluation that is quick, inexpensive, and language-independent, that correlates highly with human evaluation, and that has little marginal cost per run.

A Study of Translation Edit Rate with Targeted Human Annotation

TL;DR: A new, intuitive measure for evaluating machine translation output that avoids the knowledge intensiveness of more meaning-based approaches, and the labor-intensiveness of human judgments is defined.

Events in the Semantics of English: A Study in Subatomic Semantics

TL;DR: Focusing on the structure of meaning in English sentences at a "subatomic" level - that is, a level below the one most theories accept as basic or "atomic" - Parsons asserts that the semantics of simple English sentences require logical forms somewhat more complex than is normally assumed in natural language semantics.

Learning to map sentences to logical form: structured classification with probabilistic categorial grammars

TL;DR: A learning algorithm is described that takes as input a training set of sentences labeled with expressions in the lambda calculus and induces a grammar for the problem, along with a log-linear model that represents a distribution over syntactic and semantic analyses conditioned on the input sentence.

From treebank to propbank

TL;DR: This paper describes the approach to the development of a Proposition Bank, which involves the addition of semantic information to the Penn English Treebank and introduces metaframes as a technique for handling similar frames among near− synonymous verbs.
