Frame-Semantic Parsing
Frame-Semantic linguistics
2015/9/14
Frame semantics is a linguistic theory that has been instantiated for English in the FrameNet
lexicon. We solve the problem of frame-semantic parsing using a two-stage statistical model
that takes l...
Suppose we want to build a system that answers a natural language question by representing its
semantics as a logical form and computing the answer given a structured database of facts. The
core par...
Multiword expressions lie at the syntax/semantics interface and have motivated alternative
theories of syntax like Construction Grammar. Until now, however, syntactic analysis and
multiword expressi...
A Context-Theoretic Framework for Compositionality in Distributional Semantics
Context-Theoretic semantic
2015/9/10
Formalizing “meaning as context” mathematically leads to a new, algebraic theory of meaning,
in which composition is bilinear and associative. These properties are shared by other methods
that have ...
Learning Entailment Relations by Global Graph Structure Optimization
Structure Optimization Entailment Relations
2015/9/10
Identifying entailment relations between predicates is an important part of applied semantic
inference. In this article we propose a global inference algorithm that learns such entailment
rules. Fir...
Large-scale annotated corpora are a prerequisite to developing high-performance semantic role
labeling systems. Unfortunately, such corpora are expensive to produce, limited in size, and
may not be ...
We present a lexicon-based approach to extracting sentiment from text. The Semantic Orientation CALculator (SO-CAL) uses dictionaries of words annotated with their semantic orientation
(polarity and ...
A Graph-Theoretic Framework for Semantic Distance
Semantic Distance Graph-Theoretic Framework
2015/9/8
Many NLP applications entail that texts are classified based on their semantic distance (how
similar or different the texts are). For example, comparing the text of a new document to that of
d...
It is a standard assumption that subordinate clauses like relative, embedded declarative, and
interrogative clauses in natural language vary according to their morphosyntactic and semantic
character...
Relative embeddings: A Circassian puzzle for the syntax/semantics interface
relative clauses headless relatives
2015/9/6
This paper documents and analyzes the pattern used in the Northwest Caucasian
language Adyghe (Circassian) to express what the following five different constructions convey in
other languages: heade...
The role of the Imperfect in Romance Counterfactuals
role of the Imperfect Romance Counterfactuals
2015/9/6
The Imperfect in Romance is used in an array of constructions: progressives, habituals, generics and counterfactual conditionals. The first three all share hallmarks of the Romance Imperfect: they des...
Actuality Entailments
Actuality Entailments
2015/9/6
The term ‘actuality entailment’ was coined by Rajesh Bhatt in his 1999 dissertation to describe the implicative inference that arises when ability modals combine with perfective aspect. This article i...
Bootstrapping attitudes
acquisition syntactic bootstrapping propositional attitudes pragmatics implicatures presuppositions
2015/9/6
This paper explores two classic problems at the semantics-pragmatics interface from a learner’s perspective. First, the meaning that speakers convey often goes beyond the literal meaning of the senten...
多模态历史教科书中评价语义的图文双重建构
多模态历史语篇 图文关系 评价
2016/4/26
本文综合Martin关于文字、图像的评价理论(MartinWhite 2005)及其图文关系框架理论(MartinRose 2007),提出基于图文关系的多模态评价语义分析框架,以多模态历史教科书为例,从个案例示和数据统计来讨论多模态历史教科书中评价语义的图文双重建构及其作用。经统计和分析发现,文字评价和图像评价是一个有机的整体,图文评价受图文关系影响产生同步性。在多模态历史教科书语篇中,图像、文...
Assessing event perception in adults and prelinguistic children: A prelude to syntactic bootstrapping
prelinguistic children perception
2015/9/2
For a scene that can be described by 2-argument
sentences, and is perhaps viewed under 3-participant
concepts:
1) Do adults view the scene under a 3-participant concept?
2) Do in...
