There Is No Logical Negation Here, But There Are Alternatives: Modeling Conversational Negation with Distributional Semantics
Alternatives Distributional Semantics
2017/4/6
Logical negation is a challenge for distributional semantics, because predicates and their negations
tend to occur in very similar contexts, and consequently their distributional vectors are
very si...
RELPRON: A Relative Clause Evaluation Data Set for Compositional Distributional Semantics
Distributional Semantics assessment
2017/4/6
This article introduces RELPRON, a large data set of subject and object relative clauses, for
the evaluation of methods in compositional distributional semantics. RELPRON targets an
intermediate lev...
Integrating Type Theory and Distributional Semantics: A Case Study on Adjective–Noun Compositions
Integrating Type Theory Distributional Semantics
2017/4/6
In this article, we explore an integration of a formal semantic approach to lexical meaning and an
approach based on distributional methods. First, we outline a formal semantic theory that aims
to c...
Aligning Packed Dependency Trees: A Theory of Composition for Distributional Semantics
Dependency Trees Distributional Semantics
2017/4/6
We present a new framework for compositional distributional semantics in which the distributional
contexts of lexemes are expressed in terms of anchored packed dependency trees. We show
that these s...
Formal Semantics and Distributional Semantics are two very influential semantic frameworks
in Computational Linguistics. Formal Semantics is based on a symbolic tradition and
centered around the inf...
Probabilistic Distributional Semantics with Latent Variable Models
Distributional Semantics Latent Variable Models
2015/9/14
We describe a probabilistic framework for acquiring selectional preferences of linguistic predicates and for using the acquired representations to model the effects of context on word meaning. Our fra...
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 ...
