Compositionality in distributional semantics

Distributional Semantics and Compositionality 2011: Shared Task Description and Results

This paper gives an overview of the shared task at the ACL-HLT 2011 DiSCo (Distributional Semantics and Compositionality) workshop. We describe in detail the motivation for the shared task, the acquisition of datasets, the evaluation methodology and the results of participating systems. The task of assigning a numerical score for a phrase according to its compositionality showed to be hard. Man...

A Systematic Evaluation of Current Motivation for Explicit Compositionality in Distributional Semantics

Determining Compositionality of Word Expressions Using Word Space Models

This research focuses on determining semantic compositionality of word expressions using word space models (WSMs). We discuss previous works employing WSMs and present differences in the proposed approaches which include types of WSMs, corpora, preprocessing techniques, methods for determining compositionality, and evaluation testbeds. We also present results of our own approach for determining...

Category-theoretic quantitative compositional distributional models of natural language semantics

This thesis is about the problem of compositionality in distributional semantics. Distributional semantics presupposes that the meanings of words are a function of their occurrences in textual contexts. It models words as distributions over these contexts and represents them as vectors in high dimensional spaces. The problem of compositionality for such models concerns itself with how to produc...

Optimizing a Distributional Semantic Model for the Prediction of German Particle Verb Compositionality

In the work presented here we assess the degree of compositionality of German Particle Verbs with a Distributional Semantics Model which only relies on word window information and has no access to syntactic information as such. Our method only takes the lexical distributional distance between the Particle Verb to its Base Verb as a predictor for compositionality. We show that the ranking of dis...
