Exploring Metaphorical Senses and Word Representations for Identifying Metonyms
A metonym is a word with a figurative meaning, similar to a metaphor. Because
metonyms are closely related to metaphors, we apply features that are used
successfully for metaphor recognition to the task of detecting metonyms. On the
ACL SemEval 2007 Task 8 data with gold standard metonym annotations, our system
achieved 86.45% accuracy on the location metonyms. Our code can be found on
GitHub.Comment: 9 pages, 8 pages conten
Corpus Analysis and Lexical Pragmatics: An Overview
Lexical pragmatics studies the processes by which lexically encoded meanings are modified in use; well-studied examples include lexical narrowing, approximation and metaphorical extension. Relevance theorists have been trying to develop a unitary account on which narrowing, approximation and metaphorical extension are all explained in the same way. While there have been several corpus-based studies of metaphor and a few of hyperbole or approximation, there has been no attempt so far to test the unitary account using corpus data. This paper reports the results of a corpus-based investigation of lexical-pragmatic processes, and discusses the theoretical issues and challenges it raises
A pragmatic approach to proverb use and interpretation
Proverbs are interesting pieces of popular wisdom and tradition belonging to any culture, which
help us to foreground the values and shared beliefs held by a speech community. However, its
study has received little attention up to now. Thus, this dissertation research aims to analyze the
functions and uses of proverbs taking examples from English and Spanish them. In order to achieve this goal, we have applied Sperber and Wilson’s Relevant Theory to explain how
proverbs allow the speaker to express his/her intention in an implicit way. The findings
demonstrate that the main functions of proverbs are criticism, advice and warning. In addition,
we have offered an explanation of how their often ironical and metaphorical nature affects proverbs’ understanding. Besides, we have studied the use of the ellipsis in proverbs, which
takes place in familiar proverbs, analyzing how familiarity and unfamiliarity influences on
proverb use. Finally, we summed up our conclusions to achieve a better comprehension of proverbs’ functions and usesLos proverbios son ejemplos de sabiduría popular y tradición de cualquier cultura que nos
ayudan a descubrir los valores y creencias compartidas por una comunidad de hablantes. Sin
embargo, este estudio ha recibido poca atención hasta ahora. Por lo tanto, el propósito del
presente trabajo es describir las funciones y usos de los proverbios y refranes concentrándonos
en refranes de la lengua inglés y española para analizar y explicar las funciones y usos de los
proverbios en general. Para conseguir nuestro propósito hemos aplicado la Teoría de la
Relevancia de Sperber y Wilson a este estudio para explicar como ellos permiten al hablante
expresar su intención de forma implícita. Las conclusiones demostrarán que la mayor función de
los proverbios es la crítica, el consejo y advertencia. Además, hemos ofrecido una explicación
de cómo su frecuente naturaleza irónica y metafórica influye en la comprensión de los
proverbios. También hemos estudiado el uso de la elipsis en los proverbios, que toma lugar en
los proverbios familiares, analizando como la familiaridad o el desconocimiento influye en el
uso de los proverbios. Finalmente, resumiremos nuestras conclusiones para llegar a una mejor
comprensión de las funciones y usos de los proverbio
The Latent Relation Mapping Engine: Algorithm and Experiments
Many AI researchers and cognitive scientists have argued that analogy is the
core of cognition. The most influential work on computational modeling of
analogy-making is Structure Mapping Theory (SMT) and its implementation in the
Structure Mapping Engine (SME). A limitation of SME is the requirement for
complex hand-coded representations. We introduce the Latent Relation Mapping
Engine (LRME), which combines ideas from SME and Latent Relational Analysis
(LRA) in order to remove the requirement for hand-coded representations. LRME
builds analogical mappings between lists of words, using a large corpus of raw
text to automatically discover the semantic relations among the words. We
evaluate LRME on a set of twenty analogical mapping problems, ten based on
scientific analogies and ten based on common metaphors. LRME achieves
human-level performance on the twenty problems. We compare LRME with a variety
of alternative approaches and find that they are not able to reach the same
level of performance.Comment: related work available at http://purl.org/peter.turney
Predicting Human Metaphor Paraphrase Judgments with Deep Neural Networks
We propose a new annotated corpus for metaphor interpretation by paraphrase, and a novel DNN model for performing this task. Our corpus consists of 200 sets of 5 sen- tences, with each set containing one reference metaphorical sentence, and four ranked candi- date paraphrases. Our model is trained for a binary classification of paraphrase candidates, and then used to predict graded paraphrase ac- ceptability. It reaches an encouraging 75% ac- curacy on the binary classification task, and high Pearson (.75) and Spearman (.68) correla- tions on the gradient judgment prediction task
Multimodal Grounding for Language Processing
This survey discusses how recent developments in multimodal processing
facilitate conceptual grounding of language. We categorize the information flow
in multimodal processing with respect to cognitive models of human information
processing and analyze different methods for combining multimodal
representations. Based on this methodological inventory, we discuss the benefit
of multimodal grounding for a variety of language processing tasks and the
challenges that arise. We particularly focus on multimodal grounding of verbs
which play a crucial role for the compositional power of language.Comment: The paper has been published in the Proceedings of the 27 Conference

On the Impact of Temporal Representations on Metaphor Detection
State-of-the-art approaches for metaphor detection compare their literal - or
core - meaning and their contextual meaning using metaphor classifiers based on
neural networks. However, metaphorical expressions evolve over time due to
various reasons, such as cultural and societal impact. Metaphorical expressions
are known to co-evolve with language and literal word meanings, and even drive,
to some extent, this evolution. This poses the question of whether different,
possibly time-specific, representations of literal meanings may impact the
metaphor detection task. To the best of our knowledge, this is the first study
that examines the metaphor detection task with a detailed exploratory analysis
where different temporal and static word embeddings are used to account for
different representations of literal meanings. Our experimental analysis is
based on three popular benchmarks used for metaphor detection and word
embeddings extracted from different corpora and temporally aligned using
different state-of-the-art approaches. The results suggest that the usage of
different static word embedding methods does impact the metaphor detection task
and some temporal word embeddings slightly outperform static methods. However,
the results also suggest that temporal word embeddings may provide
representations of the core meaning of the metaphor even too close to their
contextual meaning, thus confusing the classifier. Overall, the interaction
between temporal language evolution and metaphor detection appears tiny in the
benchmark datasets used in our experiments. This suggests that future work for
the computational analysis of this important linguistic phenomenon should first
start by creating a new dataset where this interaction is better represented.Comment: 12 pages, 4 figure
Lexical typology : a programmatic sketch
The present paper is an attempt to lay the foundation for Lexical Typology as a new kind of linguistic typology.1 The goal of Lexical Typology is to investigate crosslinguistically significant patterns of interaction between lexicon and grammar
