A Cohesion Graph Based Approach for Unsupervised Recognition of Literal and Non-literal Use of Multiword Expressions

چکیده
We present a graph-based model for representing the lexical cohesion of a discourse. In the graph structure, vertices correspond to the content words of a text and edges connecting pairs of words encode how closely the words are related semantically. We show that such a structure can be used to distinguish literal and non-literal usages of multi-word expressions.

A Cohesion-based Approach for Unsupervised Recognition of Literal and Nonliteral Use of Multiword Expression
Texts frequently contain expression whose meaning is not strictly literal, such as idioms. Idiomatic and non-literal expressions pose a major challenge to natural language processing technology as they often exhibit lexical and syntactic idiosyncrasies. We propose a novel unsupervised method for distinguishing literal and non-literal usages of expressions. Our method determines how well a liter...
متن کاملLiteral or idiomatic? Identifying the reading of single occurrences of German multiword expressions using word embeddings
Non-compositional multiword expressions (MWEs) still pose serious issues for a variety of natural language processing tasks and their ubiquity makes it impossible to get around methods which automatically identify these kind of MWEs. The method presented in this paper was inspired by Sporleder and Li (2009) and is able to discriminate between the literal and non-literal use of an MWE in an unsu...
متن کاملUnsupervised Recognition of Literal and Non-Literal Use of Idiomatic Expressions
We propose an unsupervised method for distinguishing literal and non-literal usages of idiomatic expressions. Our method determines how well a literal interpretation is linked to the overall cohesive structure of the discourse. If strong links can be found, the expression is classified as literal, otherwise as idiomatic. We show that this method can help to tell apart literal and non-literal us...
متن کاملDetecting and Processing Figurative Language in Discourse
Figurative language poses a serious challenge to NLP systems. The use of idiomatic and metaphoric expressions is not only extremely widespread in natural language; many figurative expressions, in particular idioms, also behave idiosyncratically. These idiosyncrasies are not restricted to a non-compositional meaning but often also extend to syntactic properties, selectional preferences etc. To d...
متن کاملUnsupervised Classification of Verb Noun Multi-Word Expression Tokens
We address the problem of classifying multiword expression tokens in running text. We focus our study on Verb-Noun Constructions (VNC) that vary in their idiomaticity depending on context. VNC tokens are classified as either idiomatic or literal. Our approach hinges upon the assumption that a literal VNC will have more in common with its component words than an idiomatic one. Commonality is mea...
