Metaphor Identification Using Verb and Noun Clustering
نویسندگان
چکیده
We present a novel approach to automatic metaphor identification in unrestricted text. Starting from a small seed set of manually annotated metaphorical expressions, the system is capable of harvesting a large number of metaphors of similar syntactic structure from a corpus. Our method is distinguished from previous work in that it does not employ any hand-crafted knowledge, other than the initial seed set, but, in contrast, captures metaphoricity by means of verb and noun clustering. Being the first to employ unsupervised methods for metaphor identification, our system operates with the precision of 0.79.

Types of Grammatical Metaphors in Harry Potter and the Prisoner of Azkaban
Grammatical Metaphor (GM) is one of the fresh language phenomena introduced by Halliday (1985) in the framework of functional grammar. Thompson (2004) states that the salient source of GM would be ‘Nominalization’ where a noun form attempts to represent a verb form or in other words, a verb form with its different process is represented in a noun form. He continues that any wording is ought to ...
متن کاملA Computational Model of Metaphor Understanding: Based on a Statistical Analysis of a Japanese Corpus
This study constructs a computational model that realizes the understanding processes for metaphorical expressions, represented in the form of "A like B". Metaphor understanding basically requires a knowledge structure for concepts (a target, a vehicle and so on). However, it is not practically feasible to collect sufficient data to cover enough concepts by psychological methods alone, because ...
متن کاملParallelized Power Iteration Clustering of Nouns and Verbs using Subject-Verb and Verb-Object Pairs
We explore the use of Power Iteration Clustering for large-scale clustering of nouns and verbs, using subject-verb-object triple relations. We have implemented a parallelized version of PIC, which can efficiently handle clustering of hundreds of thousands of sparse “documents.” We tested our implementation on clustering of over 1 million noun phrases, and over 650K verb phrases. We also evaluat...
متن کاملUsing Loglinear Clustering for Subcategorization Identification
In this paper we will describe a process for mining syntactical verbal subcategorization, i.e. the information about the kind of phrases or clauses a verb goes with. We will use a large text corpus having almost 10,000,000 tagged words as our resource material. Loglinear modeling is used to analyze and automatically identify the subcategorization dependencies. An unsupervised clustering algorit...
متن کاملIdeational Grammatical Metaphor in Merry Shelly’s Frankenstein and its Cinematic Adaptation
Within Systemic Functional Linguistics, Grammatical Metaphor (GM) is a meaning-making resource lying at the experiential level that extends the meaning potential through cross-stratal re-mappings between the grammar and the semantics, boiling down, in one of its manifestations to expressing something that should have been a process (verb) in terms of a thing (noun). This study is an attempt at ...
