This repository contains CSV files used in the study described above. The data were collected from human participants who provided metaphor interpretations and ratings, and from several Italian-trained language models whose normalized log-probabilities were computed on human interpretations and systematically constructed distractors.

🗂 Overview

The dataset contains 140 metaphors extracted from Italian parliamentary transcripts (Chamber of Deputies, 2008–2022). Human participants provided free-form interpretations for each metaphor and rated (1–5) the conventionality of the expression and the adequacy of the sentence context. For each metaphor there are two distractors created programmatically: a Literal Distractor (LD) and an Opposite Metaphorical Distractor (OMD). Several autoregressive LLMs (GePpeTto, Minerva family, LLaMAntino) were evaluated by computing log-likelihoods for each human interpretation and distractor; normalized log probabilities and ranks are provided.

Refer to the paper for full methodology and analyses.

m_id	string	Metaphor identifier (e.g., M1, M42)
gruppo_bilanciamento	string	Balancing group (G1–G7) corresponding to the syntactic pattern distribution
item	string	Full sentence containing the metaphor
v_term	string	Lexical item annotated as metaphorical
pattern	string	Syntactic pattern of the metaphor (e.g., N₁ di N₂, V ∼ N)
valenza	string	Valency of the metaphorical element (nessuno, intransitiva, transitiva)
classe_lessicale	string	Part of speech of the metaphorical element (e.g., N₁, Verbo, Aggettivo)
prompt	string	Sentence frame shown to participants for interpretation elicitation
avg_conv	numeric	Mean conventionality rating (1–5)
avg_cntxt	numeric	Mean context adequacy rating (1–5)
entropia di shannon	numeric	Shannon entropy of interpretation distribution (measure of variability)
consenso_max	numeric	Maximum consensus score (relative frequency of most common interpretation)
n_int	integer	Number of human interpretations collected for the item
