Composing or not composing
Understanding how language comprehension works remains a central challenge. While meaning is traditionally viewed as incrementally constructed through compositional processes, numerous studies show that non-compositional mechanisms also play a crucial role. In this paper, we propose a unified framework grounded in Construction Grammar and Distributional Semantics that integrates both aspects. In this perspective, we extend Sign-Based Construction…
Collocation in the Mind
Collocational priming is a priming effect induced by collocationally related words; it has been taken to explain the cognitive reality of collocation. Collocational priming has largely been observed in first language (L1) speakers, whereas work on the representation of collocation in a second language (L2) is still limited. In the present study, we sought to investigate this phenomenon in L1 and L2 speakers of Italian. We used a lexical decision …
Constructional associations trump lexical associations in processing valency coercion
The paper investigates the interaction of lexical and constructional meaning in valency coercion processing, and the effect of (in)compatibility between verb and construction for its successful resolution (Perek, Florent & Martin Hilpert. 2014. Constructional tolerance: Cross-linguistic differences in the acceptability of non-conventional uses of constructions. Constructions and Frames 6(2). 266–304; Yoon, Soyeon. 2019. Coercion and language chan…
Decoding Word Embeddings with Brain-Based Semantic Features
Word embeddings are vectorial semantic representations built with either counting or predicting techniques aimed at capturing shades of meaning from word co-occurrences. Since their introduction, these representations have been criticized for lacking interpretable dimensions. This property of word embeddings limits our understanding of the semantic features they actually encode. Moreover, it contributes to the “black box” nature of the tasks in w…
Valency coercion in Italian
The paper investigates valency coercion effects in Italian by means of an acceptability rating task on nine argument structure constructions. The experimental design follows Perek & Hilpert (2014) in presenting three conditions: grammatical, impossible and coercion stimuli. This design allows us to test several factors: the acceptability of creative coerced structures, the role of age and – most importantly – the influence of the construction its…
Lexical fixedness and compositionality in L1 speakers’ and L2 learners’ intuitions about word combinations
The present investigation focuses on first language (L1) and second language (L2) speakers’ sensitivity to lexical fixedness and compositionality of Italian word combinations. Two studies explored language users’ intuitions about three types of word combinations: free combinations, collocations, and idioms. In Study 1, Italian Verb+Noun combinations were embedded in sentential contexts, with control conditions created by substituting the verb wit…
Distributional Models of Word Meaning
Distributional semantics is a usage-based model of meaning, based on the assumption that the statistical distribution of linguistic items in context plays a key role in characterizing their semantic behavior. Distributional models build semantic representations by extracting co-occurrences from corpora and have become a mainstream research paradigm in computational linguistics. In this review, I present the state of the art in distributional sema…

Verbs of visual perception in Italian FrameNet
In this paper, we present a frame semantic analysis of a small group of Italian verbs expressing visual perception, which constitutes the first stage of a project for developing an Italian FrameNet. Our results show a close correspondence between English and Italian perception-related frames. The main element of novelty in our approach is that the creation and annotation of Lexical Units is grounded in distributional information automatically acq…

Distributional Memory
Research into corpus-based semantics has focused on the development of ad hoc models that treat single tasks, or sets of closely related tasks, as unrelated challenges to be tackled by extracting different kinds of distributional information from the corpus. As an alternative to this "one task, one model" approach, the Distributional Memory framework extracts distributional information once and for all from the corpus, in the form of a set of wei…
Spazi di parole
The aim of this paper is to analyse the analogy of the lexicon with a space defined by words, which is common to a number of computational models of meaning in cognitive science. This can be regarded as a case of constitutive scientific metaphor in the sense of Boyd (1979) and is grounded in the so-called Distributional Hypothesis, stating that the semantic similarity between two words is a function of the similarity of the linguistic contexts in…
Simple
The project LE-SIMPLE is an innovative attempt at building harmonized syntacticsemantic lexicons for twelve European languages, intended for use in different Human Language Technology applications. SIMPLE provides a general design model for the encoding of a large amount of semantic information, ranging from ontological typing, to argument structure and terminology. SIMPLE thus provides a general framework for resource development, where state-of…
