The deconstruction of gender stereotypes is essential to prevent discrimination, marginalization and gender-based violence. Despite the increasing attention to this issue, research in this field often focuses on explicitly sexist or hateful communication, leaving out all the cases where stereotypes are produced unconsciously or even with apparently positive intentions. Moreover, the identification and analysis of gender stereotypes is often a very subjective task, heavily influenced by the researcher’s background, beliefs and personal sensitivity. In this context GSI:detect, a dataset for gender stereotypes identification in Italian, has been annotated following a perspectivist approach that gives value to the different points of view of four annotators. It has been designed to address (i) the lack of resources focusing on naturally occurring and non-hateful language conveying implicit or ambiguous forms of gender stereotypes, and (ii) the scarcity of datasets that can capture multiple interpretations as well as the inherent variation and disagreement in human perception. Baseline experiments with several LLMs confirm the challenging nature and value of such a linguistic resource, revealing both apparent differences and limitations in performance among the evaluated models, and raising questions about the extent to which current LLMs are suitable for detection and classification tasks in this field. Content warning: Examples taken from the GSI:detect dataset may contain sensitive or potentially distressing content.

We introduce MAIA (Multimodal AI Assessment), a native-Italian benchmark designed for fine-grained investigation of the reasoning abilities of visual language models on videos. MAIA differs from other available video benchmarks for its design, its reasoning categories, the metric it uses, and the language and culture of the videos. MAIA evaluates Vision Language Models (VLMs) on two aligned tasks: a visual statement verification task, and an open-ended visual question-answering task, both on the same set of video-related questions. It considers twelve reasoning categories that aim to disentangle language and vision relations by highlighting the role of the visual input. Thanks to its carefully taught design, it evaluates VLMs’ consistency and visually grounded natural language comprehension and generation simultaneously through an aggregated metric revealing low results that highlight models’ fragility. Last but not least, the video collection has been carefully selected to reflect the Italian culture, and the language data are produced by native-speakers.Data available at GitHub.

Ellipsis is a linguistic phenomenon characterized by the omission of one or more sentence elements. Solving such a linguistic construction is not a trivial issue in natural language processing since it involves the retrieval of non-overtly expressed verbal material, which might in turn require the model to integrate human-like syntactic and semantic knowledge. In this paper, we explored the issue of how the prototypicality of event participants affects the ability of Language Models (LMs) to handle elliptical sentences and to identify the omitted arguments at different degrees of thematic fit, ranging from highly typical participants to semantically anomalous ones. With this purpose in mind, we built ELLie, the first dataset composed entirely of utterances containing different types of elliptical constructions, and structurally suited for evaluating the effect of argument thematic fit in solving ellipsis and reconstructing the missing element. Our tests demonstrated that the probability scores assigned by the models are higher for typical events than for atypical and impossible ones in different elliptical contexts, confirming the influence of prototypicality of the event participants in interpreting such linguistic structures. Finally, we conducted a retrieval task of the elided verb in the sentence in which the low performance of LMs highlighted a considerable difficulty in reconstructing the correct event.
