Does gender make a difference? Comparing the effect of gender on children's comprehension of relative clauses in Hebrew and Italian
No full textIn this paper we assessed the effect of gender morphology on children's comprehension of object relatives in Hebrew and Italian. We compared headed object relative clauses in which the relative head (the moved object) and the intervening embedded subject have the same or different genders. The participants were 62 children aged 3;9–5;5, 31 speakers of Hebrew and 31 speakers of Italian. The comprehension of relative clauses was assessed using a sentence–picture matching task. The main result was that whereas gender mismatch sharply improved the comprehension of object relatives in Hebrew, it did not significantly affect comprehension in Italian. In line with our previous work (Friedmann et al., 2009), we propose that the children's problem in the comprehension of headed object relatives stems from the intervention of the embedded subject between the moved relative head and its trace. We ascribe the different behavior of children in Hebrew and in Italian to the different status of the gender feature in the two languages: in Hebrew, gender is part of the featural composition of the clausal inflectional head, hence it is part of the feature set attracting the subject, whereas in Italian, where tensed verbs are not inflected for gender, it is not. Under the assumption that intervention effects are amenable to the locality principle Relativized Minimality, it is expected that only features functioning as attractors for syntactic movement will enter into the computation of intervention. We thus account for the different effect of gender mismatch in object relative comprehension in the two developing systems. Thus, the main finding of this work is comparative in nature: there is no effect of gender per se; rather, the potential effect of gender is crucially modulated by the morphosyntactic status of the feature in each language
On the role of textual connectives in sentence comprehension: A new dataset for Italian
Full text linkIn this paper we present a new evaluation resource for Italian aimed at assessing the role of textual connectives in the comprehension of the meaning of a sentence. The resource is arranged in two sections (acceptability assessment and cloze test), each one corresponding to a distinct challenge task conceived to test how subtle modifications involving connectives in real usage sentences influence the perceived acceptability of the sentence by native speakers and Neural Language Models (NLMs). Although the main focus is the presentation of the dataset, we also provide some preliminary data comparing human judgments and NLMs performance in the two task
NL4AI 2023: Overview of the Seventh Workshop on Natural Language for Artificial Intelligence (NL4AI 2023)
No full textThe Natural Language for Artificial Intelligence (NL4AI) workshop serves as a platform to explore the area situated at the intersection between Natural Language Processing (NLP) and Artificial Intelligence (AI), with a special emphasis on recent activities carried out in both fields in Italy. The seventh edition of the workshop set a new record with 23 submissions, of which 18 were accepted. The submissions span a broad spectrum of topics, encompassing foundational NLP research, applied NLP, and works that bridge the realms of NLP and AI. Notably, this edition exhibited a growing international presence, featuring contributions from authors representing 9 countries. The submissions also reflect a diversity of languages (e.g., English, French, Italian) and modalities (e.g., text, vision), underscoring the workshop's commitment to inclusivity and comprehensive exploration
Conditioning Chat-GPT for Information Retrieval: The Unipa-GPT Case Study
Full text linkThis paper illustrates the architecture and training of Unipa-GPT, a Large Language Model based chatbot developed for assisting students in choosing a bachelor/master degree course at the University of Palermo. Unipa-GPT relies on gpt-3.5-turbo, it was presented in the context of the European Researchers' Night SHARPER event. In our experiments we adopted both the Retrieval Augmented Generation (RAG) approach and fine-tuning to develop the system. The whole architecture of Unipa-GPT is presented, both the RAG and the fine-tuned systems are compared, and a brief discussion on their performance is reported
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
