This study focuses on discourse cohesion, specifically investigating three linguistic phenomena: reference, lexical repetition, and connectives. Six features related to these categories were defined and automatically extracted from an Italian corpus of semi-spontaneous speech, collected from patients with early dementia, MCI subjects, and healthy controls. Some of these features proved significant in distinguishing among the three groups. Additional quantitative analysis revealed notable differences in the use of these elements, suggesting a potential link between their degradation and cognitive decline.}, booktitle = {Tenth Swedish Language Technology Conference (SLTC)}, author = {Albertin, Giorgia and Kokkinakis, Dimitrios}, year = {2024}, pages = {4}, } @inProceedings{kokkinakis-2024-from-336089, title = {From Zipf distribution to Universal Dependencies - Interactive Notebooks for Swedish Text Analysis }, abstract = {Notebook-based environments are powerful (web-based) interactive development resources for conducting exploratory (textual) data analysis (EDA).

Shedding light on the political tensions that emerged as a result of the pandemic and the debates that ensued both within and between the Nordic nations, it investigates the vociferous discussions surrounding the COVID-19 vaccines and their presumed negative side effects through the lens of trust; trust in and between the neighbouring countries, in healthcare systems, fellow citizens, and experts; in public authorities, politicians, researchers, journalists, and pharmaceutical companies. The first volume to explore vaccine hesitancy in the Scandinavian context, this ground-breaking volume offers fresh perspectives on vaccine scepticism not as a form of ignorance or lack of knowledge, but as a manifestation of a more fundamental lack of faith in modern government and science. As such, it will appeal to scholars of sociology, politics, anthropology, media studies, communication and cultural studies with interests in public health, popular and political discourse and questions of public trust. }, author = {Borin, Lars and Hammarlin, Mia Marie and Kokkinakis, Dimitrios and Miegel, Fredrik}, year = {2024}, publisher = {Taylor and Francis}, ISBN = {9781040011614}, } @inProceedings{belmonte-etal-2024-automatic-336253, title = {Automatic Detection of Rhythmic Features in Pathological Speech of MCI and Dementia Patients }, abstract = {The presence of linguistic alterations represents one of the prodromal signs of cognitive decline associated with dementia. In recent years, a growing body of work has been devoted to the development of algorithms for the automatic linguistic analysis of both oral and written texts, with diagnostic purposes. The extraction of Digital Linguistic Biomarkers from patients' verbal productions can indeed provide a rapid, ecological, and cost-effective system for large-scale screening of the pathology. This article contributes to the ongoing research in the field by exploring a traditionally less studied aspect of language in dementia, namely the rhythmic characteristics of speech. In particular, the paper focuses on the automatic detection of rhythmic features in Italian connected speech. A landmark-based system was developed and evaluated to segment the speech flow into vocalic and consonantal intervals and to calculate several rhythmic metrics. Additionally, the reliability of these metrics in identifying MCI and dementia patients was tested.}, booktitle = {RaPID-5: Resources and ProcessIng of linguistic, para-linguistic and extra-linguistic Data from people with various forms of cognitive/psychiatric/developmental impairments}, author = {Belmonte, Marica and Gagliardi, Gloria and Kokkinakis, Dimitrios and Tamburini, Fabio}, year = {2024}, publisher = {European Language Resources Association (ELRA)}, ISBN = {978-2-493814-11-1}, } @inProceedings{kokkinakis-hammarlin-2024-cluster-338476, title = {Cluster-Based BERTopic Modeling on Swedish COVID-19 Vaccine Posts}, abstract = {This paper explores the prevalent themes across multiple threads on the popular Swedish discussion forum Flashback.
