Semantic control for the Cybersecurity domain: investigation on the representativeness of a domain-specific terminology referring to lexical variation
(Università della Calabria, 2021-05-12) Lanza, Claudia; Guarasci, Roberto; Crupi, Felice
The underlying idea of this PhD research project is to develop a model meant to guarantee the terminological coverage of a semantic resource, such as a thesaurus, and its representativeness threshold with reference to semantic variation over time within a highly specialized domain, such as the Cybersecurity. By building an Italian thesaurus related to the Cybersecurity domain, this project wants to offer organizations a knowledge representation of the field of study in Information and Communications Technology (ICT) security as complete as possible. The development of an Italian thesaurus for the Cybersecurity knowledge domain is part of the activities included in the main project “Cybersecurity Observatory” held by the Institution of Informatics and Telematics (IIT) at the National Research Council (CNR) sited in Pisa (Italy). The thesis describes the steps followed for the construction of the Italian Cybersecurity thesaurus and for the assessment of a multi-domain methodology to fix a semantic representativeness threshold with reference to qualitative terms richness within a specialized domain and the variation in information related to the latter over time. The main phases henceforth described are related to (1) a presentation of the principal reasons for building a semantic tool, such as a thesaurus, as a means of semantic control for a specific domain; (2) a description of the steps which characterize the corpus creation and the terminological extraction through the use of specific Natural Language Processing (NLP) tasks and linguistic pattern configuration within the employed software; (3) the way a bilingual thesaurus and a bilingual ontology have been realized by creating parallel and comparable corpora; (4) a presentation of a model of mapping existing standards on Cybersecurity in English to all the head terms contained in the source corpus in Italian through Python scripts in order to evaluate which candidate terms should be chosen for inclusion in the thesaurus; (5) a descriptive section on the work done in migrating the terms and their relationships from the Italian thesaurus on Cybersecurity to an ontology system; (6) the phase related to keyphrases extraction, with the help of document oriented algorithms, i.e., Multipartite Rank or TopicRank, from the source documents. This was carried out to obtain a targeted clustering of the domain and as an aide in the process of semantic abstraction, needed to better systematize the structure of thesaurus’ main entry categories; (7) the exploration of new methodologies, i.e., distributional semantics, term variation, pattern-based detection schemes or inference from the Web Ontology Language (OWL) properties, to deduce the technical information included in the source corpus with the goal of automatically generating the semantic network of connections between the representative terms of the Cybersecurity domain in a thesaurus system; (8) a future perspective, accompanied by evolving examples in practice, of creating an additional database to populate the Cybersecurity source corpus through the use of the social media world. Twitter is one of the preferred web portals from which to retrieve information about the domain: this new information flow should give to the semantic resources, set up for Cybersecurity knowledge organization, an increased level of terminological density to be analyzed in order to improve the semantic coverage.

Equipaggiamento difensivo, armi individuali e tecniche d’assedio in Calabria e in Italia meridionale (sec. XIII-XV)
(Università della Calabria, 2023-10-05) Di Pietro, Francesco; Perrelli, Raffaele; Salerno, Mariarosaria
This doctoral dissertation examines the development of defensive equipment, individual weaponry, and siege technologies in Southern Italy—particularly in Calabria—between the thirteenth and fifteenth centuries, within the broader political and military framework of the Angevin domination. The study aims to reconstruct the material culture of war by integrating documentary, iconographic and archaeological evidence, in a region whose sources are often fragmentary due to the destruction of the Angevin Chancery Registers and the uneven survival of local archival materials. The research adopts a comparative and interdisciplinary methodology. First, it examines the Southern Italian case within the evolution of European military historiography and within the field of scientific hoplology, which has redefined the study of arms and armour over the past decades. Second, it relates documentary terminology—drawn from inventories, fiscal records, and administrative documents of both Neapolitan and Provençal origin—with the visual record preserved in sculptures, manuscript illuminations, funerary monuments, and painted cycles. This dual approach allows for a more accurate assessment of morphological changes in equipment, technological improvements, and the circulation of craftsmen, materials, and stylistic models between Provence, Tuscany, and the Kingdom of Naples. The first part of the thesis outlines the historiographical landscape and addresses methodological issues concerning the study of medieval warfare, including the renewed attention to logistics, recruitment, cavalry, operational practices, and the transformation of armies in the late Middle Ages. The second part focuses on the analysis of military equipment: defensive armour, offensive weapons, equestrian tools, and naval outfitting, highlighting technological developments between the early Angevin conquest and the Durazzesque period. Particular emphasis is placed on projectile weapons and the progressive introduction of gunpowder artillery, whose impact altered both battlefield dynamics and siege warfare. The final section examines the organization, recruitment, and deployment of the armies mobilized by the Neapolitan crown, with special attention to the interplay between feudal obligations, urban and rural levies, professional mercenaries, and Provençal contingents. The study reconstructs tactical and strategic patterns across several reigns—Charles I and II, Robert of Anjou, Joanna I, and Ladislaus—highlighting how military practices shaped territorial control, social structures, and the economic life of communities. The dissertation includes an extensive iconographic appendix and database, offering a comprehensive collection of military representations for medieval Calabria. Through this integrated approach, the work contributes to redefining the role of Southern Italy in the broader history of medieval warfare and in the technological and cultural exchanges that shaped European and Mediterranean military development.
