Davide Merlitti, Micaela Procaccia, Umberto Parrini, Maria Emilia Masci (2012)  La digital library “SHOAH” dell’ Archivio Centrale dello Stato : Un progetto di recupero e di digital preservation di documenti audiovisivi di storia orale   SCIRES-IT SCIentific RESearch and Information Technology Ricerca Scientifica e Tecnologie dell'Informazione 2: 2.  
Abstract: It La digital library âTi Racconto la Storia : Voci dalla Shoahâ (sito web: è il risultato di un progetto durato diversi anni, nato con lâobiettivo di preservare e diffondere un considerevole patrimonio documentario audiovisivo che il Ministero per i Beni e le Attività Culturali ha ricevuto in copia dalla Survivors of the Shoah Visual History Foundation nellâambito di un accordo di collaborazione. La trasformazione di un sistema software proprietario per lâindicizzazione dei contenuti e lâarchiviazione digitale in un sistema di digital library più attuale, basato sulle tecnologie più recenti, ha consentito di definire un modello per il recupero, la preservazione e la diffusione di risorse digitali adatto ad essere impiegato in qualsiasi ambito della storia orale. En The digital library âTi Racconto la Storia : Voci dalla Shoahâ (website: is the result of a project carried out for several years, aimed at the preservation and diffusion to the broad public of a huge audio-visual documentary heritage that the Italian Ministry for Cultural Heritage and Activities received in copy from the Survivors of the Shoah Visual History Foundation, in the context of a collaboration agreement. The transformation of a pre-existing proprietary software for the indexing and storage of digital resources into a modern Digital Library system, based on the most recent technologies, permitted to define a generic model for the recovery, preservation and dissemination of digital resources, that can be re-used for similar projects in the field of oral history.
S Tofanelli, L Taglioli, D Merlitti, G Paoli (2011)  Tools which simulate the evolution of uni-parentally transmitted elements of the human genome   Journal of Anthropological Sciences 89: 1-20  
Abstract: Several simulators have been recently developed in the field of evolutionary genetics which make it possible to test empirical data under hypotheses of genetic variation generated by evolutionary causes. In the perspectives opened in the post-genomic era, they need to meet the growing demand for flexible and computationally efficient algorithms capable of managing genome-wide population datasets. Backward and forward-in-time strategies are available when attempting to better understand the complexity of the evolutionary scenarios actually followed by real populations. However, both strategies have a number of pros and cons. Although non recombinant uni-parentally inherited (NRUP) haplotypes, as the variants of the mitochondrial genome and the majority of Y chromosome polymorphisms, have been an invaluable source of genetic information during the last two decades of molecular anthropological research, few dedicated programs have been designed to model their evolution. The present paper is a brief comparative and annotated overview of the simulation tools developed in the field of population genetics which can be applied to large NRUP data in order to test complex hypotheses concerning genetic variation from a human evolutionary perspective.

Abstract: To investigate the male genetic legacy of the Arab rule in southern Europe during medieval times, we focused on specific Northwest African haplogroups and identified evolutionary close STR-defined haplotypes in Iberia, Sicily and the Italian peninsula. Our results point to a higher recent Northwest African contribution in Iberia and Sicily in agreement with historical data. southern Italian regions known to have experienced long-term Arab presence also show an enrichment of Northwest African types. The forensic and genomic implications of these findings are discussed.

Second European Conference, ECDL’98 Heraklion, Crete, Greece September 21–23, 1998 Proceedings Springer Berlin / Heidelberg  
Abstract: The primary objective of the CiBIT digital library is the widest possible diffusion of information on Italian art, literature and history. The aim of CiBIT is to allow scholars and other interested users throughout the world to access and study multimedia documentation (voice and image data are also included) containing all kinds of information on and describing different aspects of Italian culture. The following main areas of artistic and cultural interest are covered: philology, literature, linguistics, medieval and modern history, legal history, musicology. The intention is to make the CiBIT service available to students and scholars in university libraries and research institutes, in the first place, but also in libraries serving the general public. Main aims of the project are to allow users throughout the world (through Internet) to access and consult Italian cultural data, and to provide them with a series of sophisticated tools to process and analyse the textual material in various ways. The CiBIT query system, which is based on that of the DBT system1, has been completely developed in JAVA so that it can be used by all existing WEB browsers and can operate on all kinds of hardware and software platforms. Java applets have been implemented to provide the same level of functionality as the stand-alone DBT system. A multiserver middleware engine automatically selects the best host site depending on the particular requirements of a given query. The CiBIT digital library can be accessed through the consultation of a single text, of a set of texts, or of an entire corpus. Relevant subsets of texts in a corpus can be defined dynamically using the bibliographic data associated with the texts.

Abstract: The explosion of the social web leads to a completely new approach towards building of knowledge. The social approach to information sharing creates expectations of growth of the information assets and stimulates interest in contributing to the creation of new information and knowledge. This phenomenon is even more important within the domain of Cultural Heritage, if we consider that the concept of cultural asset is not restricted to the artistic masterpieces, but it includes everything which is part of culture and traditions. One of the main issues on the User Generated Content (UGC) is the lack of a uniform and agreed structure and tagging system (metadata), which makes uneasy to share knowledge on the web. Cultural heritage domain is inherently interdisciplinary and very rich in semantic associations. As such, it constitutes an excellent test bed for semantic web technologies and knowledge organisation. The LABC (LABoratories for Culture) project and its prototypal portal are aimed to develop an innovative multimedia web 3.0 platform enabling the capture, sharing, and enjoyment of data on tangible and intangible cultural heritage and landscape. The LABC platform is designed to collect digital cultural and environmental resources from a broad base of users, and to reformulate such contents into scientifically structured information, available to both generic and authoritative users. Information collected through this web portal will automatically be structured using Semantic Web tools and technologies. This allows users to search and browse contents with different options: classic text retrieval, clustered, and semantic. Moreover, the platform allows for the creation of various "Laboratories", i.e.: specialized environments, where a community of users can collaborate by entering and/or enriching information, which will then made available to the wider community of all users of the portal, and to the entire web community in general. Two important aspects fronted with the LABC project are the sharing of information and language standardization. In order to effectively share information, CIDOC CRM core ontology has been chosen as reference model. SKOS (Simple Knowledge Organization System) standard, defined by W3C to share vocabularies on the web, has been employed to codify, export and exchange the terminology used in within the portal domain. A specific component of the system, named SKOSware, manages vocabularies and thesauri in SKOS format. The entries of dictionaries and thesauri are uniquely identified by a Uniform Resource Identifier (URI). The SKOSware component allows for consultation and handling of vocabularies and thesauri, as well as validation by domain experts. Different types of users, with appropriate privilege levels, can contribute information: Professional users can contribute with highly structured information, using special forms, thus ensuring compliance with the national cataloguing standards (the system can also import data from authoritative sources). General users can also contribute contents using less rigid, more agile integration modules, and semantically enrich information (according to the approach known as folksonomy) using tags that can be chosen freely, or selected from existing vocabularies and thesauri, on which they can browse and select.

Abstract: The Italian Culture Portal will be a media for knowledge of Italian cultural tangible and untangible heritage. It will provide one access to existing digitised information and wider visibility to Museums, Libraries, Archives, and cultural Bodies. Without duplicating data, the Portal will harvest metadata from several data-sources, using the Protocol for Metadata Harvesting of OAI; metadata could be also provided to national and international Super-Portals. As metadata standard, Dublin Core has been adopted. On the basis of Qualified DC, defined to reduce loss of information and allow a more efficient retrieval, an Application profile (PICO AP) has been specially developed, introducing new Types, Element- Refinements and Encoding Schemes. This metadata schema will assure interoperability and allow indexing, browsing and query functions on the ensemble of information. Through the one access point of the Portal, users will find resources from various repositories browsing by Object Categories, Subjects, Places, Dates, and People.
