Catalogue of E-RIHS resources and services
Meghini C., Benassi L., Galeotti M., Bartalesi V., Concordia C., Castillejo M., Calvo C., Andreassi E., Striova J.
The Deliverable 8.1 describes the work carried in Task 8.3 "Catalogue of E-RIHS resources and services". With the term resource we intend any entity that may be of interest to a Infrastructure such as the one that the E-RIHS PP project is setting up, i.e. mainly datasets and services, but also people, organizations, instruments, and other entities. The catalogue aims at providing researchers with information related to Heritage Science resources available within E-RIHS through a formal model that helps categorising them according to their different features. Such features will also be used for discovering the resources in the Catalogue. The catalogue structure was designed to serve as the basis for accounting in-kind contributions and, in perspective, to be a single access point for resource discovery and access services.Source: Research report, E-RIHS PP, 739503, 2020

Introducing narratives in Europeana: a case study
Meghini C., Bartalesi V., Metilli D., Benedetti F.
We present a preliminary study to introduce narratives as a first-class functionality in digital libraries. The general idea is to enrich those libraries with semantic networks of events providing a meaningful contextualisation of the digital libraries' objects. More specific motivations are presented through a set of use cases by different actors who would benefit from using narratives for different purposes. Then, we consider a specific digital library, Europeana, the largest European digital library in the cultural heritage domain. We discuss how the Europeana Data Model could be extended for representing narratives, and we introduce an ontology for narratives. We also present a semi-automatic tool, which, on the basis of the ontology, supports the creation and visualisation of narratives, and we show how the tool has been employed to create a narrative of the life of the painter Gustav Klimt as a case study. In particular, we focus our attention on the functionality of the tool that allows extracting and proposing to the user specific digital objects for each event of the narrative.Source: International Journal of Applied Mathematics and Computer Science 29 (2019): 7–16. doi:10.2478/amcs-2019-0001

Populating narratives using Wikidata events: an initial experiment
Metilli D., Bartalesi V., Meghini C., Aloia N.
The study presented in this paper is part of our research aimed at improving the search functionalities of current Digital Libraries using formal narratives. Narratives are intended as sequences of events. We present the results of an initial experiment to detect and extract implicit events from the Wikidata knowledge base in order to construct a narrative in a semi-automatic way. Wikidata contains many historical entities, but comparably few events. The reason is that most events in Wikidata are represented in an implicit way, e.g. by listing a date of birth instead of having an event of type "birth". For this reason, we decided to generate what we call the Wikidata Event Graph (WEG), i.e. the graph of implicit events found in Wikidata. We performed an initial experiment taking as case study the narrative of the life of Italian poet Dante Alighieri. Only one event of the life of Dante is explicitly represented in Wikidata as instance of the class Q1190554 Occurrence. Using the WEG, we were able to automatically detect 31 more events of Dante's life that were present in Wikidata in an implicit way.Source: ICRDL 2019 - 15th Italian Research Conference on Digital Libraries, pp. 159–166, Pisa, Italy, 31 Juanry - 01 February 2019

A Wikidata-based tool for building and visualising narratives
Metilli D., Bartalesi V., Meghini C.
In this paper we present a semi-automatic tool for constructing and visualising narratives, intended as networks of events related to each other by semantic relations. The tool obeys an ontology for narratives that we developed. It retrieves and assigns internationalised resource identifiers to the instances of the classes of the ontology using Wikidata as an external knowledge base and also facilitates the construction and contextualisation of events, and their linking to form the narratives. The knowledge collected by the tool is automatically saved as an Web ontology language graph. The tool also allows the visualisation of the knowledge included in the graph in simple formats like tables, network graphs and timelines. We have carried out an initial qualitative evaluation of the tool. As case study, an historian from the University of Pisa has used the tool to build the narrative of Dante Alighieri's life. The evaluation has regarded the effectiveness of the tool and the satisfaction of the users' requirements.Source: International journal on digital libraries (Internet) 20 (2019): 417–432. doi:10.1007/s00799-019-00266-3

Steps towards a system to extract formal narratives from text
Metilli D., Bartalesi V., Meghini C.
In this paper we present a first step towards a system to extract for- mal narratives from text. This work is part of a wider research on the introduction of narratives in Digital Libraries. We represent narratives as networks of events, each set in space and time, endowed with factual components, and linked to each other through semantic relations. In order to extract a narrative from text, the first step is to automatically detect and classify the events in the text. We present a software we developed that uses neural networks for event detection and classifica- tion. It was trained on a dataset of annotated biographies of writers and artists from the English Wikipedia and on the ACE 2005 training corpus. We tested the software on the biography of Florentine poet Dante Alighieri. This software constitutes the first component of a broader system for narrative extraction from natural language text.Source: Text2Story 2019 - Second Workshop on Narrative Extraction From Texts, pp. 53–61, Cologne, Germany, 14 April 2019

Sistemi basati su ontologie per le Digital Humanities
Meghini C., Bartalesi V., Benedetti F., Metilli D.
Un sistema informativo per le Digital Humanities (DH per brevità) é visto come un agente che manipola conoscenza, essendo in grado di accogliere conoscenza dal mondo esterno (funzione di TELL) e di elaborarla in modo appropriato per rispondere a domande relative alla conoscenza posseduta (funzione di ASK). Il nostro gruppo ha fatto propria questa visione e sta lavo-rando da qualche anno ad applicarla nel settore delle DH. La seconda Sezione del paper descrive due progetti in cui tale visione si è esplicata. Nella prima sezione, si argomenta perché la visione risulti paricolarmente fruttuosa per le DH, al di là dei vantaggi che essa porta da un punto di vista ingegneristico.Source: Ital-IA 2019 - Workshop AI for Cultural Heritage, Roma, Italy, 18 marzo 2019

Constructing narratives using NBVT: a case study
Bartalesi V., Metilli D., Meghini C.
Narratives are a fundamental part of human life, starting from the epic poems of the ancient past to modern films. Since the 1970s, much research has been carried out to study the computational representation of narratives. Up to now, there is no standard definition of narrative. In our research, we intend narratives as networks of events defined by a narrator, endowed with participating entities (e.g. persons, location, time) and semantic relations. In this paper, we introduce the Narrative Building and Visualising Tool (NBVT), a semi- automatic software based on a formal ontology for narratives we developed. The tool allows users to construct and visualise narratives using Wikidata as reference knowledge base and Europeana for enriching the narrative with digital objects. As case study, we present the narrative of the life of the Austrian painter Gustav Klimt created using NBVT. Since Wikidata is not event-based, our efforts focus on the automatic extraction from Wikidata of the implicit events that compose the narrative. Furthermore, we developed a dedicated functionality in NBVT that finds the Europeana digital objects related to a particular event. This functionality matches the metadata of Europeana digital objects with the event and the participating entities using a similarity algorithm.Source: 8th AIUCD Conference 2019, pp. 169–171, Udine, Italy, 22-25 January 2019

A data model-independent approach to big research data integration
Barralesi Lenzi V., Meghini C., Thanos C.
The paper addresses the data integration problem in the context of the scientific domain. The main characteristics of the big research data that make the traditional approach of data integration unfeasible are presented. Two new emerging practices, i.e. an exploratory approach to data seeking and an empiricist epistemological approach to knowledge creation, are discussed. Based on these considerations, we present a new paradigm of data integration and an application ontology that supports it. The ontology is based on five types of events and every event is extensionally modelled as an input/output operation on the involved data entity. The strong point of the ontology and of the whole approach to data integration is that no assumption is made on the data models in which the databases or the views are expressed. This provides a level of generality that successfully deals with the heterogeneity of the domain.Source: International journal of metadata, semantics and ontologies (Print) 13 (2019): 330–345. doi:10.1504/IJMSO.2019.102680

Big research data integration
Bartalesi Lenzi V., Meghini C., Thanos C.
The paper presents a vision about a new paradigm of data integration in the context of the scientific world, where data integration is instrumental in exploratory studies carried out by research teams. It briefly overviews the technological challenges to be faced in order to successfully carry out the traditional approach to data integration. Then, three important application scenarios are described in terms of their main characteristics that heavily influence the data integration process. The first application scenario is characterized by the need of large enterprises to combine information from a variety of heterogeneous data sets developed autonomously, managed and maintained independently from the others in the enterprises. The second application scenario is characterized by the need of many organizations to combine information from a large number of data sets dynamically created, distributed worldwide and available on the Web. The third application scenario is characterized by the need of scientists and researchers to connect each others research data as new insight is revealed by connections between diverse research data sets. The paper highlights the fact that the characteristics of the second and third application scenarios make unfeasible the traditional approach to data integration, i.e., the design of a global schema and mappings between the local schemata and the global schema. The focus of the paper is on the data integration problem in the context of the third application scenario. A new paradigm of data integration is proposed based on the emerging new empiricist scientific method, i.e., data driven research and the new data seeking paradigm, i.e., data exploration. Finally, a generic scientific application scenario is presented for the purpose of better illustrating the new data integration paradigm, and a concise list of actions that must be performed in order to successfully carry out the new paradigm of big research data integration is described.Source: International Workshop on Information Search, Integration, and Personalization, pp. 23–37, Fukuoka, Japan, 14/05/ 2018, 15/05/2018

What is needed to digitise knowledge on Heritage Crafts?
Zabulis X., Meghini C., Partarakis N., Kaplanidi D., Doulgeraki P., Karuzaki E., Stefanidi E., Evdemon T., Metilli D., Bartalesi V., Fasoula M., Tasiopoulou E., Beisswenger C.
Heritage Crafts (HCs) involve tangible craft artefacts, materials, and tools and encompass traditional craftsmanship as a form of Intangible Cultural Heritage. Intangible HC dimensions include dexterity, know-how, and skilled use of tools, as well as identity and traditions of the communities in which craftsmanship is, or was, practiced. Despite their cultural significance, efforts towards HC digital representation and presentation are scattered. In the Mingei EU Innovation Action, an approach is developed towards systematising the representation of Heritage Crafts as Cultural Heritage for their preservation. The representation is expected to capture the wide spectrum of knowledge topics that HCs cover, from objects and their making, to hand gestures and tool uses that define craft motor skills, to the societal value, economic impact, and historical significance. In this article, we focus on the approach towards the creation of a knowledge and its representation. Examples and experiments are presented for two craft instances that are studied in this action.Source: Memoriamedia 1 (2019): 1–25.

A web application for exploring primary sources: the DanteSources case study
Bartalesi V., Meghini C., Metilli D., Tavoni M., Andriani P.
We present the methodological and technical process we adopted to develop DanteSources, a Web application that allows free access to the knowledge about Dante Alighieri's primary sources, i.e. the works of other authors that Dante cites in his texts. Up to now, this knowledge has been collected in many paper books, making it difficult for the scholars to retrieve it and to produce a complete overview of these data. Using Semantic Web technologies, we developed an ontology expressed in the Resource Description Framework Schema vocabulary providing the terms to represent this knowledge in a machine-readable form. A semi-automatic tool helps the scholars to populate the ontology with the data included in authoritative paper commentaries to Dante's works. Then, the tool automatically saves the resulting Resource Description Framework graph in a triple store. On top of this graph, we developed DanteSources, a Web application that allows users to extract and display the information stored in the knowledge base in the form of charts and tables. Finally, we report the results of a survey to collect suggestions from end-users on their interactions with DanteSources. The methodology and the tools we developed are easily reusable, e.g. to represent the knowledge about primary sources of other authors of the Italian and the international literature.Source: Digital Scholarship in the Humanities (2018). doi:10.1093/llc/fqy002

A Software Architecture for Narratives
Meghini C., Bartalesi V., Metilli D., Benedetti F.
The current Digital Libraries (DLs) usually return as answer of a user's query a ranked list of the resources included in the DLs but no semantic relation among the resources are reported. Using the Semantic Web technologies it is possible to improve these search functionalities introducing narratives as new search method. As narratives we intend semantic networks of events that are linked to the objects of the DLs and are endowed with a set of semantic relations that connect an event to another. These semantic networks may help the users to obtain a more complete knowledge on the subject of their searches. In this paper, we present a software architecture for building narratives in order to introduce them in DLs. Our architecture is composed of several tools (automatic and semi-automatic tools) for creating, storing and visualizing narratives. When possible, we reused open source components already available on-line, and for the software we developed, we freely distribute it for research aims.Source: IRCDL 2018 - 14th Italian Research Conference on Digital Libraries, pp. 23–29, Udine, Italy, 25-26 January 2018

Using an ontology for representing the knowledge on literary texts: the Dante Alighieri case study
Bartalesi Lenzi V., Meghini C.
This paper describes a digital library developed within the "Towards a Digital Dante Encyclopaedia" project, a three years Italian National Research Project that aims at building services supporting scholars in creating, evolving and consulting a digital encyclopaedia of Dante Alighieri's works. The digital library is based on a knowledge base storing knowledge on the primary sources that Dante refers to in his works, i.e. the works of other authors Dante refers to in his texts. At present, this information is scattered on many paper books, making it difficult to systematically overview the cultural background of Dante and to obtain a well-founded perception of how this background was gradually set up in time. The same applies also to other authors, therefore the applicability of our work extends well beyond the specific author we are considering in our project. The digital library that we are building is based on an ontology for representing the knowledge on one author's works and on the primary sources embedded in the commentaries to these works. Following this approach, a semantic network of Dante's works and of references to primary sources of these works was created. Furthermore, a web application allowing users to explore the semantic network in various ways and to visualize statistical information about the references as charts and tables was developed.Source: Semantic web (Print) 8 (2017): 385–394. doi:10.3233/SW-150198

Formal components of narratives
Bartalesi Lenzi V., Meghini C.
One of the main problems of the current Digital Libraries (DLs) is the limitation of the informative services offered to the users, who express their queries in natural language. Indeed, DLs provide simple search functionalities that return a list of the information objects contained in them. No semantic relation among the returned objects is usually reported, which could help the user in obtaining a more complete knowledge on the subject of the search. The introduction of the Semantic Web, and in particular of the Linked Data, has the potential of improving the search functionalities of DLs. In this context, our final aim is to introduce the narrative as new first-class search functionality. As output of a query, the new search functionality does not only return a list of objects but it also presents a narrative, composed of events that are linked to the objects of the library and endowed with a set of semantic relations connecting these events into a meaningful semantic network. This paper presents a study of the Artificial Intelligence literature, especially of the Event Calculus theory, in order to identify the formal components of narratives. Furthermore, the mapping between these components and the standard ontology CIDOC CRM is presented, in order to evaluate if it could be taken as reference vocabulary to create an ontology for narratives. On the top of this ontology, we will develop the new search functionality for DLs.Source: Digital Libraries and Multimedia Archives, edited by Agosti Maristella, Bertini Marco, Ferilli Stefano, Marinai Simone, Orio Nicola, pp. 112–121, 2017

The Narrative Building and Visualising Tool (NBVT) is a semi-automatic tool to construct and visualise narratives, intended as semantic networks of events related each other through semantic relations. This tool obeys an ontology for narratives. NBVT uses Wikidata/Wikimedia Commons as external knowledge base of images and entities. The user of NBVT can select instances of the narratives ontologies among automatically proposed Wikidata entities, otherwise new entities can be created. NBVT assigns URIs to the selected instances and facilitates the construction of events based on these instances, and their linking to form narratives. The knowledge collected by the tool is exported as Linked Data.Project(s): PARTHENOS via OpenAIRE

A conceptualisation of narratives and its expression in the CRM
Bartalesi Lenzi V., Meghini C, Metilli D.
Current Digital Libraries (DLs) are mostly built around large collections of scarcely related objects. We aim at enriching the information space of DLs by introducing narratives, consisting of two main components: networks of events related to one another and to the DL resources through semantic links, and narrations of those events in texts. In order to introduce narratives in DLs, we developed a conceptualisation based on narratology and we expressed it using the CIDOC CRM and CRMinf as reference ontologies. We used this expression to validate our conceptualisation, creating a narrative of the biography of Dante Alighieri as a realistic case study. To support this experiment, we developed a semi-automated tool that collects basic knowledge about objects and events from Wikidata. The developed ontology is general enough to be not limited to create biographies but other types of narratives as well.Source: International journal of metadata, semantics and ontologies (Online) 12 (2017): 35–46. doi:10.1504/IJMSO.2017.087692
