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 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.2017.10008654

Using Formal Narratives in Digital Libraries
Meghini C., Bartalesi V., Metilli D.
Currently, Digital Libraries (DLs) provide simple search functionalities to respond to the user's queries, which return a ranked list of the resources included in the DLs. No semantic relation among the returned objects is usually reported that could help the user to obtain a more complete knowledge on the subject of the search. The introduction of the Semantic Web and in particular of the Linked Open Data has the potential of improving the search functionalities of DLs. In this context, the long-term aim of our study has been to introduce the narrative as new first-class search functionality of DLs. We intend narratives as 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. In this paper, we report an overview of the main ontologies for representing events and of the tools developed in the Semantic Web field to visualize events and narratives. This overview is needed for achieving the first goal of our research, that is the development of an ontology for representing narratives and, on the top of this ontology, a tool to construct and visualize narratives using the digital objects included in DLs.Source: edited by Costantino Grana, Lorenzo Baraldi, pp. 83–94, 2017

Usability evaluation of the digital library dantesources
Bartalesi V., Meghini C., Metilli D., Andriani P.
In this paper we present DanteSources, a Digital Library of Dante Alighieri's primary sources, i.e. the works of other authors that Dante cites in his texts. Currently, this information is scattered in many books, making it difficult for the scholars to retrieve it and also to produce a systematical overview of the cultural background of Dante. In order to overcome this problem, an ontology expressed in RDF/S was developed to represent this knowledge. Once the ontology had been defined, we populated it with the data included in authoritative commentaries to Dante's works. We stored the resulting RDF graph into a Virtuoso triple store. Finally, on top of this graph, we developed DanteSources, which allows users to extract and display the knowledge stored in the knowledge base in the form of charts and tables. In this paper we present the results of a survey to collect suggestions and comments from end-users on their interactions with DanteSources in order to evaluate its usability.Source: HCI International 2016 - Human-Computer Interaction.

Steps towards a formal ontology of narratives based on narratology
Bartalesi Lenzi V., Meghini C., Metilli D.
Narrative is emerging as a notion that may enable overcoming the limitations of the discovery functionality (only ranked lists of objects) offered by information systems to their users. We present preliminary results on modelling narratives by means of formal ontology, by introducing a conceptualization of narratives and a mathematical expression of it. Our conceptualization tries to capture fundamental notions of narratives as defined in narratology, such as fabula, narration and plot. A validation of the conceptualization and of its mathematical specification is ongoing, based on the Semantic Web standards and on the CIDOC CRM ISO standard ontology.Source: 7th Workshop on Computational Models of Narrative, pp. 4–10, Kraków, Poland, 11-12 July 2016

DanteSources: a digital library for studying Dante Alighieri's primary sources
Bartalesi Lenzi V., Meghini C., Metilli D., Andriani P., Tavoni M.
We present DanteSources, a focused Digital Library that aims at building innovative services supporting scholars in creating, evolving and consulting a digital encyclopaedia of Dante Alighieri's works. DanteSources is endowed with Web services that allow extracting and visualizing data about Dante Alighieri's primary sources, i.e. other authors' works which Dante referred to in his own works. The heart of the digital library is a knowledge base built on an ontology that was developed in the RDF/S language, representing Dante's works and the knowledge about them, extracted from some authoritative commentaries. Finally, on top of this graph, we developed DanteSources, which allows users to extract and display the knowledge stored in the knowledge base in the form of charts and tables. The methodology and the tool we developed are easily reusable to represent the knowledge about primary sources of other authors of the Italian or the international literature.Source: Umanistica Digitale (2017): 119–128. doi:10.6092/issn.2532-8816/7250

Introducing narratives in Europeana: preliminary steps
Meghini C., Bartalesi Lenzi V., Metilli D., Benedetti F.
We present some preliminary steps towards the introduction of narratives as first-class citizens in digital libraries. The general idea is to enrich the digital libraries with events providing a rich contextualisation of the digital libraries' objects. More specific motivations are presented in the paper through a set of use cases by different actors who would benefit from using narratives for different purposes. We then consider a specific digital library, Europeana, the largest European digital library in the cultural domain. We discuss how the Europeana Data Model should be extended for representing narratives. We present a tool supporting the creation and the visualisation of narratives and we show how the tool has been employed to create a narrative of the life of the painter Gustav Klimt.Source: ADBIS 2017 New Trends in Databases and Information Systems. 21st European Conference on Advances in Databases and Information Systems, ADBIS 2017 and 1st workshop on Data Driven Approaches for Analyzing and Managing Scholarly Data, AMSD 2017, 1st workshop on Novel Techniques for Integrating Big Data, BigNovelTI 2017, 1st International workshop on Data Science: Methodologies and Use-Cases, DaS 2017, 2nd International workshop on Semantic Web for Cultural Heritage, SW4CH 2017, pp. 333–342, Nicosia, Cyprus, 24-27 September 2017

Steps towards accessing digital libraries using narratives
Meghini C., Bartalesi V., Metilli D.
One of the main problems of the current Digital Libraries (DLs) is the limitation of the informative services offered to the users. Indeed, DLs provide simple search functionalities which return a list of the information objects contained in them. No semantic relation among the returned objects is usually reported which can help the user in obtaining a more complete knowledge on the subject of the search. The introduction of the Semantic Web has the potential of improving the search functionalities of DLs. Many cultural institutions have represented their metadata into formal descriptions encoded by means of formal languages such as RDF and OWL. In this context, the aim of our research is to introduce the narrative as a new search functionality which does not only return a list of objects but 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. The paper presents the first theoretical achievements on a model for representing narratives.Source: 10th International Workshop on Artificial Intelligence for Cultural Heritage co-located with the 15th International Conference of the Italian Association for Artificial Intelligence (AI*IA 2016), pp. 10–17, Genova, Italy, 28 November 2016

Narrative building and visualising tool
Metilli D., Bartalesi Lenzi V., Meghini C.
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
