Hello! I'm Marilena Daquino, assistant professor (RTDa) at the University of Bologna

I work at the /DH.arc (Digital Humanities Advanced Research Centre) of the University of Bologna. I have a PhD in Library and Information Science + Computer Science. My research focuses on the application of Semantic Web technologies to Humanities research data.


My background is in history and library and information science. I am fond of archival studies + semantic web!


Since 2014 I am a researcher in digital humanities at the Department of Classical Philology and Italian Studies of the University of Bologna, where I'm a member of the Digital Humanities Advanced Research Centre.


I used to work as a metadata specialist and ontology engineer at the Multimedia Research Centre (CRR-MM) of the University of Bologna for three years. I was visiting PhD student at the Knowledge Media Institute, Open University (UK).


My PhD is on digital hermeneutics, specifically, on the usage of Linked Open Data belonging to art historical photo archives to compare and recommend authoritative artwork attributions. During this period I had the pleasure to collaborate with several universities, consortia of museums (Linked.art) and photo archives (PHAROS).


Sometimes I provide consultancy to researchers and companies on Knowledge Organisation related aspects.
I am a member of the editorial board of Umanistica Digitale, the Italian Journal of Digital Humanities.
I also teach Information Visualization and Digital Humanities at the University of Bologna.

Art, Archives, Ontologies


An ongoing project to create the knowledge graph of art historians’ archives for historiographical research purposes. It is based on a native Linked Open Data cataloguing system bespokely developed for the project, that leverages on-the-fly data integration with Wikidata and NLP techniques to enrich cataloguers' descriptions with structured data. Several institutions contribute to the project, namely: the Federico Zeri Foundation (Bologna, Italy), University Roma Tre (Rome, Italy), Scuola Normale Superiore (Pisa, Italy), Biblioteca Hertziana (Rome, Italy), Kunsthistorisches Institut in Florenz (Florence, Italy), Getty Research Institute (Los Angeles, USA).



mAuth is a proof-of-concept semantic crawler and recommending system of artwork attributions. It allows to explore art historians' attributions - including motivations, bibliographic references, and images - about artworks of the Modern Art (15-16th centuries). It evaluates the methodology underpinning decisions made by art historical data providers, and ranks attributions according to their authoritativeness.

PhD thesis

Federico Zeri's catalogue Linked Open Dataset

The Linked Open Dataset of the Federico Zeri's photo archive. The dataset includes cataloguing data about 30K photographs depicting around 19K artworks from the Modern era, detailed information about artists and photographers, and the complete list of competing artwork attributions provided by the historians that visited the archive over time.

article (JOCCH 2017)

HiCO ontology

An extension of the PROV Ontology for describing hermeneutical aspects underlying scholars' competing attributions, such as motivations, sources, and relations with other claims. Currently used to describe art historians' attributions in the Zeri's dataset, in the digital edition of Paolo Bufalini's notebook, and Vespasiano da Bisticci's letters (and more!)

article (2015)

FEntry and OAEntry ontology

The ontologies developed to describe cataloguing records issued by the Federico Zeri's Foundation about photographs (FEntry) and artworks depicted in photographs (OAEntry). The ontologies are an extension of CIDOC-CRM, and include several other existing ontologies, such as the SPAR Ontologies, PROV-O, and HiCO.

PROles ontology

An ontology for the description of political relationships between people. Building upon existing ontological models, such as the Publishing Roles Ontology (PRO), PROV-O and the N-ary Participation ontology design pattern, PRoles provides a clear ontological characterisation of political roles and related events, establishing a link between the description of such concepts and the documents from which this information is extracted.

Text, Editions, Linked Open Data

Paolo Bufalini's notebook edition

A digital scholarly edition of the notebook of Paolo Bufalini that leverages Semantic Web technologies for creating, serving and analysing data underlying the full-text of the notebook. The dataset is based on ontologies such as the SPAR ontologies, HiCO, PROV-O, and the Nanopublication data model to (1) represent intertextual and intratextual relations, and (2) trace cited authors' opinions and claims on the history of literature. The web application is currently being restyled to experiment generous interfaces while close reading the text.

article (UD 2019)

Vespasiano da Bisticci's letters

A digital scholarly edition of the correspondance of Vespasiano da Bisticci. Data are served as Linked Open Data and include detailed information on the network of addressees, places, debated manuscripts, and peculiarities of the lexicon.


Past collaborations as metadata expert and web developer


The database of the Inscriptions of Greek Cyrenaica. It includes two corpora of XML/Epidoc documents, namely: The Inscriptions of Greek Cyrenaica (IGCyr) and the Greek Verse Inscriptions of Cyrenaica (GVCyr).


La Dama Boba

The digital edition and archive of Lope de Vega's works. Based on XML/TEI documents of 3 witnesses and a critical edition.


Scholarly data, Citations, Open Science

The Open Citations Data Model (OCDM)

The OpenCitations Data Model (OCDM) was initially developed in 2016 to describe the data in the OpenCitations Corpus (OCC). In recent years OpenCitations has developed other datasets while OCDM has been adopted by external projects. OCDM has been expanded to accommodate metadata requirements of the Open Biomedical Citations in Context Corpus project (CCC).

article (ISWC 2020)

The Open Biomedical Citations in Context corpus (CCC)

CCC is a Linked Open Dataset funded by the Wellcome Trust that enriches the OpenCitations Corpus (OCC) with detailed information on in-text references and their semantic context, making it possible to analyse references that are cited together at different points of the article (e.g. Introduction, Methods), and to distinguish the function of the citation.

SPARQL endpoint

RAMOSE, an API manager over SPARQL endpoints

A tool to create REST APIs over SPARQL endpoints via source-specific textual configuration files which enable the querying of SPARQL endpoints via Web RESTful API calls that return either JSON or CSV-formatted data. The objective is to hide the complexity of SPARQL and RDF from Web users.

BCite is a web interface to support journal editors in the management and correction of bibliographic references, and allows the creation of open citation data compliant with the OpenCitations Data Model

Music, Catalogues, Programming

musoW catalogue

Linked Open Data catalogue of online musical resources.

Semantic Web MIDI tape

CLI application to query and add data to the MIDI knowledge graph by playing your MIDI instrument and transforming MIDI tracks into Linked Open Data. After playing, the tool recommends related resources to users.

Scripting ontology

An ontology for describing the design and the execution of citizen curation activities, such as engagement activities with museum visitors, web applications for eliciting users' interpretations (e.g. via storytelling, question answering), social media interactions.
