Models

Ontology created in the context of archives as an extension to CIDOC-CRM.

Datasets & Data Management Plan

Manual Transcriptions of Typewritten Digital Representations of Portuguese Cultural Heritage Documents from the 20th Century

The dataset includes manual transcriptions of typewritten digital representations of Portuguese cultural heritage documents from the 20th century, extracted from the Arquivo Nacional Torre do Tombo (ANTT).

Typewritten Digital Representations of Portuguese Cultural Heritage Documents from the 20th century

The dataset has typewritten Portuguese documents extracted from the Arquivo Nacional da Torre do Tombo.

CIDOC-CRM Ontology Representation of the Portuguese Archival Description Unit Obtained From the Semantic Migration Process of DigitArq

This dataset includes CIDOC-CRM Ontology Representations of DigitArq records.

Discourse Ontology for Incorporation/Transference Events

The Discourse Ontology for Incorporation/Transference Events is an OWL ontology, a semantic interpretation ontology (SIO), that contains the concepts and relations used in natural language sentences describing these events. The ontology also contains a set of semantic web language rules (SWLR) to model dates.

ISAD(G) Descriptions of Archival Records With Entity Annotation

This dataset contains long text ISAD(G) fields from the Arquivo Nacional da Torre do Tombo’s records annotated with entities. It was built to evaluate the effectiveness of data migration from ISAD(G) to ArchOnto in the EPISA project.

Analysis of the DigitArq archive record entities and their properties in Wikidata and in DBpedia

This dataset is the result of a master’s dissertation which analyzed a sample of 25 records from the Portuguese National Archives, chosen by archival specialists as representative of different fonds and description levels, to identify entities and properties and explore relationships with other non-archival resources.

User evaluation of the DigitArq and DigitArq+ interfaces

This dataset was generated in an experiment with two groups of users (common users and archivists) of both of the DigitArq platform interface and DigitArq+, a new interface developed in the EPISA project. A script with different questions was developed to evaluate the quality of access and search behavior.

Analysis of baptism, marriage and death registers belonging to the District Archives of Guarda, the District Archives of Porto and deferred passports from the District Archives of Bragança

This dataset has description units related to baptisms, marriages and deaths from the District Archive of Guarda; baptisms, marriages and deaths from the District Archive of Porto; and, finally, deferred passports from the District Archive of Bragança.

Consensual ArchOnto representation of 13 Portuguese Historical Archival Records based on their Digital Representations

The dataset contains archival descriptions represented in the ArchOnto model of 13 records from the 20th century with typewritten digital representations. We selected a sample of 13 records from a previously developed dataset that extracted typewritten digital representations from the Arquivo Nacional da Torre do Tombo. Afterwards, two archivists from Direção-Geral do Livro, dos Arquivos e das Bibliotecas (DGLAB) performed the descriptions, and upon discussion, we reached a consensual description.

ArchOnto ontology representation of Portuguese archival description units (baptism records and passports)

The dataset contains archival descriptions represented in the ArchOnto ontology of DigitArq baptisms records and passports. It also contains the ArchOnto Ontology version used and its sub-ontologies (CIDOC-CRM, N-ary, DataObject, Link2DataObject, and ISAD Ontology).
