This research is conducted on the scope of Digital Humanities, and it aims to reinforce the alliance between the areas of information science and computer science, applying it into an ethnomusicological context. Ethnomusicological researchers work on many types of audio-visual data, such as photos, videos, music, and sound recordings. The needs involved in the use and dissemination of such kind of data can be problematic, given their diverse formats, sources, and the increasing quantity of data and technologies involved in their production and study. So, in this environment, new exchange of experiences has taken place between computer science and information science researchers for the development of a knowledge framework able to deal with such amount of available audio-visual data. However, despite the recent advances, the ethnomusicologic field is still missing uniform metadata, ontologies, and taxonomies, complicating data interoperability and reusability. This article discusses the initial results obtained within the scope of the INET-md – the Institute of Ethnomusicology – Centre for Studies in Music and Dance, in Portugal, and presents the remaining challenges. Semantic is undoubtedly the “answer” to face many of these obstacles. published

In 2022, the University of Aveiro started the implementation of DUnAs, an open repository for archiving and publishing data that supports scientific research at the University of Aveiro, Portugal. This abstract presents an experience with DUnAS, through a pilot research project from INET-md research center. The project, called SOMA - Sounds and Memories of Aveiro, belongs to the field of Ethnomusicology and deals with audiovisual data. In Ethnomusicology, researchers often work with multiple types of multimedia documents such as photos, videos, sounds, and music recordings. The need to preserve and easily access, visualize, and annotate such materials can be problematic and challenging. Some of the “obstacles” faced in the implementation of this repository, in an ethnomusicological context, are presented and some important questions are posed. published

In the context of the Semantic Web, a domain ontology may be used to provide the necessary support for linking together a large number of heterogeneous data sources pertaining to a same domain. In this paper, such data sources are ?rst described as local ontologies. Then, each local ontology is rewritten as an application ontology, whose vocabulary is restricted to be a subset of the vocabulary of the domain ontology. Application ontologies enable the identi?cation and the association of semantically corresponding concepts, and thereby help information discovery and retrieval, and also data integration. The main contribution of this paper is a strategy to automatically generate application ontologies, considering a set of local ontologies, a domain ontology and the result of the matching between each local ontology and the domain ontology. The proposed strategy also enables the automatic generation of mappings between the domain ontology and the application ontologies, and between each application ontology and its corresponding local ontology, which are used to query the data sources through the domain ontology.

This article concerns the path taken during my scientific research related to the construction and management of digital assets for the design, development, and management of databases, within the scope of the INET-md in Portugal. Its general objective is to facilitate the interoperability, Web dissemination, search, and retrieval of the INET-md's digital collections. This investigation aims to reinforce the alliance between the areas of Information Science and Computer Science. From the Information Science, it brings the applications used for organization, management, and publication of digital assets collections on the Web; and from the Computer Science, it brings syntactic concepts (metadata and protocols) to communicate and exchange data and semantic concepts (ontologies and semantic annotations) to describe data. Both types of concepts can promote interoperability between distinct digital repositories and platforms, providing improvements in information search and retrieval activities. Este artigo diz respeito ao caminho percorrido durante a minha investigação científica relacionada à construção e gestão de ativos digitais para a conceção, desenvolvimento e gestão de bases de dados, no âmbito do INET-md em Portugal. Seu objetivo geral é facilitar a interoperabilidade, disseminação na Web, busca e recuperação das coleções digitais do INET-md. Esta investigação visa reforçar a aliança entre as áreas de Ciência da Informação e Ciência da Computação. Da Ciência da Informação, traz os aplicativos utilizados para organização, gestão e publicação de acervos de ativos digitais na Web; e da Ciência da Computação, traz conceitos sintáticos (metadados e protocolos) para comunicar e trocar dados e conceitos semânticos (ontologias e anotações semânticas) para descrever dados. Ambos os tipos de conceitos podem promover a interoperabilidade entre distintos repositórios e plataformas digitais, proporcionando melhorias nas atividades de busca e recuperação de informações. published
