O surgimento de novas tecnologias, tem introduzido meios para a divulgação e a disponibilização das informações mais eficientemente. Uma iniciativa, chamada de Europeana, vem promovendo esta adaptação dos objetos informacionais dentro da Web, e mais especificamente no Linked Data. Desta forma, o presente estudo tem como objetivo apresentar uma discussão acerca da relação entre as Humanidades Digitais e o Linked Open Data, na figura da Europeana. Para tal, utilizamos uma metodologia exploratória e que busca explorar as questões relacionadas ao modelo de dados da Europeana, EDM, por meio do SPARQL. Como resultados, compreendemos as características do EDM, pela utilização do SPARQL. Identificamos, ainda, a importância que o conceito de Humanidades Digitais possui dentro do contexto da Europeana.Palavras-chave: Web semântica. Linked open data. Humanidades digitais. Europeana.

Query Performance

Semantic Web has recently gained traction with the use of Linked Open Data (LOD) on the Web. Although numerous state-of-the-art methodologies, standards, and technologies are applicable to the LOD cloud, many issues persist. Because the LOD cloud is based on graph-based resource description framework (RDF) triples and the SPARQL query language, we cannot directly adopt traditional techniques employed for database management systems or distributed computing systems. This paper addresses how the LOD cloud can be efficiently organized, retrieved, and evaluated. We propose a novel hybrid approach that combines the index and live exploration approaches for improved LOD join query performance. Using a two-step index structure combining a disk-based 3D R*-tree with the extended multidimensional histogram and flash memory-based k-d trees, we can efficiently discover interlinked data distributed across multiple resources. Because this method rapidly prunes numerous false hits, the performance of join query processing is remarkably improved. We also propose a hot-cold segment identification algorithm to identify regions of high interest. The proposed method is compared with existing popular methods on real RDF datasets. Results indicate that our method outperforms the existing methods because it can quickly obtain target results by reducing unnecessary data scanning and reduce the amount of main memory required to load filtering results.

This paper discusses issues that will affect the future development of the Web, either increasing its power and utility, or alternatively suppressing its development. It argues for the importance of the continued development of the Linked Data Web, and describes the use of linked open data as an important component of that. Second, the paper defends the Web as a read–write medium, and goes on to consider how the read–write Linked Data Web could be achieved.

Представлен проект лингвистических связанных открытых данных (Linguistic Linked Open Data - LLOD), реализуемый международной рабочей группой на платформе Семантической сети. Излагаются принципы проекта, перечисляются принятые в нем стандарты и методики, рассматриваются главные ресурсы, загруженные в облако проекта в настоящее время. Обсуждаются основные понятия и приводится классификация языковых ресурсов, представленных в проекте. История проекта описывается через изложение материалов семинара участников LLOD в течение 2012-2020 гг. Приводятся проекты по развитию LLOD и преобразованию в него различных языковых ресурсов, которые выполняют исследовательские коллективы по всему миру. Делается вывод, что этот проект является наиболее перспективным направлением по интеграции и коллаборации в области языковых технологий и ресурсов.

Zusammenfassung Das Internationale Quellenlexikon der Musik (RISM) ist ein internationales Gemeinschaftsprojekt mit dem Ziel, die weltweit überlieferten Quellen zur Musik umfassend zu dokumentieren. Es bietet einen Online-Katalog, der Bibliothekaren, Musikern, Wissenschaftlern und allen interessierten Personen kostenlos zur Verfügung steht. Zunehmend gerät aber der Austausch von Daten in den Vordergrund, sei es von lokalen Online- Bibliothekskatalogen zu RISM oder umgekehrt. Für die Wissenschaft dürfte die Nachnutzung der Daten, die sowohl als Open Data als auch Linked Open Data bereitstehen, in Spezialprojekten von Interesse sein.
