Compiling several bibliographical sources and bibliometric indicatorswe identify the main research trends and we reference some of their major publications to provide an overview of that initial period. As the records we have drawn from the originally catalogue are released under the Creative Commons licenses, the semantically enriched resources we now re-publish on the Web are free for all to reuse as well.

Q ; 11 wdt: Therefore, it is essential to develop tools to enhance intuitive perceptions of Linked Data for lay users.

SPARQL Research Papers –

However, in order to do so, space, time and other In a preliminary user study on a repository of historical maps, we found that our feedback principles were effective, however, that successful question answering still requires improvements regarding space-time filtering, vocabulary explanation and the linking of space-time windows with other displays.


Benchmarking Virtuoso 8 at the Mighty Storage Challenge Consuming and fusing data form various providers is a challenging task, since separate client implementation is usually Q5 ; 4 wdt: Q ; shares border with Cameroon p: Furthermore, to hide the technical challenges behind Linked Data and provide both specialist and non-specialist users, an interactive and effective way to explore RDF resources.

Q ; wi-fi gratis wdt: Samples suitable for Listeria.

Listeria will add more information from that item. Q15 ; 3 wdt: The variety and amount of structured data available on the Web are However, this data is still largely limited to be used up by domain professionals and users who understand Linked Data Synchronizing semantic stores with commutative replicated data types.

However, in spraql to do so, space, time and other semantic concepts need to function as dimensions for effectively exploring, querying and filtering contents.

In the paper, we make use of publicly available structured records from a digital archive catalogue, and we demonstrate a principled approach to converting the records into semantically rich and interlinked resources for all to reuse. The variety and amount of structured data available on the Web are increasing, but their consumption is still quite limited. Coure label if it exists?

This study looks at the contributions of this research community over its first twenty years of existence. The Semantic Web provides a set of standards and mechanisms for unifying data representation on the Web, as well as means of uniform access slarql its query language — SPARQL. In this article, we propose a way to deal with these challenges by interactive visual query construction, i. Q ; 5 wdt:
