, 2020 The growth experienced by the internet in the past few years as lead to an increased amount of available data and knowledge obtained from said data. However most of this knowledge is lost due to the lack of associated semantics making the task of interpreting data very hard to computers.

NITELIGHT: A Graphical Tool for Semantic Query Construction
, 2008 Query formulation is a key aspect of information retrieval, contributing to both the efficiency and usability of many semantic applications. A number of query languages, such as SPARQL, have been developed for the Semantic Web; however, there are, as yet,

A Novel Digitalization Approach for Smart Materials – Ontology‐Based Access to Data and Models
Advanced Engineering Materials, Volume 27, Issue 8, April 2025.In order to access heterogeneous material data and model‐based knowledge, the established ontology‐based data access (OBDA) is extended to include material models. This novel ontology‐based data and model access (OBDMA) enables the computation of new responses beyond stored data.

Sparql-Ld: A Sparql Extension For Fetching And Querying Linked Data
Proceesings of the 14th International Semantic Web Conference - Demonstrations Track (ISWC'15), 2015 SPARQL is a standard query language for retrieving and manipulating RDF data. However, the majority of SPARQL implementations require the data to be available in advance, i.e., to exist in main memory or in a RDF repository (accessible through a SPARQL endpoint).

International Journal of Approximate ReasoningDuring the last years, the study of fuzzy database query languages has attracted the attention of many researchers. In this line of research, our group has proposed and developed FSA-SPARQL (Fuzzy Sets and Aggregators based SPARQL), which is a fuzzy extension of the Semantic Web query language SPARQL. FSA-SPARQL works with fuzzy RDF datasets and allows

Pemanfaatan Linked Data untuk Meningkatkan Kualitas Information Knowledge pada Resources Game Online
Jurnal Nasional Teknik Elektro dan Teknologi Informasi, 2017 This paper proposes an online game design that has resources with interoperability. Interoperability means the resources can share, re-used, and interlinked with another Unified Resources Identifier (URI).

Proceedings of the 22nd international conference on World Wide Web, 2013 Over the past years, Semantic Web and Linked Data technologies have reached the backend of a considerable number of applications. Consequently, large amounts of RDF data are constantly being made available across the planet. While experts can easily gather information from this wealth of data by using the W3C standard query language SPARQL, most lay ...
