HSLD: a hybrid similarity measure for linked data resources

Gabriela Oliveira Mota Da Silva, Paulo Roberto De Souza, Frederico Araújo Dur�ã, N.A. o
2020 International Journal of Metadata, Semantics and Ontologies  
Such a huge amount of data available along with the development of semantic web standards has opened up opportunities for the development of semantic applications.  ...  In this paper we propose HSLD, a hybrid similarity measure for Linked Data that exploits information present in RDF literals besides the links between resources.  ...  Introduction While the World Wide Web has provided means for creating a web of human readable documents, the Web of Data (also referred as Linked Data) has created paths for a web of structured and machine-readable  ...

LOTUS: Linked Open Text UnleaShed

Filip Ilievski, Wouter Beek, Marieke van Erp, Laurens Rietveld, Stefan Schlobach
2015 International Semantic Web Conference  
It is difficult to find resources on the Semantic Web today, in particular if one wants to search for resources based on natural language keywords and across multiple datasets.  ...  The SPARQL query language is largely oriented towards matching graph patterns and datatyped values.  ...  Semantically speaking, RDF literals denote resources, similar to the way in which IRIs denote resources.  ...

Moving from syntactic to semantic organizations using JXML2OWL

Toni Rodrigues, Pedro Rosa, Jorge Cardoso
2008 Computers in industry (Print)  
Emerging Semantic Web technologies, such as ontologies, RDF, RDFS, and OWL, can play an important role in the semantic definition and integration of data.  ...  The framework supports mappings and fully automated instance transformation from syntactic data sources in XML format to a common shared global model defined by an ontology using Semantic Web technologies  ...  Toward this objective, several standards have emerged under the initiative of the W3C, such as RDF, RDFS and OWL.  ...

Semantic Similarity from Natural Language and Ontology Analysis

Sébastien Harispe, Sylvie Ranwez, Stefan Janaqi, Jacky Montmain

E-Assessment Data Compatibility Resolution Methodology with Bidirectional Data Transformation

2017 Eurasia Journal of Mathematics, Science and Technology Education  
This can be done with the use of Semantic Web data model Resource Description Framework (RDF) built-up using hierarchal and linked data representation.  ...  These data forms are essential to be converted into semantical annotated form to support Artificial Intelligence.  ...  Unorganized to Organized Web Using Semantic Web Semantic Web introduced RDF as a data model having capability of capturing hierarchal relationship among different resources (Musen, 2015) .  ...

Bringing relational databases into the Semantic Web: A survey

2012 Semantic Web Journal  
Ontologies, on the other hand, are one of the key concepts and main vehicle of knowledge in the Semantic Web research area.  ...  Web.  ...  Initially, the need for mapping databases to ontologies arose from the necessity to semantically annotate Web pages in order to facilitate the "upgrade" of the cur-rent Web of documents to a Web of data  ...

Towards a Fully Generic Theory of Data [chapter]

Semantic Web enabled digital repositories

Dimitrios A. Koutsomitropoulos, Georgia D. Solomou, Andreas D. Alexopoulos, Theodore S. Papatheodorou
2009 International Journal on Digital Libraries  
To this end, in this article we propose a method and a practical implementation that could allow traditional metadata-intensive repositories to benefit from Semantic Web ideas and techniques.  ...  Digital repositories and digital libraries are today among the most common tools for managing and disseminating digital object collections of cultural, educational, and other kinds of content over the Web  ...  These documents virtually suggest an ontology of DC, expressed in RDF(S), a Semantic Web standard.  ...

Music domain ontology applications for intelligent web searching

Maria Clara Valles, Pablo Fillottrani
2009 Ciencia y Tecnología  
Three important technologies for developing the Semantic Web are already in place: Extensible Markup Language (XML), the Resource Description Framework (RDF), and Web Ontology Language (OWL).  ...  The Semantic Web is an extension of the current Web that attempts to reach a state in the future where everything on the Web will no longer be only machine-readable, but also machine-understandable.  ...  The first steps towards incorporating the Semantic Web into the structure of the existing Web are already under way.  ...

Supporting Arbitrary Custom Datatypes in RDF and SPARQL [chapter]

Maxime Lefrançois, Antoine Zimmermann
2016 Lecture Notes in Computer Science  
Custom datatypes have reported use on the Web of Data, and show some advantages in representing some classical structures. Yet, their support by RDF processors is rare and implementation specific.  ...  Based on this, we discuss solutions that would enable: (i) data publishers to publish the definition of arbitrary custom datatypes on the Web, and (ii) generic RDF processor or SPARQL query engine to discover  ...  To make this clear, consider a datatype where the lexical space is the set of Turtle documents, and the value space contains the equivalent classes of RDF graphs according to the OWL 2 RDF-based semantics  ...

2015 International Conference on Dublin Core and Metadata Applications  
In the context of the DCMI RDF Application Profile task group and the W3C Data Shapes Working Group solutions for the proper formulation of constraints and validation of RDF data on these constraints are  ...  We are using this collection of constraint types to gain a better understanding of the expressiveness of existing solutions and gaps that still need to be filled.  ...  In general, RDF documents follow the syntactic structure and the semantics of RDFS/OWL ontologies which could therefore not only be used for reasoning but also for validation.  ...
