Aidan Hogan, Andreas Harth, JJrgen Umbrich, Sheila Kinsella, Axel Polleres, Stefan Decker
2011 Social Science Research Network  
, SWSE operates over RDF Web dataloosely also known as Linked Data -which implies unique challenges for the system design, architecture, algorithms, implementation and user interface.  ...  In this paper, we discuss the architecture and implementation of the Semantic Web Search Engine (SWSE).  ...  We could investigate inclusion of a livelookup component in SWSE for a subset of queries which we identify to be best answered by means of live lookup; however, further research in this area is required  ...

Querying and Searching Heterogeneous Knowledge Graphs in Real-time Linked Dataspaces [chapter]

André Freitas, Seán O'Riáin, Edward Curry
2019 Real-time Linked Dataspaces  
This chapter investigates the main challenges in constructing query and search services for knowledge graphs within a linked dataspace.  ...  Search and query services within a linked dataspace do not follow a one-size-fits-all approach and utilise a range of different techniques to support different characteristics of data sources and user  ...  The information that can answer this query may be available in the linked dataspace.  ...

Sindice.com: Weaving the Open Linked Data [chapter]

Giovanni Tummarello, Renaud Delbru, Eyal Oren
2007 Lecture Notes in Computer Science  
The "linked data" approach, which mandates that resource URIs should be de-referenced and yield metadata about the resource, helps but is only a partial solution.  ...  Feasability Before detailing the internals of Sindice, we analyse its feasibility.  ...  and on the other hand Semantic Web (SW) search engines such as SWSE or Swoogle.  ...

Querying Heterogeneous Datasets on the Linked Data Web: Challenges, Approaches, and Trends

Andre Freitas, Edward Curry, Joao Gabriel Oliveira, Sean O'Riain
2012 IEEE Internet Computing  
The information that can answer this query is already available on the Web as linked data.  ...  To query linked data on the Web today, users must first be aware of which exposed datasets potentially contain the data they want and what data model describes these datasets, before using this information  ...

Linked Data Indexing Methods: A Survey [chapter]

Martin Svoboda, Irena Mlýnková
2011 Lecture Notes in Computer Science  
Despite the research effort in recent years, several questions in the area of Linked Data indexing and querying remain open, not only since the amount of Linked Data globally available significantly increases  ...  The concept of Linked Data based primarily on RDF data triples seems to successfully solve this drawback.  ...  SWSE. The purpose of SWSE by Harth et al. [10] is to provide a system for global searching over quads (RDF triples with their context).  ...

Browsing Linked Data Catalogs with LODAtlas [chapter]

Emmanuel Pietriga, Hande Gözükan, Caroline Appert, Marie Destandau, Šejla Čebirić, François Goasdoué, Ioana Manolescu
2018 Lecture Notes in Computer Science  
The Web of Data is growing fast, as exemplified by the evolution of the Linked Open Data (LOD) cloud over the last ten years.  ...  Data analysts, data journalists and other enduser profiles can find the various datasets, ideally already linked, that will help them answer their questions.  ...  a much more human-friendly manner (SWSE); and providing useful metadata about the source (Watson).  ...

Sindice.com: a document-oriented lookup index for open linked data

Eyal Oren, Renaud Delbru, Michele Catasta, Richard Cyganiak, Holger Stenzhorn, Giovanni Tummarello
2008 International Journal of Metadata, Semantics and Ontologies  
The "linked data" approach mandates that resource URIs should be de-referenced to return resource metadata.  ...  As mentioned before, we have not yet explored this possibility.  ...  and on the other hand Semantic Web (SW) search engines such as SWSE or Swoogle.  ...

RDFS and OWL Reasoning for Linked Data [chapter]

Axel Polleres, Aidan Hogan, Renaud Delbru, Jürgen Umbrich
2013 Lecture Notes in Computer Science  
Linked Data promises that a large portion of Web Data will be usable as one big interlinked RDF database against which structured queries can be answered.  ...  In this lecture we will show how reasoningusing RDF Schema (RDFS) and the Web Ontology Language (OWL)can help to obtain more complete answers for such queries over Linked Data.  ...  Data-warehousing approaches for querying linked data are typically deployed for RDF search engines such as Sindice [54] or SWSE [40] .  ...

SAOR: Template Rule Optimisations for Distributed Reasoning over 1 Billion Linked Data Triples [chapter]

Aidan Hogan, Jeff Z. Pan, Axel Polleres, Stefan Decker
2010 Lecture Notes in Computer Science  
We evaluate our methods using LUBM(10) for RDFS, pD* (OWL Horst) and OWL 2 RL, and thereafter demonstrate pragmatic distributed reasoning over 1.12 billion Linked Data statements for a subset of OWL 2  ...  Reasoning for Linked Data Again, we aim at reasoning over Linked Data for the SWSE project.  ...  Given our use-case SWSE, we wish to infer a circumspect amount of data with utility for query-answering -completeness is not a requirement (cf. [5] for related discussion).  ...

Summary Models for Routing Keywords to Linked Data Sources [chapter]

Thanh Tran, Lei Zhang, Rudi Studer
2010 Lecture Notes in Computer Science  
The proliferation of linked data on the Web paves the way to a new generation of applications that exploit heterogeneous data from different sources.  ...  As a solution, we present a family of summary models, which compactly represents the Web of linked data and allows to quickly find relevant sources.  ...  It helps users without knowledge of the evolving linked data and schema to find combination of sources that contain answers corresponding to their needs.  ...

Carlo Allocca, Mathieu d'Aquin, Enrico Motta
2012 Lecture Notes in Computer Science  
However, Ontology Search, as the activity of using a SWSE to find appropriate ontologies, has not been considered before from an user-centric point of view.  ...  They generally knew Watson, even if they had not extensively used it before (if at all, see Watson Exp) and some of them had some knowledge of other SWSEs (such as Swoogle and Sindice, see OtherSWSE ).  ...
