A lookup index for Semantic Web resources

Eyal Oren, Giovanni Tummarello
2007 Extended Semantic Web Conference  
For developers of Semantic Web applications, which operate on Semantic Web data, the decentralisation poses a challenge: how and where to find statements (information) about certain resources?  ...  A simple lookup index We have developed (an initial version of) a simple lookup index called Sindice that helps developers in this situation.  ...

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  
We present Sindice, a lookup index over resources crawled on the Semantic Web. Our index allows applications to automatically locate documents containing information about a given resource.  ...  Developers of Semantic Web applications face a challenge with respect to the decentralised publication model: how and where to find statements about encountered resources.  ...  To predict the project index size for indexing such resources, we have crawled Semantic Web data for around four weeks and collected some 3.2 million unique resources.  ...

A Peer-to-Peer Architecture to Enable Versatile Lookup System Design

V. Sawant, J. Kaur
2006 22nd International Conference on Data Engineering Workshops (ICDEW'06)  
The resource lookup requirements in applications such as web caching, web content search, content distribution, resource sharing, network monitoring and management, and e-commerce have caught the attention  ...  In this paper, we present an architecture for P2P systems that identifies the functions necessary for designing resource lookup systems with wide applicability.  ...  A P2P lookup system based on HYROAD can use semantic association as a criterion for neighbor selection, to improve entity-partitioned index based lookups.  ...

An Ontological Framework for Large-Scale Grid Resource Discovery

Juan Li, Son Vuong
2007 Proceedings of the IEEE Symposium on Computers and Communications  
Inside communities, resource knowledge is integrated between nodes, and a DHT overlay is used for knowledge dissemination and discovery.  ...  to expand semantic knowledge of shared grid resources.  ...  In the last few years, several projects aimed to combine the strengths of grid and semantic web technologies, particularly for the use of resource sharing.  ...

Enhancing the Discoverability and Interoperability of Multi-Disciplinary Semantic Repositories

Doron Goldfarb, Yann Le Franc
2017 International Semantic Web Conference  
In this context, we argue that there is a need for a semantic lookup-service to access and use this heterogeneous landscape.  ...  These semantic resources are often hosted within domain specific repositories which can be harvested for that purpose.  ...  Magagna for her invaluable contribution, S. Cox and the RDA Vocabulary Service Interest Group for their interest and support.  ...

SPiDeR: P2P-Based Web Service Discovery [chapter]

Ozgur D. Sahin, Cagdas E. Gerede, Divyakant Agrawal, Amr El Abbadi, Oscar Ibarra, Jianwen Su
2005 Lecture Notes in Computer Science  
In this paper, we describe SPiDeR, a peer-to-peer (P2P) based framework that supports a variety of Web service discovery operations.  ...  SPiDeR organizes the service providers into a structured P2P overlay and allows them to advertise and lookup services in a completely decentralized and dynamic manner.  ...  For example, a peer might choose to keep each list as a sequential file, which might not be very efficient. More efficient index lookups can be achieved by using more efficient indexing schemes.  ...

HPRD: A High Performance RDF Database [chapter]

Liu Baolin, Hu Bo
2007 Lecture Notes in Computer Science  
In this paper a high performance storage system for RDF documents is introduced. The system employs optimized index structures for RDF data and efficient RDF query evaluation.  ...  Path index manages frequent RDF path patterns for long path query performance enhancement. Context index is optional for context oriented RDF data and temporal RDF data.  ...  In Semantic Web, by using metadata to describe the resources, it is possible to perform more intelligent machine-to-machine interactions, such as reasoning, deduction and semantic searches.  ...

2011 Lecture Notes in Computer Science  
Finally, we also introduce three Web access entries namely SPARQL endpoint, lookup interface and detailed data view, which conform to the principles of publishing data sources to LOD.  ...  While DBpedia, one of the LOD core data sources, contains resources described in multilingual versions and semantic data in English is proliferating, there is very few work on publishing Chinese semantic  ...  Lookup Service For users who do not know the exact IRI of a given resource name, we provide a lookup service to help them.
