Valid Time RDF
… of Resource Description Framework (RDF) and Web Ontology Language (OWL) do not include constructs for handling time-varying data and knowledge. For simplicity, RDF model is confined to binary predicates, hence some form of reification is needed to represent higher-arity predicates. …

RDF-muotoisen datan tietokantaratkaisut
… standardeihin sitoutuminen korostuu. RDF on standardoitu tietomalli, joka voi toimia linkkinä heterogeenisten tietovarastojen välillä. RDF-muotoisen datan määrä onkin kasvanut viime vuosina voimakkaasti, mikä korostaa tehokkaiden ja skaalautuvien talletusratkaisujen tärkeyttä. Tässä …

Improving RDF data with data mining
… Those datasets are mostly presented in the RDF triple structure of subject, predicate, and object, where each triple represents a statement or fact. Unfortunately, the heterogeneity of available open data requires significant integration steps before it can be used in applications. Meta …

LSPARQL: Transaction Time Queries in RDF
The Resource Description Framework (RDF) is a general framework for the standardised interchange of information over the semantic web by way of RDF triples. Specifying temporal information which describes when individual triples hold using standard RDF is convoluted, and temporal query evaluation …

Semi-automatic extraction of RDF triples from Wikipedia tables
Wikipedia es una enciclopedia en línea, multilingüe y gratuita disponible en 339 ediciones. La edición de Wikipedia en inglés actualmente cuenta con más de 6,7 millones de artículos y 46 millones de usuarios registrados. Una gran cantidad de información en Wikipedia se encuentra contenida en …

Foundations of Regular Languages for Processing RDF and XML
… (XML) und das Resource Description Framework (RDF). Wir werden uns zunächst mit der Komplexität von regulären Sprachen in dem Kontext XML und RDF beschäftigen. Danach untersuchen wir die Auswertung von dynamischen Daten, die aus heutiger Sicht immer relevanter für die web-basiere …

Using low latency storage to improve RDF store performance
Resource Description Framework (RDF) is a flexible, increasingly popular data model that allows for simple representation of arbitrarily structured information. This flexibility allows it to act as an effective underlying data model for the growing Semantic Web. Unfortunately, it remains a …

Identifying, Relating, Consisting and Querying Large Heterogeneous RDF Sources
… datasets from a huge heterogeneous collection of RDF (Resource Description Framework) datasets. To address this issue, we need to assure the consistency and to know how the datasets are related and how similar they are. As results, to deal with the need for identifying LOD (Linked Open Data) …

A scalable analysis framework for large-scale RDF data
… growth of the Semantic Web, the availability of RDF datasets from multiple domains as Linked Data has taken the corpora of this web to a terabyte-scale, and challenges modern knowledge storage and discovery techniques. Research and engineering on RDF data management systems is a very active area …

The Morpheus Visualization System : a general-purpose RDF results browser
As the amount of information available on the deep web grows, finding ways to make this information accessible is growing increasingly problematic. As some have estimated that the content in the deep web is several orders of magnitude greater than that in the shallow web, there is a clear need for …

Distributed RDF query processing and reasoning for big data / linked data
… This is based on Resource Description Framework (RDF) that represents the semantic data and a collection of such statements shapes an RDF graph. SPARQL is a query language designed specifically to query RDF data. Linked Data faces the same challenge that Big Data does. We now lead the way to a new …

Ontology-Based Extraction of RDF Data from the World Wide Web
The simplicity and proliferation of the World Wide Web (WWW) has taken the availability of information to an unprecedented level. The next generation of the Web, the Semantic Web, seeks to make information more usable by machines by introducing a more rigorous structure based on ontologies. One …

A New Approach for Fast Processing of SPARQL Queries on RDF Quadruples
The Resource Description Framework (RDF) is a standard model for representing data on the Web. It enables the interchange and machine processing of data by considering its semantics. While RDF was first proposed with the vision of enabling the Semantic Web, it has now become popular in …

A BIM - GIS Integrated Information Model Using Semantic Web and RDF Graph Databases
… and Resources Description Framework (RDF) graph databases. The suggested solution's originality and novelty come from combining the advantages of integrating BIM and GIS models into a semantically unified data model using a semantic framework and ontology engineering approaches. The …

Uma Avaliação de abordagens alternativas para armazenar RDF em banco de dados relacional
O Resource Description Framework (RDF) é uma infra-estrutura, que possibilita a codificação, troca e reuso de metadata estruturado. Metadata é dados sobre dados. O termo refere a qualquer dado usado para ajudar a identificação, descrição e localização de recursos eletrônicos na rede. O RDF permite …

Query Answering over Contextualized RDF/OWL Knowledge with Expressive Bridge Rules: Decidable classes
In this thesis, we study the problem of reasoning and query answering over contextualized knowledge in quad format augmented with expressive forall-existential bridge rules. Such bridge rules contain conjunctions, existentially quantified variables in the head, and are strictly more expressive than …

A study of graph partitioning techniques for fast indexing and query processing of a large RDF graph
… years, the Resource Description Framework (RDF) [34] has become increasingly important for the Web and in domains such as defense and healthcare. Companies such as the New York Times [40], Best Buy [39], and Pfizer are leveraging RDF and other Semantic Web technologies for data management. …

Parallel SPARQL Query Execution using Apache Spark
… such as Resource Description Framework (RDF) and SPARQL are increasingly being adopted by applications on the Web, as well as in domains such as healthcare, finance, and national security and intelligence. While we have witnessed an era of many different techniques for RDF indexing and …

Improving the Performance of Parallel SPARQL Query Processing on Apache Spark Using Bloom Filters
The Resource Description Framework (RDF) has become the standard model for data representation on the Web. In RDF, IRIs are used to represent entities and their relationships. SPARQL is the query language for RDF. Today, popular knowledge bases on the Web (e.g., Wikidata, YAGO, Linked Data) employ …
