OWL « TheSemanticBlog. The Oracle 11g platform offers a scalable, secure, robust platform for semantic web data management. Oracle 11g supports efficient management of RDF, OWL by executing simple queries. Data can be stored in the form of RDF triples and queried easily. Here are a series of steps to set up Semantic web support in Oracle 11g. 1. Install Oracle 11g and download the “JENADRV” patch from “ 2. Extract the JENADRV folder to some directory. 3. . - SQL>@Your_Drive_Name:\>Oracle_Home\product\11.0.1.0\md\admin\catsem10i.sql; This command restores Oracle 10 RDF data. 6.

Virtual Machine with RDF Semantic Graph New: 17-September-2013 This virtual machine includes all components of Oracle Spatial and Graph RDF Semantic Graph installed and configured with example code and data for ease of evaluation.
It also includes Oracle Business Intelligence Enterprise Edition that can be used with Oracle Spatial and Graph. Please see the license for details on included software. Please see the readme file for information about prerequisites, and installing and using this virtual box. Jena Adapter for Oracle Database Updated: 17-Oct-2013 The Jena Adapter for Oracle Database (Jena Adapter) provides a feature rich Java-based interface to RDF Semantic Graph that implements the well-known Jena Graph, Model, BulkUpdateHandler, and DatasetGraph APIs.
Release 12.1.0.1 Supports Apache Jena version 2.7.2, Joseki 3.4.4, JDK 1.6 or later and Oracle Database 11.2.0.3 or later. Documentation for Jena Adapter can be accessed in Chapter 7 of the Semantic Technologies Developer's Guide. RDF Primer. Tag: Owl - Tags - Semantic Focus - The Semantic Web, Semantic Web technology and computational semantics. Oracle Semantic Technologies Overview. This chapter describes the support for semantic technologies, specifically Resource Description Framework (RDF) and a subset of the Web Ontology Language (OWL). It assumes that you are familiar with the major concepts associated with RDF and OWL, such as {subject, predicate, object} triples, URIs, blank nodes, plain and typed literals, and ontologies. This chapter does not explain these concepts in detail, but focuses instead on how the concepts are implemented in Oracle.
For an excellent explanation of RDF concepts, see the World Wide Web Consortium (W3C) RDF Primer at information about OWL, see the OWL Web Ontology Language Reference at The PL/SQL subprograms for working with semantic data are in the SEM_APIS package, which is documented in Chapter 3. The RDF and OWL support are features of Oracle Spatial, which must be installed for these features to be used. This chapter contains the following major sections: Note: RDF Overview. This chapter describes the support for the Resource Description Framework (RDF) in the Oracle Spatial network data model. It assumes that you are familiar with the major concepts associated with RDF, such as reification, containers, and collections.
This chapter does not explain these concepts in detail, but focuses instead on how the concepts are implemented in the network data model. For an excellent explanation of RDF concepts, see the World Wide Web Consortium (W3C) RDF Primer at It is also helpful is you are familiar with the concepts and techniques of the network data model, as described in Oracle Spatial Topology and Network Data Models. The PL/SQL subprograms for working with RDF are in the SDO_RDF package, which is documented in Chapter 2, and in the SDO_RDF_INFERENCE package, which is documented in Chapter 3. 1.1 RDF and the Network Data Model RDF is a language used to describe metadata, particularly for information found on the Web. Semantic Web Strategies Conference (Fall 2007) The Semantic Web Strategies conference is coming to San Jose, CA September 30 to October 2, 2007.
The conference is being held by Jupitermedia and registration ranges from $50 for an exhibits-only pass and $1,795 for full conference options (if you register before the 12th of September you get a discount). The conference passport is the most expensive but you get the following good stuff: Pre-conference Tutorials: Sunday September 30, 1:00-5:00pm All Conference Sessions: October 1-2 Access to exhibit area in the ballroom foyer Conference Breakfasts, Lunches and Networking Events Conference Bag and take-home specialty items Access to online conference proceedings If you can't afford the conference passport, you may want to go after the one day pass which is priced at $795.
You won't get the pre-conference tutorials, but at least you're there. Speakers for the conference include: Eric Miller President, Zepheira LLC Nova Spivack CEO, Radar Networks Bob DuCharme Jans Aasman Melliyal Annamalai. Semantic Technologies Center.

Филатов В.А., Щербак С.С., Хайрова А.А Введение С расширением Internet работа поисковых систем все более усложнялась: чтобы обеспечить достаточный охват, им приходилось индексировать и обрабатывать все больший объем информации.
Но главная сложность заключалась даже не в увеличении количества индексируемых сайтов, а в том, чтобы обеспечить релевантные ответы на поисковые запросы пользователей, то есть выдавать пользователям ссылки на те ресурсы, которые, по их мнению, соответствуют тому, что они искали. Современное состояние дел в отдельных областях компьютерных наук диктует необходимость привлечения методов инженерии знаний для решения широкого класса практических задач. Ярким примером тому является инициатива Semantic Web, основная цель которой – наделить огромные массивы данных, опубликованных в сети Internet большей осмысленностью, повысить удобство работы с этой информацией. Существуют различные толкования самого понятия онтологии. В начало Актуальность и цель работы ‘(? Null, <rdf:RDF 1.
