Apache Jena - Welcome to JenaJena is a Java framework for building Semantic Web applications. Jena provides a collection of tools and Java libraries to help you to develop semantic web and linked-data apps, tools and servers.
An Enhanced Indexing And Ranking Technique On The Semantic WebWith the fast growth of the Internet, more and more information is available on the Web. The Semantic Web has many features which cannot be handled by using the traditional search engines. It extracts metadata for each discovered Web documents in RDF or OWL formats, and computes relations between documents. We proposed a hybrid indexing and ranking technique for the Semantic Web which finds relevant documents and computes the similarity among a set of documents. First, it returns with the most related document from the repository of Semantic Web Documents (SWDs) by using a modified version of the ObjectRank technique. Then, it creates a sub-graph for the most related SWDs. Finally, It returns the hubs and authorities of these document by using the HITS algorithm. Our technique increases the quality of the results and decreases the execution time of processing the user's query.Ahmed Tolba, Nabila Eladawi, Mohammed Elmogy
SDoW2011, 4th international workshop on Social Data on the Web, co-located with the 10th International Semantic Web Conference (ISWC2011)The 4th international workshop Social Data on the Web (SDoW2011), co-located with the 10th International Semantic Web Conference (ISWC2011) , aims to bring together researchers, developers and practitioners involved in semantically-enhancing social media websites, as well as academics researching more formal aspect of these interactions between the Semantic Web and Social Web.
Semantic Web ArchitectureThe Semantic Web extends the existing Web, adding a multitude of language standards and software components to give humans and machines direct access to data. The chapter starts with deriving the architecture of the Semantic Web as a whole from first principles,
followed by a presentation of Web standards underpinning the Semantic Web that are used for data publishing, querying and reasoning. Further, the chapter identifies functional software components required to implement capabilities and behaviour in applications that publish
and consume Semantic Web content.Andreas Harth, Maciej Janik, Steffen Staab

RDF Working Group CharterThe mission of the RDF Working Group, part of the Semantic Web Activity, is to update the 2004 version of the Resource Description Framework (RDF) Recommendation. The scope of work is to extend RDF to include some of the features that the community has identified as both desirable and important for interoperability based on experience with the 2004 version of the standard, but without having a negative effect on existing deployment efforts.W3C

A Direct Mapping of Relational Data to RDFThe need to share data with collaborators motivates custodians and users of relational databases (RDB) to expose relational data on the Web of Data. This document defines a direct mapping from relational data to RDF. This definition provides extension points for refinements within and outside of this document.

The History of Information, by David Siegel on VimeoDavid Siegel, author of 4 books about the web, presents his new 8-minute video on the history and future of information. Using a fast pace and fun graphics, Siegel introduces us to the next wave of innovation with two key concepts he claims will affect $10 trillion of commerce worldwide: pull and the semantic web. This concise introduction to the wider concepts of his new book on the topic, Pull, will guide you in making the shift from push to pull. Caution: this video will make you think about potential changes you might want to make to your business model and the way you do business.

RDFa PrimerToday's web is built predominantly for human consumption. Even as machine-readable data begins to appear on the web, it is typically distributed in a separate file, with a separate format, and very limited correspondence between the human and machine versions. As a result, web browsers can provide only minimal assistance to humans in parsing and processing web data: browsers only see presentation information. We introduce RDFa, which provides a set of XHTML attributes to augment visual data with machine-readable hints. We show how to express simple and more complex datasets using RDFa, and in particular how to turn the existing human-visible text and links into machine-readable data without repeating content.W3C
W3C RDFa Working GroupThe mission of the RDFa Working Group, part of the Semantic Web Activity is to support the developing use of RDFa for embedding structured data in Web documents in general. The Working Group will publish W3C Recommendations to extend and enhance the currently published RDFa 1.0 documents, including an API. The Working Group will also support the HTML Working Group in its work on incorporating RDFa in HTML5 and XHTML5.
LOD cloud shows surprisingly lumpy structureThe protypical Linked Open Data map gives the general impression of a richly interlinked set of bubbles.However, A small experiment showed that this first impression is very wrong!
RDFa in XHTML: Syntax and Processing 1.1RDFa is a specification for attributes to express structured data in any markup language. This document specifies how to use RDFa with XHTML. The rendered, hypertext data of XHTML is reused by the RDFa markup, so that publishers don't need to repeat significant data in the document content. The underlying abstract representation is RDF [RDF-PRIMER], which lets publishers build their own vocabulary, extend others, and evolve their vocabulary with maximal interoperability over time. The expressed structure is closely tied to the data, so that rendered data can be copied and pasted along with its relevant structure.RDFa Working Group
RDFa Working Group WikiThe mission of the RDFa Working Group, part of the Semantic Web Activity is to support the developing use of RDFa for embedding structured data in Web documents in general. The Working Group will publish W3C Recommendations to extend and enhance the currently published RDFa 1.0 documents, including an API. The Working Group will also support the HTML Working Group in its work on incorporating RDFa in HTML5 and XHTML5. This Wiki is the main working area of the Working Group, that has started its work in February 2010.
This Wiki is public, meaning that all pages can be read by the general public. However, only members of the Working Group have the authorization to edit these pages. RDFa Working Group

www.semantic-web-journal.nethe journal Semantic Web – Interoperability, Usability, Applicability brings together researchers from various fields which share the vision and need for more effective and meaningful ways to share information across agents and services on the future internet and elsewhere. As such, Semantic Web technologies shall support the seamless integration of data, on-the-fly composition and interoperation of Web services, as well as more intuitive search engines. The semantics – or meaning – of information, however, cannot be defined without a context, which makes personalization, trust, and provenance core topics for Semantic Web research. New retrieval paradigms, user interfaces, and visualization techniques have to unleash the power of the Semantic Web and at the same time hide its complexity from the user. Based on this vision, the journal welcome contributions ranging from theoretical and foundational research over methods and tools to descriptions of concrete ontologies and applications in all areas. We especially welcome papers which add a social, spatial, and temporal dimension to Semantic Web research, as well as application-oriented papers making use of formal semantics.
The journal is peer-reviewed and will be published quarterly.
