SOBOLEO is a web-based system to help users share knowledge and experience more easily. Users collaboratively create a topic list and use this to tag people and web resources. This list is used as background knowledge during searches.

SOBOLEO is a system for web-based collaborative engineering of SKOS ontologies and annotation of web resources. Users collaboratively create a taxonomy, use it to annotate web resources and use it as background knowledge during search.

Resource Description Framework (RDF) is a language for representing information about resources in the World Wide Web. This Primer is designed to provide the reader with the basic knowledge required to effectively use RDF. It introduces the basic concepts of RDF and describes its XML syntax. It describes how to define RDF vocabularies using the RDF Vocabulary Description Language, and gives an overview of some deployed RDF applications. It also describes the content and purpose of other RDF specification documents.

Built on the art of ancient Greece and Rome, CLAROS is an international research collaboration, using the latest Information and Communication Technologies to enable simultaneous searching of major collections in university research institutes and museums.

Syllabs develops advanced technologies for semantic analysis of text content.

The MusicNet project is a continuation of the musicSpace project and builds on existing collaborative work between Computer Scientists & Musicologists at Southampton University and scholarly data providors Grove, RISM, Copac & the British Library.

musicSpace is a cross discipline project between Music and Electronic & Computer Science at the University of Southampton which aims to use Web2.0 & Semantic Web technologies to improve musicological research workflows.

exploring the semantic web

Foundations of Semantic Web Technologies Chapman & Hall/CRC, 2009, 455 pages, hardcover ISBN: 9781420090505 (BibTeX). Semantic Web is a maturing field of technology that continues to be the emphasis of much focused research. This foundational text introduces the standardized knowledge representation languages for modeling ontologies operating at the core of the semantic web. To support the presentation of each language, the authors explain syntax and underlying intuitions through examples, with separate treatment of the underlying formal semantics. They cover RDF Schema, Web Ontology Language (OWL), rules, and query languages, such as SPARQL. The book also presents recent developments concerning the OWL 2 revision and the forthcoming Rule Interchange Format (RIF).

Automatic Social Curation Faveeo.com is a new innovative web service that will help internet users manage the incredibly huge amount of information available everyday on blogs, news sites all around the web by leveraging and integrating the social networks and the collective intelligence they contain.

OpenStructs is an education and distribution site dedicated to open source software for converting, managing, viewing and manipulating structured data. Structured data can represent any existing data struct from the simplest attribute-value pair formats to fully specified relational database schema. Material on this OpenStructs site ranges from individual tools to complete open semantic frameworks (OSF) with which to builld comprehensive semantic instances.

iQvoc, the free open source SKOS vocabulary tool,

provides an overview of our attempts to a more visual Data Web. The term Data Web refers to the evolution of a mainly document-centric Web toward a more data-oriented Web. In its narrow sense, the term describes pragmatic approaches of the Semantic Web, such as RDF and Linked Data. In a broader sense, it also includes less formal data structures, such as microformats, microdata, tagging, and folksonomies.

Zanran helps you to find 'semi-structured' data on the web. This is the numerical data that people have presented as graphs and tables and charts. For example, the data could be a graph in a PDF report, or a table in an Excel spreadsheet, or a barchart shown as an image in an HTML page. This huge amount of information can be difficult to find using conventional search engines, which are focused primarily on finding text rather than graphs, tables and bar charts. Put more simply: Zanran is Google for data.

Anything To Triples (any23) is a library, a web service and a command line tool that extracts structured data in RDF format from a variety of Web documents. Currently it supports the following input formats: RDF/XML, Turtle, Notation 3, RDFa. Microformats: Adr, Geo, hCalendar, hCard, hListing, hResume, hReview, License, XFN and Species
