| + | ==== Embedded RDF ==== | ||
| + | |||
| + | This document describes how a subset of RDF can be embedded into XHTML or HTML by using common idioms and attributes. No new elements or attributes have been invented and the usages of the HTML attributes are within normal bounds. This scheme is designed to work with CSS and other HTML support technologies. | ||
| + | |||
| + | Note: hereafter the term HTML will be used to include both XHTML and HTML except where otherwise stated. | ||
| + | |||
| + | === Embeddable RDF === | ||
| + | |||
| + | The subset of RDF that is used in this embedding scheme is called HTML Embeddable RDF. It allows some very important parts of the RDF model to be embedded but does not attempt to extend this to the full RDF model. This is very deliberate. Other attempts at embedding RDF in HTML have required the introduction of new syntax to express all the various RDF concepts. | ||
| + | |||
| + | The relationship is: all HTML Embeddable RDF is valid RDF, not all RDF is Embeddable RDF. | ||
| + | |||
| + | === Extracting data from Embedded RDF === | ||
| + | |||
| + | **Embedded RDF Extractor** | ||
| + | This service extracts Embedded RDF from HTML using this XSLT stylesheet. | ||

| + | === Wandora === | ||
| + | |||
| + | **Wandora** is a general purpose knowledge extraction, management, and publishing application based on Topic Maps and Java. More precisely Wandora is an open source desktop application to build and manage topic maps. Wandora has graphical user interface, layered presentation of knowledge, several data storage options, rich data extraction, import and export capabilities, and open plug-in architecture. Wandora's license is GNU GPL. | ||
| + | |||
| + | {{:pl:miw:2009:wandoras_extractors.gif|}} | ||
| + | |||
| + | Wandora suits well for knowledge mashups. Wandora is capable to extract and convert various open data feeds to Topic Maps format (see image below). Beyond Topic Maps conversion this feature allows Wandora user to aggregate multidimensional knowledge bases where information from Flickr meets Geonames and Delicious, for example. Read more at documentation. | ||
| + | |||
| + | This site, WandoraWiki, is a home of Wandora software application and provides you an access point to the Wandora application and it's documentation. To contribute Topic Maps, Wandora Team has also converted several well known ontologies to Topic Maps format. These converted ontologies; WordNet, OpenCyc, Gene Ontology, Gellish, and Finnish General Upper Ontology (YSO) are available for download here in WandoraWiki. | ||

| + | === SemanticProxy === | ||
| + | |||
| + | **SemanticProxy.com** is part of the Calais Initiative from Thomson Reuters. | ||
| + | |||
| + | In the future the entire web will be one giant tightly interconnected information asset. Beyond just publishing information for humans, every site will expose its content in a way that's readable by machines. Those machines will mix, match, filter and aggregate information to greatly improve things for us humans. We're not there yet - but that's the vision of the Semantic Web. | ||
| + | |||
| + | SemanticProxy.com is a little taste of what that future might look like. What SemanticProxy does is simple: it translates the content of any URL on the web to its semantic representation in RDF, HTML or Microformats. If you're an RDF crawler hungry for a little semantic content, just point yourself at SemanticProxy.com and we'll fill you up. | ||
| + | |||
| + | Right now SemanticProxy.com is optimized for performance on 30 of the world's largest English-language news sites. In coming releases we'll continue to refine and extend its capabilities to additional areas. While you'll find it works best with news, feel free to experiment with other sites like Wikipedia or ... whatever. The results can be very encouraging. | ||
| + | |||
| + | SemanticProxy isn't intended to be a great place for humans to visit. However, little semantic machines love to come by and spend a few high-quality milliseconds. | ||
| + | |||
| + | |||
| + | === Gnosis === | ||
| + | |||
| + | Delivering Semantic Web Services - Directly to Your Desktop | ||
| + | |||
| + | Gnosis is a browser extension for Firefox and Internet Explorer that automatically analyzes content as you browse and provides a variety of tools to explore the people, places, companies, and other items that you’re reading about. In this latest release, Gnosis capability has been extended to include the following: | ||
| + | |||
| + | * Support for Firefox 3.5 | ||
| + | * Entity Count and Relevance Score for each entity that the viewer displays. | ||
| + | * Entity Disambiguation: The entity name displayed is the disambiguated name where applicable (companies, geographies, electronic products) | ||
| + | |||
| + | After installing Gnosis, simply navigate to the news site that you are interested in - one of the news sites listed below would be a good place to start. Right-click and select ClearForest Gnosis or click on the Gnosis button in the toolbar. After 1-2 seconds your page has been processed and you’re ready to explore! | ||
