    Powerset's first product is a search and discovery experience for Wikipedia, launched in May 2008. Powerset's technology improves the entire search process. In the search box, you can express yourself in keywords, phrases, or simple questions. On the search results page, Powerset gives more accurate results, often answering questions directly, and aggregates information from across multiple articles. Finally, Powerset's technology follows you into enhanced Wikipedia articles, giving you a better way to quickly digest and navigate content.


Semantic MediaWiki Sandbox

Social Semantic Web Wiki (German)

    On the occasion of the recent publication of our book, Social Semantic Web, we have created an accompanying wiki for you to explore the contents of the book and obtain information about its authors. Staying true to the motto "Eat your own dog food", the Semantic Web Company has used a semantic wiki for that purpose.


True Knowledge

    True Knowledge is a pioneer in a new class of Internet search technology that's aimed at dramatically improving the experience of finding known facts on the Web. Our first service - the True Knowledge Answer Engine - is a major step toward fulfilling a longstanding Internet industry goal: providing consumers with instant answers to complex questions, with a single click.

    Picking up where search engines leave off, True Knowledge's path-breaking Answer Engine automates the laborious, time-consuming work that users generally must do to get final answers to their questions. True Knowledge does this by structuring data in a way that enables computers to work and think like humans do, drawing inferences and conclusions when needed to find the information that's requested. Another key differentiator: True Knowledge is tapping subject matter experts around the globe to build its information repository - bringing together the benefits of machine-driven automation and people-driven intelligence.



    People use Twine to keep track of their interests. Twine is a new way for you to collect online content -- videos, photos, articles, Web pages, products -- and bring it all together by topic, so you can have it in one place and share it with anyone you want. ... It helps you collect information in a new, highly personalized, convenient way. You can use Twine alone, with friends, groups and communities, or even in your company.

    And Twine is smart. It's powered by semantic understanding, which means Twine gets to know you. It automatically learns about your interests and makes connections and recommendations tailored to you. The best part: The more you use Twine, the more useful it becomes.


Virtuoso SPARQL Query Form

    The Virtuoso SPARQL query service implements the SPARQL Protocol for RDF (W3C Working Draft 25 January 2006), providing SPARQL query-processing for RDF data available on the open Internet.

    The query service implementation extends the standard protocol by providing multiple output-formats alongside the standard XML results serialization. At present, this uses additional query parameters, although content-negotiation will be supported soon.



    This is the Watson Web interface for searching ontologies and semantic documents using keywords. This interface is subject to frequent evolutions and improvements. If you want to share your opinion, suggest improvement or comment on the results, don't hesitate to contact us...
