Data on the Semantic Web is semi-structured and does not follow one fixed schema. Faceted browsing is a natural technique for navigating such data, partitioning the information space into orthogonal conceptual dimensions. Current faceted interfaces are ma
This report surveys the state of semantic web storage for RDF / triple data using existing free software tools. It takes a practical approach by targeting the work to the needs of developers, answering frequently asked questions related to this subject. The report first reviews previous work in surveying semantic web data, schema and triple stores, then gives an overview of the major systems with their feature set and maturity and then uses that information to provide a set of FAQs with answers related to storing semantic web data.
Freebase is an open database of the world’s information. It is built by the community and for the community—free for anyone to query, contribute to, build applications on top of, or integrate into their websites.
Why Dog Food?!
The call to "eat your own dog-food" is often heard in the Semantic Web research area. The motto encourages us to use the languages and tools that we are developing to support our own work and demonstrate convincing arguments for the introduction of explicit semantics.
The International Semantic Web and European Semantic Web Conference series have followed this maxim and published metadata describing the events. This metadata covers information about papers, schedules, attendees etc. Tools can then consume this information and provide services, such as intelligent scheduling or search, to conference attendees.
The Dublin Core Metadata Initiative is an open organization engaged in the development of interoperable online metadata standards that support a broad range of purposes and business models. DCMI's activities include work on architecture and modeling, discussions and collaborative work in DCMI Communities and DCMI Task Groups, annual conferences and workshops, standards liaison, and educational efforts to promote widespread acceptance of metadata standards and practices.
Calais is a web service that uses natural language processing (NLP) technology to semantically tag text that is input to the service. The tags are delivered to the user who can then incorporate them into other applications - for search, news aggregation, blogs, catalogs, you name it.
With this Web page, we are opening some aspects of hakia R&D to the view of our users. We undertook highly specific research tasks solely dedicated to the advancement of the core-competency in Web search. The main challenge is to make science work in a co
