Semantic Web 14
microformats) to be automatically interpreted as RDF, so publishers only need to use a single format, such as
HTML.Projects
This section lists some of the many projects and tools that exist to create Semantic Web solutions.[34]
DBpedia
DBpedia is an effort to publish structured data extracted from Wikipedia: the data is published in RDF and made
available on the Web for use under the GNU Free Documentation License, thus allowing Semantic Web agents to
provide inferencing and advanced querying over the Wikipedia-derived dataset and facilitating interlinking, re-use
and extension in other data-sources.FOAF
A popular vocabulary on the semantic web is Friend of a Friend (or FoaF), which uses RDF to describe the
relationships people have to other people and the "things" around them. FOAF permits intelligent agents to make
sense of the thousands of connections people have with each other, their jobs and the items important to their lives;
connections that may or may not be enumerated in searches using traditional web search engines. Because the
connections are so vast in number, human interpretation of the information may not be the best way of analyzing
them.
FOAF is an example of how the Semantic Web attempts to make use of the relationships within a social context.SIOC
The Semantically-Interlinked Online Communities project (SIOC, pronounced "shock") provides a vocabulary of
terms and relationships that model web data spaces. Examples of such data spaces include, among others: discussion
forums, blogs, blogrolls / feed subscriptions, mailing lists, shared bookmarks and image galleries.NextBio
A database consolidating high-throughput life sciences experimental data tagged and connected via biomedical
ontologies. Nextbio is accessible via a search engine interface. Researchers can contribute their findings for
incorporation to the database. The database currently supports gene or protein expression data and sequence centric
data and is steadily expanding to support other biological data types.References
