Webscaled: Data marketplace - Buy and sell data

Cross-Pollinating DBpedia and FreebaseNow that Freebase is available as Linked Data a big question that comes to mind is whether these two major projects will move to assimilate one another. DBpedia and Freebase – two endeavors primarily focused on curating unstructured and semi-structured data about everything and releasing it back into the wild (with structure) – get the bulk of their information from Wikipedia, so the amount of topical overlap is assumed to be extremely high. DBpedia gains new information when it extracts data from the latest Wikipedia dump, whereas Freebase, in addition to Wikipedia extractions, gains new information through its userbase of editors.

FreebaseAt ISWC2008 Freebase released its new RDF service for generating RDF representations of Freebase topics, allowing Freebase to be used as Linked Data! To obtain the RDF data for a topic send a GET request to http://rdf.freebase.com/rdf/some.topic.id where "some.topic.id" is replaced by the desired topic identifier (slashes in the identifier must be replaced by dots). Topic data can be represented as N3, RDF/XML or Turtle depending on the preferences expressed in your client's HTTP Accept header. Try it out with the Freebase topic Semantic Web.

ReadWriteWeb just posted an interesting article about investor opportunities and pitfalls in the Semantic Web space. The questions were asked to a panel of industry insiders at the SemTech 2008 conference. Panelists include Amanda Reed (Palomar Ventures), Eghosa Omoigui (Intel), and Stephen Hall (Vulcan Capital). This information can be very useful if you're looking to start a business within the Semantic Web industry.

QDOSQDOS, measurer of digital presence, has built an interface that lets you search for a FOAF profile. You can search for an individual by their email address or by the URL to their blog or homepage. Their goal is to index and make visible the entire FOAF social graph. If I'm not mistaken they're also helping to extend the social graph by republishing data provided by its users through its primary service (very cool indeed).

I got an email from Dolors Reig about his Semantic Web planet-type site, Planeta Web Semántica, an aggregator of Semantic Web news in Spanish. The site indexes feeds in both Spanish and English to make up for the shortage of Spanish-language Semantic Web activity in the blogosphere. I doubt this will be so in the near future as Semantic Web concepts continue to gain traction with people around the world. The site sports a clean layout and I like that you're given the ability to comment on each news item. This is an excellent resource for those whose primary language is Spanish.

When constructing the Semantic Web, we are actually building two varied aspects simultaneously. One aspect is the Web that includes things such as the communication protocols, the Web data presentation formats, and so on. In particular, we have invented new technologies such as RDF, OWL, SPARQL, and other W3C recommended Semantic Web standards. The other aspect is the semantics that represent the meanings of Web data. Building semantics is, however, different from building the Web.

Today finally I logged in to Twine the first time. I was reading yesterday about some shortcomings of the system, so I was keen on trying out the system by myself to get my own impression.

It's true that the system isn't as easy to understand as del.icio.us or other bookmarking tools. It takes a while until you get used to all those additional ways you can navigate through the system. Remember: "Twine looks at content and parses it automatically for the names of people, places, organizations and other subject tags. Users are then able to navigate between related content, view recommended content and connect with recommended people with related interests."

Unlike traditional search engines, which crawl the Web gathering Web pages, Semantic Web search engines index RDF data stored on the Web and provide an interface to search through the crawled data. Below is a list of Semantic Web search engines that are currently under development.
