Like many newspapers, the New York Times links the first mention of well known entitles in its articles to a reference page. For example, a mention of Barack Obama links to a page which is a collection of basic information on President Obama and links to relevant stories and other resources that the Times has created.
Now the Times is also using RDF to publish some of information as linked open data. Yesterday the Times announced the publication of an LOD collection covering about 5,000 people at http://data.nytimes.com/ under under a Creative Commons 3.0 Attribution License and plan to put their full collection of 30K topics online soon.
“Over the last several months we have manually mapped more than 5,000 person name subject headings onto Freebase and DBPedia. And today we are pleased to announce the launch of http://data.nytimes.com and the release of these 5,000 person name subject headings as Linked Open Data.
Over the next several months, we plan to expand http://data.nytimes.com to include each of the nearly 30,000 subject headings we use to power Times Topics pages, a collection that includes locations, organizations and descriptors in addition to person names.”

OWL 2, the new version of the Web Ontology Language, officially became a W3C standard yesterday. From the W3C press release:
“Today W3C announces a new version of a standard for representing knowledge on the Web. OWL 2, part of W3C’s Semantic Web toolkit, allows people to capture their knowledge about a particular domain (say, energy or medicine) and then use tools to manage information, search through it, and learn more from it. Furthermore, as an open standard based on Web technology, it lowers the cost of merging knowledge from multiple domains.”

Wolfram|Alpha is an interesting query answering system developed by Wolfram Research that is a blend of a question answering system and a Semantic Web alternative. It tries to interpret and answer queries expressed as a sequence of words from a large collection of interlinked tables. Oh, and Mathematica is in thrown in for free. A free Web version was released last Spring.
The news today is that Wolfram|Alpha has released an API, as noted in their blog:
“The API allows your application to interact with Wolfram|Alpha much like you do on the web—you send a web request with the same query string you would type into Wolfram|Alpha’s query box and you get back the same computed results. It’s just that both are in a form your application can understand. There are plenty of ways to tweak and control the results, as well.”
The pricing plan runs from $60/month for 1000 (6 cents a query) queries to $220K for up to 10M queries/month (2.2 cents a query). programming language bindings are available for Java, PHP, Perl, Python, Ruby and .NET.
Their original web interface remains free, but the TOS specifies that it “may be used only by a human being using a conventional web browser to manually enter queries one at a time.”
