OpenCalais Meetup
Meetup Description
Tom Tague will be presenting Calais 4.0 - and its connection to the Linked Data cloud - to reporters, editors, Semantic Web aficionados, and developers alike in Washington DC on March 5, 2009. The DC Area Online News Association Meetup will also be joining us at this event.
Specifically, Tom will address the 'Linked Content Economy,' an evolving ecosystem of enriched and connected content that puts semantic metadata and open data assets to work in everyday media, content applications and Web-based services of all kinds.
Parking is available under the building, and the location is walking distance from McPherson Square and Metro Center stations.
Refreshments will be served.
Calais: Connect. Everything.
We want to make all the world's content more accessible, interoperable and valuable. Some call it Web 2.0, Web 3.0, the Semantic Web or the Giant Global Graph - we call our piece of it Calais.
What Calais does sounds simple – what you do with it could be simply amazing.
The Core: The Calais Web Service
The Calais Web Service automatically creates rich semantic metadata for the content you submit – in well under a second. Using natural language processing, machine learning and other methods, Calais analyzes your document and finds the entities within it. But, Calais goes well beyond classic entity identification and returns the facts and events hidden within your text as well.
Take a look at the Document Viewer for a small demonstration of what Calais can do.
This metadata gives you the ability to build maps (or graphs or networks) linking documents to people to companies to places to products to events to geographies to… whatever. You can use those maps to improve site navigation, provide contextual syndication, tag and organize your content, create structured folksonomies, filter and de-duplicate news feeds, or analyze content to see if it contains what you care about.
The Tools: A Growing Ecosystem of Calais-Enabled Capabilities
The Calais Web Service is a powerful capability - but using it to deliver value to real people requires applications and the tools to build them. Major focus areas of the Calais initiative are delivering the tools with which to build great applications and fostering the community of developers that will make those applications happen.
To learn more about the growing set of Calais tools please take a moment to visit the Gallery and Tools sections of the site.
The "Open" in Calais
The web service is free for commercial and non-commercial use. We’ve sized the initial release to handle millions of requests per day and will scale it as necessary to support our users.

Diary: Week of 2/23/2009 - 3/1/2009
Sunday, March 1 -- Coupons for free small subs at Quiznos in Alexandria. Too bad one of them didn't participate in the promotion. Hoang-Anh drove back to school around 2. Finished watching 'The Express' at home - good movie. Finishing up SWE625 Stage 4 - charter, whole document. Need to prepare for Quiz #1. Excited about having the braces taken off tomorrow after 3 long years.

SPARQL for the Pragmatic Ontologist
SPARQL
SPARQL is READ-ONLY!
Jena ARQ Extensions (SPARQL 2 Candidates)
1st Query: Find the country names
SELECT ?country ?name
WHERE {
?country rdf:type country:Country .
?country country:name ?name
}
OR
SELECT ?country ?name
WHERE {
?country a country:Country .
?country country:name ?name
}
OR
SELECT ?country ?name {
?country rdf:type country:Country ;
country:name ?name
}
OR
SELECT ?country ?name {
?country country:name ?name
}
2nd Query: Find the states and their cities sorted by ascending state, then city name, then by descending city name
SELECT ?state ?city
WHERE {
?cityR city:name ?city ;
Uscity:state ?stateR .
?stateR state:name ?state
} ORDER BY ASC(?state) DESC(?city)
Compactified Expression
SELECT ?state ?city
WHERE {
?cityR city:name ?city;
uscity:state [state:name ?state]
} ORDER BY ASC(?state) DESC(?city)
SELECT ?state ?capital ?airport
WHERE {
?stateR state:name ?state ;
state:capital ?capitalR .
?capitalR city:name ?capital
OPTIONAL {
?airportR airports:city ?capital ;
airports:airport ?airport
}
}
3rd Query: Select with UNION
SELECT ?state
WHERE {
{
?stateR state:borderstate usstate:AL, usstate:TN .
?stateR state:name ?state .
}
UNION
{
?stateR state:borderstate usstate:ID .
?stateR state:name ?state .
}
}
4th Query: Find all states that do NOT border another state
SELECT ?state
WHERE {
?stateR state:name ?state .
OPTIONAL {
?stateR state:borderstate ?borderState .
}
FILTER(!bound(?borderState))
}
FILTER means "keep".
With !bound() we effectively look for the absense of a resource.
5th Query: Find all states, and cities, where the city name begins with the letter 'Y'
SELECT ?state ?city
WHERE {
?cityR uscity:state ?stateR
?cityR city:name ?city .
?stateR state:name ?state
FILTER(regex(xsd:string(?city), "^Y"))
}
Cast untyped literals into datatype needed by function.
Filter early, near the top of an expression
-if a condition is not met the pattern match aborts immediately.
User OPTIONAL sparingly, they will slow down a query, sometimes drastically.
Use ASK when you do need the results of the match.
DISTINCT and ORDERED BY may also be slow over large result sets.
USE LIMIT and OFFSET with large result sets.
6th Query: DISTINCT avoids duplicate result sets
SELECT DISTINCT ?state ?city
WHERE {
?person uscity:address ?address .
?address uscity:city ?city .
?city uscity:state ?state
}
7th Query: CONSTRUCT Query
CONSTRUCT allows us to specify a graph to return.
CONSTRUCTed graphs are not inserted into the queried graph - but some tools allow the constructed graph to be asserted.
CONSTRUCT {
?countryR owl:sameAs ?nationR
}
WHERE {
}
Start comments anywhere with "#".
Use LET() to assign variables.
Use INSERT before DELETE to move data.
The graph can also be a variable.

Hello President Barack Obama
Our 44th President.
Tuesday, January 20th, 2009 at 12:01 pm
Welcome to the new WhiteHouse.gov. I'm Macon Phillips, the Director of New Media for the White House and one of the people who will be contributing to the blog.
A short time ago, Barack Obama was sworn in as the 44th president of the United States and his new administration officially came to life. One of the first changes is the White House's new website, which will serve as a place for the President and his administration to connect with the rest of the nation and the world.
Millions of Americans have powered President Obama's journey to the White House, many taking advantage of the internet to play a role in shaping our country's future. WhiteHouse.gov is just the beginning of the new administration's efforts to expand and deepen this online engagement.
Just like your new government, WhiteHouse.gov and the rest of the Administration's online programs will put citizens first. Our initial new media efforts will center around three priorities:
Communication -- Americans are eager for information about the state of the economy, national security and a host of other issues. This site will feature timely and in-depth content meant to keep everyone up-to-date and educated. Check out the briefing room, keep tabs on the blog (RSS feed) and take a moment to sign up for e-mail updates from the President and his administration so you can be sure to know about major announcements and decisions.
Transparency -- President Obama has committed to making his administration the most open and transparent in history, and WhiteHouse.gov will play a major role in delivering on that promise. The President's executive orders and proclamations will be published for everyone to review, and that’s just the beginning of our efforts to provide a window for all Americans into the business of the government. You can also learn about some of the senior leadership in the new administration and about the President’s policy priorities.
Participation -- President Obama started his career as a community organizer on the South Side of Chicago, where he saw firsthand what people can do when they come together for a common cause. Citizen participation will be a priority for the Administration, and the internet will play an important role in that. One significant addition to WhiteHouse.gov reflects a campaign promise from the President: we will publish all non-emergency legislation to the website for five days, and allow the public to review and comment before the President signs it.
We'd also like to hear from you -- what sort of things would you find valuable from WhiteHouse.gov? If you have an idea, use this form to let us know. Like the transition website and the campaign's before that, this online community will continue to be a work in progress as we develop new features and content for you. So thanks in advance for your patience and for your feedback.
Later today, we’ll put up the video and the full text of President Obama’s Inaugural Address. There will also be slideshows of the Inaugural events, the Obamas’ move into the White House, and President Obama’s first days in office.
