freebase semantic web wikipedia

Freebase is a masculine but complicated human-curated database.

Nodejs is a straight-talkin language that takes no guff

Giddyup

  npm install freebase

then:

  var freebase= require('freebase');
  freebase.description('tom cruise', {})
  //"Tom Cruise, is an American film actor.."

Showin' off

it's built to be as flexible as possible. all methods return the same things:

  freebase.image("/en/thom_yorke", {})
  freebase.image("thom yorke", {})
  freebase.image("http://www.myspace.com/thomyorkemusic", {})
  freebase.image({"name":"thom yorke", "id":"/en/thom_yorke"}, {})
  freebase.image(["/en/radiohead","thom yorke"], {})

it's a good idea to include your api_key in each method:

  freebase.sentence("meatloaf", {type:"/food/food", key:"MY_API_KEY"})

the paramaters are lazy, if you're lazy.

In the friggin browser

Demo - freebase.min.js == 63kb

  <script src="http://code.jquery.com/jquery-latest.js"></script>
  <script src="https://rawgit.com/spencermountain/Freebase.js/master/client_side/freebase.min.js"></script>
  <script>
  $(document).ready(function(){

    $.freebase.description("tony hawk", function (r){
      $('body').append(r)
    })

  })
  </script>

In the shell:

the library can be run in the console, with the optional second parameter as the method:

 freebase george clooney
   # {  "mid": "/m/014zcr", "id": "/en/george_clooney" ... }
 freebase sentence george clooney
   #"George Timothy Clooney is an American actor, film director, producer, and screenwriter."

Writing to Freebase:

####Oauth is hard, but you can do it. Instructions:

Register a project at [https://code.google.com/apis/console](google api console) and enable the Freebase API
In the 'Credentials' section, create a new Client ID -> 'installed application', 'other'
Add your data to './auth/credentials.js'
Run node ./auth/authenticate.js
You will be given a url to visit in your browser, which gives you an OAuth code.
Paste the oAuth code, and you'll be given the end tokens.

thats all you need to include in your request:

  freebase.add_type("/en/the_who", {type:"/music/artist", token: your_access_token})

  freebase.add_alias("/en/melanie_chisholm", {alias:"Sporty Spice", token: your_access_token})

You'll need to get a new token after about 3 hours. (Don't commit your credentials.)

If you're doing inference, or writing a bot, check out freebase_garden

##Documentation Each method takes the following form:

freebase.method( "query", {options}, callback() ) it supports this form:

freebase.method( "query", callback() ) and also this form, where the callback defaults to console.log()

freebase.method( "query" )

here are some options that you can ship in to any method:

{ nodeCallback: true, // use the 'error-first' callback form -> callback(error, result){}
  key: "MY_API_KEY", // good idea to include your freebase key, to avoid errors
  limit: 2, // truncate results
  debug: true, // print out the urls being fetched
}

Basic methods

####MQLread API MQL documentation

Books about planets:

  var query=[{
    "type":  "/astronomy/planet",
    "name":  null,
    "/book/book_subject/works": []
   }]
  freebase.mqlread(query, {}, function(r){console.log(r)})

the options object will ship any paramaters to the freebase api.

####Pagination Every Tornado, ever

  query=[{
    "type":"/base/disaster2/tornado",
    "name":null
   }]
  freebase.paginate(query, {max:400})
