Multi-Word TagCloud on Web N-gram Now

April 29th, 2010

Check out the tagCloud below, can you see why it is interesting? Please compare the two tag clouds generated from the same text (a text corpus from the title of about 2000 datasets), and see why they are different.

A Multi-word TagCloud produced from 2000 US gov dataset titles

Novel Multi-word TagCloud

Conventional Single-word Tag Cloud

Conventional Single-word TagCloud


  • Meaningful Visualization. As you may see from the caption, the first one a “MultiWord TagCloud” while the other is the conventional single-word  TagCloud. The former joints individual words into popular multi-word phrases. With the former tag cloud, I can have a better overview on what data was published at
  • Automated Process. The MultiWord TagCloud was not created by human users, but automatically generated by computer program, powered by Microsoft Web N-gram service. We can generate such tag cloud for all existing text document
  • Cloud+Crowd. Broadly, this demo shows the value of the crowd and the cloud I mentioned in my earlier blog, now big data can be tackled by the crowd (text from the entire Web) and the cloud (the high performance computational Web N-gram service).

Behind the Scene

The WWW2010 is really inspiring – making me a productive “engineer” although I came as a researcher. Today I picked up Microsoft Visual Studio and write my first C# program. I was an excellent C++ programmer back to my college time (I wrote ton of code using Visual C++ 4.0 10+ years ago). However, today is not about me being a programmer, but rather announce something that is really cool!  I would also like to thank researchers, Evelyne and Paul from Microsoft Research for their great support. My demo on data is powered by Microsoft Web N-gram Service.

Putting open Facebook data into Linked Data Cloud

April 28th, 2010

I recently build a proof-of-concept demo on getting Facebook data (public data only) into LOD   their recently announced Graph API. The demo is available at

It is fairly straightforward to convert the JSON object into RDF and make the URI dereferenceable. Now the data are linkable, but not yet linked to other LOD data.

I did see some issues when I was assigning rdf properties. Here is an example JSON from

   "id": "40796308305",
   "name": "Coca-Cola",
   "picture": "",
   "link": "",
   "category": "Consumer_products",
   "username": "coca-cola",
   "products": "Coca-Cola is the most popular and biggest-selling soft drink in history, as well as the best-known product in the world.\n\nCreated in Atlanta, Georgia, by Dr. John S. Pemberton, Coca-Cola was first offered as a fountain beverage by mixing Coca-Cola syrup with carbonated water. Coca-Cola was introduced in 1886, patented in 1887, registered as a trademark in 1893 and by 1895 it was being sold in every state and territory in the United States. In 1899, The Coca-Cola Company began franchised bottling operations in the United States.\n\nCoca-Cola might owe its origins to the United States, but its popularity has made it truly universal. Today, you can find Coca-Cola in virtually every part of the world.",
   "fan_count": 5425800

1. The JSON file from Facebook is not using the exact Open Graph Protocol terms -below is the mapping

   name  => og:title
   category => og:type
   picture  => og:image
   link  => og:url

2.2 we can reuse FOAF and DCTerms to cover some terms used in Facebook data – below is the mapping

  picture => foaf:depiction
  name => foaf:name
  from => dcterms:source
  id => dcterms:identifier
  created_time => dcterms:created
  updated_time => dcterms:modified
  category => dcterms:type
  link => foaf:homepage
