2009-09-28: OAI-ORE In 10 Minutes

Image
A significant part of my research time in 2007-2008 was spent working on the Open Archives Initiative Object Reuse & Exchange project (OAI-ORE, or simply just ORE). Producing the ORE suite of eight documents was difficult and took longer than I anticipated, but we had an excellent team and I'm extremely proud of the results. In the process, I also learned a great deal about the building blocks of ORE: the Web Architecture, Linked Data and RDF.

I'm often asked "What is ORE?" and I don't always have a good, short answer. The simplest way I like to describe ORE is "machine readable splash-pages".

We decided to apply some of the Data Mining Techniques covered in class in an attempt to predict the 2009 NFL Football season. There is a plethora of data out there that could be mined from Injury reports to betting lines but we decided to limit the scope to use the box score data for training and predictions.

Using box scores from 2003 to present we trained a number of different models from Support Vector Machines to Multilayer Perceptron Networks. The implementations of the models we are using are based on the Weka Data Mining Software. Weka contains a number of tools for experimenting wit…
