Welcome to my website. My name is Matt Michelson. I received my Ph.D. from the Computer Science Department at the University of Southern California. I was a member of the Information Integration research group led by Prof. Craig Knoblock, which is part of the Information Sciences Institute. Graduate school was super fun and I learend a lot. I am now very fortunate to work as a research associate for First Quadrant.

Data and Software

Data sets

JAIR 2010 Experimental Data This is the data for our experiments in the JAIR 2010 paper (see above). This data can be used for information extraction experiments where the data is noisy and unstructured. [Info. Extraction]
Bidding For Travel data set [Record Linkage and Info. Extraction]

Software

Information Extraction from Unstructured, Ungrammatical Data using Reference Sets
This code allows for information extraction from unstructured, ungrammatical data sources (such as classified ads and auction listings) by exploiting reference sets. This implementation includes both our machine learning approach (JAIR 2008 paper) and our automatic approach (IJDAR 2007 paper). The code freely available.
BSL: Blocking Scheme Learner
This code implements the algorithm presented in the Learning Blocking Schemes for Record Linkage paper. Blocking schemes are rules to efficiently generate candidate matches in record linkage, without pruning too many true positives from the set. For more on this, please read the paper.
