The art and science of exploiting near-similar text and images

Submitted Jun 5, 2013

Big Data, by its inherent nature, will have near-similar items. Identifying the repetitions and, even better, leveraging them to get your job done is both an art and science. The goal of this talk is to share some experiences with this and to get you excited about this.


I will first motivate how data repetitions provide an opportunity in several tasks: image recognition, spam detection, string matching, etc. I will then talk about specific techniques for scalably identifying such near-duplicates: signature-based near-duplicate image detection, sequence mining, new string similarity measure. By then, hopefully, you’re excited enough to take a relook at your data.


Ability to look at the big picture without being bogged down by details. And the ability to look at details after that.
