Questions about Zingg's ML models and libraries used for entity resolution tasks

Sonal Goyal hello, thanks for the warm welcome in Introduce Yourself! I'm auditing various projects for entity resolution and stumbled upon this one. I wasn't able to find any info on what actual ML/statistical models zingg uses. So I thought I'd come here and the community directly. What exactly is zingg doing under the hood, w/r/t modeling? (Some combination of unsupervised clustering into random forest classification, perhaps?) What libraries is it using for each of those parts? (please direct me to the appropriate channel if this isn't the right one)
