How do ideas flow around SIGMM conferences?

The ACM Multimedia conference just celebrated its quarter century in October 2017. This is a great opportunity to reflect on the intellectual influence of the conference, and the SIGMM community in general. The progress on big scholarly data allows us to make this task analytical. I download a data dump from Microsoft Academic Graph (MAG) in February 2016. I find all papers from ACM Multimedia (MM), the SIGMM flagship conference - there are 4,346 publication entries from 1993 to 2015. I then search the entire MAG for: (1) any paper that appears in the reference list of these MM papers - 35,829 entries across 1,560 publication venues (including both journals and conferences), with an average of 8.24 per paper; (2) any paper that cites any of these MM papers - 46826 citations from 1694 publication venues, with an average of 10.77 citations per paper. This data allows us to profile the incoming (references) and outgoing (citations) influence in the community in detail.
