Twenty-five percent of your course grade depends on your leading a mini-session (roughly 1 hour) of class dedicated to a topic of your choosing. The focus of the session should be a particular computational problem and how it relates to the digital humanities (does it arise from DH? has/will its solution help DH?) You should identify one or two readings and a "case study" tool or project, which you will share with the class at least a week before your session. We will collectively decide how these session should be structured.
This element of the course is intended to give you the opportunity to become (more) expert in an area of interest to you—I expect that identifying a few interesting artifacts will require you to look at a couple dozen, at least, and there's nothing like teaching to solidify your understanding of a subject.
You should have a topic identified (to share with the class) by September 24 (our 4th meeting). This can be a topic related to one of the already-scheduled classes—maybe you want to look at an angle of computational musicology—or it can be another interest you have or would like to develop.
