Digital Humanities and small data, or close reading our way to big data?

For the Upstate THATcamp, I am interested in how digital tools might help us represent the benefits and consequences of close or slow or attentive reading, maybe using W. Shakespeare’s Sonnet 20 as an example.  I have ideas on what I would like to have happen to the poem in the process, and nearly no ideas on how to achieve it.  Thus . . . THATcamp (?).
