  2. 2. “To infinity & beyond”: Where we’re headed Working with data: where are the pitfalls? - structured vs. unstructured Overview of the field - historical background and debates Sample projects and tools - textual, spatial and network analysis Resources - summer schools, workshops, teach-yourself tutorials, Twitter @a_e_lang | anouk.lang@ed.ac.uk | #adpsummer
  3. 3. Working with data as a humanities scholar Ben Schmidt, “Gendered language in teacher reviews” http://benschmidt.org/profGender  interdisciplinary  serious fun @a_e_lang | anouk.lang@ed.ac.uk | #adpsummer Randall Munroe, “Correlation”, XKCD, http://xkcd.com/552.

  10. 10. @a_e_lang | anouk.lang@ed.ac.uk | #adpsummer Twitter data: highly structured

  15. 15. @a_e_lang | anouk.lang@ed.ac.uk | #adpsummer Query 2: all instances of look as a noun (look_NN*)
  16. 16. @a_e_lang | anouk.lang@ed.ac.uk | #adpsummer Query 3: all instances of look as a verb (look_VV*) followed by a preposition (*_II) then sorted 1R, 2R
  17. 17. @a_e_lang | anouk.lang@ed.ac.uk | #adpsummer Query 4: all instances of the lemma look* sorted 1R, 2R
  18. 18. @a_e_lang | anouk.lang@ed.ac.uk | #adpsummer Pos-tagging errors: look_NN* != look as a noun
  19. 19. Data: always contingent, never objective  Johanna Drucker & the concept of ‘capta’  what kind of data curation is necessary?  who else has come up with categories/data models?  think about how to capture & structure your data early @a_e_lang | anouk.lang@ed.ac.uk | #adpsummer
  20. 20. Overview of the field: Definitional skirmishes Digital Humanities is a field of study in which scholarly applications of technology are used to perform analyses and generate insights that would be difficult or impossible to achieve without the help of technology. “digital humanities is more akin to a common methodological outlook than an investment in any one specific set of texts or even technologies”. (Matthew Kirschenbaum) @a_e_lang | anouk.lang@ed.ac.uk | #adpsummer

  26. 26. @a_e_lang | anouk.lang@ed.ac.uk | #adpsummer Some broad debates and tensions in the field • from outside the field: too empiricist, too positivistic, too uncritical of the use of computers • from within the field: not sufficiently statistically/algorithmically literate, use of black boxes • too apolitical: where are race, gender, & identity? • too focused on literature • “you’re not a real digital humanist unless you can code” • “more hack, less yack”

  41. 41. until Syuzhet provides filters that don’t cause ringing artifacts [extra lobes introduced into a graph by an ideal low-pass filter], it is likely that most foundation shapes will be inaccurate representations of the stories’ true plot trajectories. Since the foundation shape may in places be the opposite of the emotional trajectory, two foundation shapes may look identical despite having opposing emotional valences. Jockers’s claim … may be due more to ringing artifacts than to an actual similarity between the emotional structures of the analyzed novels.
