Taking “Data Blitz” as literally as possible

I have data!

Self-promotion

Inferring meaning from words

  • Dictionaries
    • Count how many words fall in each category
    • Lots of pressure on the dictionary!
  • Other stuff?

Distributed dictionary representation (DDR)

  • Dehghani and colleagues (2017)
  • Representing words as vectors
  • Can help account for words missing from dictionary w/ similar meaning

My data

  • Billboard charts since 1993
    • Pop, country, rap, rock
  • Retrieved lyrics for around 70% overall
    • More like 90% in recent years
  • About 15,000 songs w/ lyrics
  • Focusing on each chart’s average
    • Interest in music in general, genres comparatively
