User Study on Keywords Summaries (a.k.a. Word Clouds)

Goal: Test effectiveness of alternate visual representations for keyword summaries.

Keyword Summaries: A set of words or phrases extracted from text collections often with the goal of representing the overall content of the text. Usually associated to a importance metric like frequency.

[Word + Value]

Design space

The design space is divided in 2 basic elements:

  • Layout: How the words are arranged on the screen
  • Mark: How each word and its value is represented visually
    • Word as value mark: In this case the value of each word is mapped to features of the word itself like color and size.
    • Additional mark for value: In this case the value of each mark is mapped to features of an additional mark associated with each word. E.g circle area, bar length
