Abstract Tasks Example


Journal data from VI2 and VI4

  • fields: PMC ID/PMID, publisher, journal name, article title, cost
  • types: categorical, categorial, categorical, categorical, quantitative

Abstract Tasks

Analyze -> Derive

  • cost per journal - quantitative
  • # articles per journal - quantitative
  • # journals per publisher - quantitative
  • avg cost per publisher - quantitative

Analyze -> Consume -> Discover/Present

  • identify extremes - journals with highest and lowest cost
  • summarize distribution - histogram of cost per journal
  • identify extremes - publishers with highest and lowest cost per journal
  • identify extremes - publishers with highest and lowest # of journals
  • identify correlation - # journals per publisher vs. avg cost per publisher
  • locate one - locate avg cost for a particular publisher
  • locate one - locate # journals for a particular publisher
  • compare multiple - compare avg cost for different publishers
  • compare multiple - compare # journals for different publishers
  • summarize distribution - histogram of avg cost per publisher
  • summarize distribution - histogram of # journals per publisher

Application to Project:

For each of the abstract tasks (except derive), there should be a chart that allows that task to be performed. It may be that a single chart can support multiple tasks. In your project report, you will describe which charts allow which tasks to be performed.

Once you get more familiar with your data, you can make the discover vs. present choice. Remember that discover means that you're letting the user be in charge of exploring the data and making discoveries. With present, you have already found the interesting aspects and are highlighting those for the user. You're telling a story. (Think of the Hans Rosling video - that was present.)
