Task Scenarios

We use three representative task types of tabular data exploration in our evaluation. These tasks require both a local and a global search of the table [12] to assess special properties of the data presented and build relations among different row and column entries. We define a task taxonomy consisting of three categories.

Table 1 gives examples for the task taxonomy described.

Task No. Task Definition Task Type
1 What was the urban population count for New York in 1920? 1
2 What is the region that has the maximum rural population count in 1990? 2
3 Identify the regions that have a urban population count between 10,000,000 and 20,000,000 in 1990 2
4 What is the trend (increase/decrease) in the rural population count for the Northeast Region? 3
5 What is the difference between the Northeast and Midwest regions in terms of urban population count between 1950 and 1990? 3
