Human-written summaries of line graphs

This experiment was intended to help develop the automatic generation of summaries capturing the most salient information conveyed by line graphs in popular media, as well as to evaluate the output of such a system.

Here you can find the experiment package. In this folder you can also find a short paper that contains details on the experiment.

Line Graphs Steepness Assessment

The steepness assessment experiment intended to acquire knowledge about how humans judge a trend to be sharp in a certain degree. 21 subjects were recruited by email and took the experiment through Qualtrics. They were all 18 or older and had fluency of the English language. The subjects were provided with images containing a single segment which represented one of falling, rising, or stable trends. The slope of the trends varied by 10 degrees from 5 to 355 degrees (with three exceptions 0, 2 and 358 degrees). They were asked to classify the trend one of: - Flat - Relatively flat but rising/falling - Slightly rising/falling - Rising/Falling - Steeply rising/falling

The trends were out of order, showing up randomly for each participant. The report from Qualtrics can be found here.
