The multimedia interactive summary was generated from a corpus of 96 reviews.
The Treemap component of the summary allows you to zoom in and out
clicking on rectangles. Double clicking with the left button on a
rectangle with sub-rectangles zooms in until that rectangle covers the
whole screen. Double clicking with the left button on a rectangle
with no sub-rectangles zooms in until the parent of that rectangle
covers the whole screen. Right-clicking with the mouse zooms out one
level. Upon zooming in to a leaf node, the Treemap should reveal
individual rectangles for each sentence about a feature in the
hierarchy (labelled e.g. user13-3 for User #13, Sentence 3). Clicking
on a rectangle representing a sentence will cause the review in which
that sentence occurred to appear in the bottom of the screen. The
sentence text will be highlighted. The footnotes in the textual
summary serve a similar purpose. Note that some rectangles and their
colors may not be completely visible without zooming in.
