The following four texts are different summaries of "Trishka's Caftan", a short fable by Ivan Krylov, generated by Autosummarize at different extraction percentages. At each percentage level a certain number of lines are extracted; here each sentence is ranked according to its importance in 5% increments. Together they form a set of cascading summaries in the sense that they can be read at different summarization levels. Presented below are four different ways to visualize the reading at different levels :
  1. Percentage tags indicate the rank of the extracted text. Thus at the 5% level only the first sentence is extracted and proposed as a summary. Each percentage tag includes the sentences at a lower percent. For example 20% summarization will include all sentences marked 20% and below, not just the one marked 20%. 
  2. Tabs are used to indent sentences according to rank. 
  3. A grid, much like tabs, indicates rank. 
  4. Indent plus outline styles indicate rank.

The final table compares the results from another summarization system, Pertinence Mining, with Autosummarize.

“Trishka’s Caftan” by Ivan Krylov (with ranking by Word)


(5%) Trishka’s caftan got torn at the elbows.

What is there to spend a long time thinking about? He took a needle.

He cut a quarter off of each sleeve,

And patched the elbows. The caftan is all ready again.

Only the arms have become one quarter barer.

So what, is that a misfortune?

However, everybody is laughing at Trishka.

But Trishka says: Well I am no fool,

And I will remedy that trouble.

(15%)I will patch the sleeves and make them even longer than before.

(10%)Oh, Trishka is nobody's fool!

(20%)He cut off the tails and hems,

(25%)And made the sleeve endings longer.

(30%)and now my Trishka is happy.

(35%)Although he is wearing a caftan,

That is shorter than many an undershirt.

I have sometimes seen certain gentlemen

Who, having made a mess of their affairs,

Then correct them in a similar way;

(40%) And lo! (45%)They are sporting Trishka’s caftan.
