Language: Flesch Reading Ease
Description Flesch
Reading Ease, a readability test named after its deviser Rudolf Flesch,
is among most ubiquitously used readability tests, which are
principally employed for assessment of the difficulty to understand a
reading passage written in English. The Flesch Reading Ease score of a
passage relies solely on three statistics, namely the total numbers of
sentences, words and syllables, of the passage. Specifically, the score
is defined by the following formula: As
can be inferred from the above formula, a passage with a high Flesch
Reading Ease score tends to favor shorter sentences and words, which is
in compliance with commonsense in spite of partial accuracy. (Think of,
for instance, the word "television". Long as it may seem, it is indeed
one of the first words that any individual who studies English learns.)
A related Wikipedia entry on Flesch Reading Ease [1] suggests that
passages scoring 90~100 are comprehensible for an average American 5th
grader, and 8th and 9th graders possess the ability to follow passages
with a score in the range of 60~70, whereas passages not exceeding 30
in the score are best suitable for college graduates. The text of this
problem, all sections taken into account, scores roughly 50 as per the
calculation of Google Documents. Despite the simplicity in its
ideas, several aspects of its definition remains vague for any
real-world implementation of Flesch Reading Ease. For the sake of
precision and uniformity, the following restrictions adapted from [2]
are adopted for this problem, to which you are to write a solution that
effectively computes the Flesch Reading Ease score of a given passage
of English text. Input Output Sample Input Sample Output Source |
