After downloading unixdict to /tmp:

 

 

Investigating the rules:

 

24

+/'cei' E. dict

490

+/'ei' E. dict

 

So, based on unixdict.txt, the "I before E" rule seems plausible (490 > 230 by more than a factor of 2), but the exception does not make much sense (we see almost twice as many i before e after a c as we see e before i after a c).

After downloading 1_2_all_freq to /tmp, we can read it into J, and break out the first column (as words) and the third column as numbers:

 

 

words=: >0 { allfreq

 

With these definitions, we can define a prevalence verb which will tell us how often a particular substring is appears in use:

 

(y +./@E."1 words) +/ .* freqs

 

Investigating our original proposed rules:

 

 

A generic "i before e" rule is not looking quite as good now - words that have i before e are used less than twice as much as words which use e before i.

 

 

An "except after c" variant is looking awful now - words that use the cie sequence are three times as likely as words that use the cei sequence. So, of course, if we modified our original rule with this exception it would weaken the original rule:

 

 

Note that we might also want to consider non-adjacent matches (the regular expression 'i.*e' instead of 'ie' or perhaps 'c.*ie' or 'c.*i.*e' instead of 'cie') - this would be straightforward to check, but this would bulk up the page.

Download and save wordlist to unixdict.txt.

WARNING: The problem statement is misleading as the rule only applies to syllables that rhyme with "see".

This solution uses grammars and actions to parse the given file, the <tt>Bag</tt> for tallying up occurrences of each possible thing we're looking for ("ie", "ei", "cie", and "cei"), and junctions to determine the plausibility of a phrase from the subphrases. Note that a version of rakudo newer than the January 2014 compiler or Star releases is needed, as this code relies on a recent bugfix to the <tt>make</tt> function.
