For our final project for CIS552: Advanced Programming, my partner and I implemented a poetry parser. The program identifies a body of text piped from STDIN as one of: haiku, rhyming poem (aba, or aabba), sonnet, or limerick.

The project source is located at: https://github.com/jamiely/poetry-parser.

The project involved using the CMU Pronouncing Dictionary found here, creating parsers for the dictionary, and base parsers that could be combined for various forms.

For example, we implemented a parser for syllables that allows us to create a haiku parser.

-- | Parses a Haiku
haiku :: PoemParser RhymeMap
haiku = do
  ns 5
  ns 7
  ns 5
  return Map.empty where
  ns = nSyllables

and a rhyming scheme parser that allowed us to recognize limericks:

aabba :: PoemParser RhymeMap
aabba = rhymeScheme "aabba" Map.empty

-- | The stress pattern of a limerick
-- note: syllable requirement is implicit
limerickStress :: PoemParser RhymeMap
limerickStress = do
  stressLine [D,U, D,D,U, D,D,U] 
  stressLine [D,U, D,D,U, D,D,U] 
  stressLine [D,U, D,D,U]<br />
  stressLine [D,U, D,D,U]<br />
  stressLine [D,U, D,D,U, D,D,U]

limerick :: PoemParser RhymeMap
limerick = limerickStress &lt;&amp;&gt; aabba 

For example, we can determine the type of the following poem:

An old silent pond… A frog jumps into the pond, splash! Silence again. – Basho

by running the program thusly:

> ./Main < extra/basho.haiku

with the result:

Opened file
Poem: 
An old silent pond...
A frog jumps into the pond,
splash! Silence again.

Dictionary:

FROG  F R AA1 G

POND  P AA1 N D
POND'S  P AA1 N D Z
SILENCE  S AY1 L AH0 N S
SILENT  S AY1 L AH0 N T
SPLASH  S P L AE1 SH
THE  DH AH0

Type: Haiku

And the following poem:

something something fox apple jacks word here pox

by running the program thusly:

> ./Main < extra/fox.rhyming

with the result:

Opened file
Poem: 
something something fox
apple jacks
word here pox
