Word Frequency |
Iterate over the contents of a file and calculate the frequency of words. |
In this project, you will use Ruby's File class and your knowledge of iterators to calculate the frequency of words in a text file. A starter file with a class and some method names is provided, as is a test suite for your code.
To calculate the frequency of words, you must:
- remove punctuation
- normalize all words to lowercase
- remove "stop words" -- words used so frequently they are ignored
- go through the file word by word and keep a count of how often each word is used
When your program is complete, you should be able to run ruby wordfreq.rb seneca_falls.txt and get a printed report like this:
her | 33 *********************************
all | 12 ************
which | 12 ************
they | 7 *******
their | 7 *******
she | 7 *******
this | 6 ******
them | 6 ******
women | 6 ******
rights | 6 ******
The class is located in wordfreq.rb in the 'starter_files' folder. To run the tests to see if your code is correct, run ruby wordfreq_test.rb.
