What Regular 
Expressions Do
Match strings: REs are pattern matchers, not “language 
interpreters”
Are more flexible than string operations in Excel, C, or 
other languages
Key: wildcards
• Allows matching varying length patterns
• Allows matching existence or non-existence of patterns
• Matches combinations very efficiently
have rules (assumptions) that describe how they match
Typically, they start at the “left” end of a chunk of text, 
and match the leftmost, longest string

How Widespread is the Use 
of  Regular Expressions?
First chapter in the book “Speech and Language 
Processing: An Introduction to Natural 
Language Processing, Linguistics, and Speech 
Recognition” (Jurafsky and Martin, 2010, ISBN 
978-7-115-23892-4) is on Regular Expressions
• “One of the unsung successes in standardization 
in computer science has been the regular 
expression (RE), a language for specifying text 
search strings.”
• “the regular expression is an important 
theoretical tool [used] throughout computer 
science and linguistics.”

What to do with Features?
Create new columns for each document (row)
• Each column represents a measure for a keyword or 
concept (phrase)
• Can include multiple representations for each concept 
(keyword flags and TF-IDF, for example)
But...
• Could be many (way too many) columns!

Reducing Keyword 
Features
Remove “useless” words: stopwords, articles, etc.
• Is “The” in “The Who” useless?
Assess features one-at-a-time
• Keep features with predictive power (via chi-square or other test)
Reduce features through Principal Component Analysis (PCA), 
Singular Value Decomposition (SVD), or clustering
• Determines which features “load” together (i.e. are correlated)
One approach: keep factors that explain enough variance in data
Cosine transform
• Monotonic (for angles between 0 deg to 180 deg)
Product of TF-IDF for document and TF-IDF for corpus
Normalize by TF-IDF for all documents (sqrt of sum of squares)
