Document Frequency: DF
•
# Documents the term occurs in
•
Assumptions:
• Terms that occur in fewer documents are more specified 
to a document and more descriptive of the content: 
rarity matters
• Terms that occur in most documents are common 
words, not as descriptive
• Is it true?
• Sometimes “yes”
• Sometimes just reflect textual variants (synonyms), regional 
differences, personal style

DF: smaller is better
•
We often want a larger number to be “better”
•
Solution: IDF 
• Too severe if we define
IDF = # docs / # docs with term
• Typical definition: 
IDF = log10( 1 + # docs / # docs with term)
• Why? Because it seems to work better

Tying Them Together: TF-IDF
•
Separately, DF and IDF can be good features
•
Together, they represent a good idea
•
TF-IDF = TF * IDF
•
Higher frequency of terms that are rare may 
indicate a very important concept
•
Why multiply? Are these “independent”?
•
No, but multiplying seems to work just fine
