Understanding the ∣{d∈D:t∈d}∣ Expression in IDF

yjyuwisely 2023. 9. 18. 16:46

In the expression ∣{d∈D:t∈d}∣

  • {}: denotes a set.
  • d∈D: means "document is in the set " (i.e., is one of the documents in the corpus ).
  • t∈d means "term t is in document " (i.e., the term t appears in the document ).
  • : can be read as "such that".

So, {d∈D:t∈d} describes the set of all documents in the corpus such that the term t appears in d.

In plain English, it represents the set of all documents where the term t appears. The outer ∣∣ then calculates the size of this set, which means it counts the number of documents that contain the term t.
