 Term vector model or [Vector space model](https://en.wikipedia.org/wiki/Vector_space_model) is an algebraic model for representing text documents (and any objects, in general) as vectors of identifiers.
 
 It is used in information filtering, information retrieval, relevancy rankings, and machine learning.
