What is Vector Space Model

Chapter 20
Handbook of Research on Text and Web Mining Technologies
Is an algebraic model for representing documents (not only text) as vectors of identifiers, such as, for example, index terms. It is used in information filtering, information retrieval, indexing and relevancy rankings. Its first use was in the SMART Information Retrieval System.

Abstract
In this chapter, we present a thesaurus application in the field of text mining and more specifically automatic indexing on the set of descriptors defined by a thesaurus. We begin by presenting various definitions and a mathematical thesaurus model, and also describe various examples of real world thesauri which are used in official institutions. We then explore the problem of thesaurus-based automatic indexing by describing its difficulties and distinguishing features and reviewing previous work in this area. Finally, we propose various lines of future research.

Swarm Intelligence in Text Document Clustering
The vector space model (VSM) is an algebraic model used for information filtering and information retrieval. It represents natural language documents in a formal manner by the use of vectors in a multi-dimensional space. It was used for the first time by the SMART Information Retrieval System.

Clustering Methods and Tools to Handle High-Dimensional Social Media Text Data
An algebraic model in NLP that considers the relationship between text (words and documents) and represent similarities as a vector of identifiers. This model assumes two requirements: (1) each term is unique, and (2) the terms have no order. Thus, the relevance of a word or document is equal to the word or document query similarity.

Applying the Immunological Network Concept to Clustering Document Collections
One of classical representations of document content. The documents are points (or vectors rooted in coordinate origin) in this high-dimensional space (spanned by terms being coordinate axes), with the point (vector) coordinates reflecting frequencies of different terms (linearly or in a more complex manner) in a given document
