Document Word Vector

A Document Word Vector is a Word Vector that is a Document Vector (representation of a Document).

• AKA: Text Vector, Vectorized Document, Document Term Vector, Document Indexing Vector.
• Context:
  • It can be used by:
    • an Information Retrieval Algorithm.
    • a Document Clustering Algorithm.
    • a Document Classification Algorithm.
  • It can make use of an Indexing Vocabulary that defines the Indexing Space.
• See: Mention Vector, Passage Word Vector.

  • Many well-known methods of text clustering make use of a long list of words as vector space which is often unsatisfactory for a couple of reasons: first, it keeps the dimensionality of the data very high, and second, it ignores important relationships between terms like synonyms or antonyms. Our unsupervised method solves both problems by using ANNIE and WordNet lexical categories and WordNet ontology in order to create a well structured document vector space whose low dimensionality allows common clustering algorithms to perform well.

  • The document representation step converts text documents into structures that can be efficiently processed without the loss of vital content. At the core of this process is a thesaurus, an array T of atomic tokens (e.g., a single term) each identified by a unique numeric identifier culled from authoritative sources or automatically. ... The purpose of the document representation step is to convert each document to a weight vector whose dimension is the same as the number of terms in the thesaurus.
