NodeDocument Vector

Manipulator

This node creates a document vector for each document representing it in the terms space. The values of the feature vectors can be specified as boolean values or as values of a specified column i.e. an tf*idf column. The dimension of the vectors will be the number of distinct terms in the BoW.

Input ports

  1. Documents input table Type: Data

Output ports

  1. Documents output table Type: Data
    An output table containing the documents with the related document vectors.
  2. Model output Type: DocumentVectorPortObject
    A model containing node settings as well as column names of the term feature space.
