Text Classifier Model to Table

Go to Product

This node allows to transform the content of a model, which was created using the Palladian text classifier, to a KNIME table. The KNIME table contains the tokens (words, n-grams), as rows and columns for each category. Each cell for a (token, category) combination contains either an absolute or relative co-occurrence count, depending on this node’s settings. The last column gives an absolute count of the token in the trained data set.

Options

Relative counts: If enabled, the counts for the categories are given as relative values (so that they sum up to one for each term)

Input Ports

: The model data of the trained classifier.

Output Ports

: A table which contains to token-category co-occurrence matrix
: A table which contains the category priors counts/probabilities as determined by the single documents
