fr.univnantes.termsuite.engines.contextualizer.CrossTable

public class CrossTable
extends java.lang.Object

An index (often called cross table) that helps to compute the association rate of two terms, i.e. their amount of co-occurrency in the corpus.

Constructor Detail

CrossTable

public CrossTable(java.util.Map<Term,com.google.common.util.concurrent.AtomicDouble> aPlusB,
                  java.util.Map<Term,com.google.common.util.concurrent.AtomicDouble> aPlusC,
                  int totalCoOccurrences)

Constructs this cross table with a term index and inits the table with all co-occurrences of the term index's terms. This init process is based on terms' context vectors, which must be computed before invoking this constructor.

Throws:

java.lang.NullPointerException - if terms' context vectors are not already computed

java.lang.NullPointerException - when the context vectors of term index terms are not
