CoOccurrence.TermSeen

public class TermSeen

Nina Tahmasebi This class is used internally by Factory
TermSeen is used to keep track of terms encountered in the text. The term should be a dictionary item with the value 2 or -1. That is, TermSeen does not store part-of-term, only final terms. When the term is a single-word term startPos = endPos, where starting and ending position indicate where the term was encountered in text. When term is a multi-word term endPos- startPos indicates the length of the term.

When calculating co-occurrences a TermSeen a co-occurs with another TermSeen b iff b.startPos - a.endPos <= w.

Instances of this class can be cleared out after processing a document in the collection, because they are specific only to that document., Nina Tahmasebi, L3S Research Center
