Class LemmaCorpusCounts

All Implemented Interfaces:

PersistentObject

public class LemmaCorpusCounts
extends java.lang.Object
implements PersistentObject

Lemma/corpus counts.

These count objects provide summary statistics for lemma/corpus combinations. Given a lemma and a corpus, we can quickly provide the following information using a two-column index on corpus/lemma:

• The lemma's tag.
• The lemma's word class.
• The lemma's major word class.
• The collection frequency = the number of times the lemma occurs in the corpus.
• The document frequency = the number of works in the corpus in which the lemma occurs.
• The lemma's rank in the corpus among all the lemma's with the same major word class in the corpus. The rank is specified as a range.
• The total number of distinct lemmas in the corpus with the same major word class as this lemma.

These objects are used to quickly construct get info windows for words and lemmas and lexicon windows.
