Class Term

java.lang.Object
  it.unimi.dico.islab.idbs2.kc.Term

public class Term
extends Object

Representation of a keyword of a KnowledgeChunk with associated relevance and frequency. This is in fact an association between a keyword and a knowledge chunk from which the keyword has been extracted. The same keyword could appear in more than one Term instance, every time connected with different KnowledgeChunks and, possibly, different frequency and relevance.

The following image shows the relations between the fields of this object and the fields of the wrapped database table (fields with the same color represents a mapping between relational schema and the corresponding object).
