Syntax
public enum DFRBasicModelFields
| Name | Description |
|---|---|
| BE | Limiting form of the Bose-Einstein model. The formula used in Lucene differs slightly from the one in the original paper: F is increased by tfn+1 and N is increased by F |
| D | Implements the approximation of the binomial model with the divergence for DFR. The formula used in Lucene differs slightly from the one in the original paper: to avoid underflow for small values of N and F, N is increased by 1 and F is always increased by tfn+1. |
| G | Geometric as limiting form of the Bose-Einstein model. The formula used in Lucene differs slightly from the one in the original paper: F is increased by 1 and N is increased by F. |
| IF | An approximation of the I(ne) model. |
| IN | The basic tf-idf model of randomness. |
| INE | Tf-idf model of randomness, based on a mixture of Poisson and inverse document frequency. |
| P | Implements the Poisson approximation for the binomial model for DFR. |
