Syntax
public abstract class Normalization : objectConstructors
| Name | Description |
|---|---|
| Normalization() | Sole constructor. (For invocation by subclass constructors, typically implicit.) |
Methods
| Name | Description |
|---|---|
| Explain(BasicStats, Single, Single) | Returns an explanation for the normalized term frequency. The default normalization methods use the field length of the document and the average field length to compute the normalized term frequency. This method provides a generic explanation for such methods. Subclasses that use other statistics must override this method. |
| Tfn(BasicStats, Single, Single) | Returns the normalized term frequency. |
| ToString() | Subclasses must override this method to return the code of the normalization formula. Refer to the original paper for the list. |
