public abstract class BasicModel : objectConstructors
| Name | Description |
|---|---|
| BasicModel() | Sole constructor. (For invocation by subclass constructors, typically implicit.) |
Methods
| Name | Description |
|---|---|
| Explain(BasicStats, Single) | Returns an explanation for the score. Most basic models use the number of documents and the total term frequency to compute Inf1. this method provides a generic explanation for such models. Subclasses that use other statistics must override this method. |
| Score(BasicStats, Single) | Returns the informative content score. |
| ToString() | Subclasses must override this method to return the code of the basic model formula. Refer to the original paper for the list. |
