Class Summary |
| AbstractWrapperLoader |
to do |
| Affix |
An Affix object stores both Pattern
and locations in the example set where the pattern does match
and doesn't, matchOk and matchWrong
respectively.
|
| BoostingFactory |
Factory for creating a boosting implementation.
|
| BWI |
A BWI object implements the Boosted Wrapper Learner
algorithm defined by Dayne Freitag and Nicholas Kushmerick.
|
| Classifier |
This class provides methods for extracting information from a text given the
model learnt during training.
|
| DefaultFieldExtraction |
This is the default implementaion of the FieldExtraction
interface. |
| DefaultWeakLearner |
A DefaultWeakLearner object implements the WeakLearner
interface.
|
| Detector |
A Detector object is a pair of patterns:
a prefix pattern and a suffix pattern. |
| Distribution |
A Distribution object represents a distribution of
weigths over the example set. |
| ExtractionResult |
Acts as an holder for the result of an extraction task.
|
| FastWeakLearner |
A FastWeakLearner object implements the
WeakLearner interface.
|
| FieldExtractionFactory |
This factory object is used to obtain implementation of
FieldExtraction. |
| LearnerFactory |
Factory for creating a weak learner.
|
| PatternTable |
A PatternTable object maps Patterns to Affixes
for a fast retrivial. |
| PatternTableBuilder |
Creates a pattern table. |
| Score |
Computes the score and confidence value of a detector. |
| StandardFieldExtraction |
This is the default implementaion of the FieldExtraction
interface. |
| TagCoupling |
A TagCoupling object couples the open tags
with the close tags. |
| Wrapper |
A Wrapper object consists of two sets
F = {F1, F2, ...,
FT} and A = {A1,
A2, ..., AT}
of detectors, and a function H : [-∞, +∞]
→[0, 1]. |
| WrapperLoader |
Loads a wrapper from a XML file. |
