Description
Interface Summary | |
---|---|
DocumentRewriter | An interface for classes that rewrite documents, for example for adding semantic information. |
ElementFilter | Interface for classes that decide whether or not to accept elements in XML documents. |
Oracle | An oracle decides whether ElementFilter s
should match elements. |
SkipHandler | A handler that is called by
FilteringTokenWalker whenever some tokens
are skipped. |
Class Summary | |
---|---|
EmbeddingElements | Determines which elements in a document contain extractions (or parts of extractions). |
FilterEvaluator | A static class that allows to evaluate the precision, recall, and F1 measure of an element filter. |
FilteringTokenWalker | A token walker that only invokes a provided
TokenProcessor on the subset of tokens
that are children of an element accepted by a provided
ElementFilter . |
PredictionRewriter | A prediction rewriter uses predictions from another process (e.g. named entities) and stores them as XML elements to provide additional semantic information. |
PredictionRewriter2 | A variant of the prediction rewriter that uses predictions from another process (e.g. named entities) to provide additional semantic information. |
RepresentationFilter | A trainable filter that uses a
Representation to convert elements into
feature vectors. |
TrainableFilter | An abstract filter that uses a
trainable classifier
for training. |
TrainableFilteringTokenWalker | A filtering token walker that can be trained. |
This packages provides generic filtering and rewriting functionality. It also provides implementations for sentence filtering (the first step of a double classifiation approach to information extraction) and prediction-based document rewriting ("weakly hierarchical mode").
