java.lang.Object

edu.illinois.cs.cogcomp.edison.features.factory.ChunkEmbedding

All Implemented Interfaces:

FeatureExtractor

public class ChunkEmbedding
extends Object
implements FeatureExtractor

Adds the following features using chunks from the specified view:

• The number of chunks contained in the constituent
• A thresholded version of the number of chunks. This is a discrete feature with four possible values: 0, 1, 2, many
• The embedding of the chunks (one of embedded-in, embeds, is, exclusively-overlaps, has-overlap, has-no-overlap, same-start-span, same-end-span). These conditions are checked using the corresponding query in Queries. This feature also includes the label of the chunk
• The number of chunks of each type embedded (as a real feature)
