Class EVEXFeatureBuilder

This is called, when the ExampleBuilder object is created.

Parameters:

• featureSet (Core.IdSet) - The feature ids

Overrides: FeatureBuilder.FeatureBuilder.__init__

This function is called once for each sentence, before any calls to "buildFeatures". It should be used to initialize per-sentence data structures.

Parameters:

• sentenceGraph (Core.SentenceGraph) - a SentenceGraph object providing access to the aligned semantic and syntactic information of the sentence. The underlying XML can also be accessed through this class.

This is the main-function for feature generation. It is called once for each directed entity pair in the sentence.

For defining features, please use the member function "setFeature(self, name, value=1)", derived from the parent class. This ensures features get correctly tagged, if needed.

Parameters:

• entity1 (cElementTree.Element) - First entity of the candidate edge, an Interaction XML "entity"-element
• entity2 (cElementTree.Element) - Second entity of the candidate edge, an Interaction XML "entity"-element
• token1 (cElementTree.Element) - The head token of entity1, an Interaction XML "token"-element
• token2 (cElementTree.Element) - The head token of entity2, an Interaction XML "token"-element
• path (list of cElementTree.Elements (when "no_path" style is set, this is always [token1, token2])) - the shortest connecting path of tokens (Interaction XML "token"-elements)
• sentenceGraph (Core.SentenceGraph) - a SentenceGraph object providing access to the aligned semantic and syntactic information of the sentence. The underlying XML can also be accessed through this class.
