Wiki: Semantic Relation Detection Classifier

Semantic Relation Detection Classifier: A Semantic Relation Detection Classifier is a Predictive Classifier that maps Text to a Semantic Relation.
- AKA: Extraction Pattern, Extraction Rule, Pattern, Relation Recognition Classifier, Relation Pattern
- Context:
  - Can be a Lexical Relation Recognition Classifier, Dependency Relation Recognition Classifier, [[Text_Graph_Relation_Recognition_Classifier?]]
  - Can fill in a [[Template?]] or [[Template_Slot?]].
  - Can be learned by a Relation Detection Algorithm.
- Examples:
  - The [[Lexical_Relation_Recognition_Pattern?]] [<NAMED ENTITY>-based <NAMED ENTITY>] can find Organization_Headquarter_Location() relations; but can also misclassify sentences such as "Florida Orange-based Heinz Marmalade". (See Snowball).
  - The [[Lexical_Relation_Recognition_Pattern?]] [<Class Noun>(plural) such as <Noun>, and <Noun>] can find Is_A() relations. (See [Hirst, 1994]).
