The productions form rules for constructing hierarchical data of a structured electronic document. The first group is associated with a first group of events, each production being defined for an event type and contextual information including a name associated with an element in the hierarchical data. The second group is associated with a second group of events distinct from the first group of events, the events of the second group describing the hierarchical data of the structured electronic document. The device determines whether an event is of the first group including determining whether the event in question is defined by a name associated with an element in addition to an event type, and predicts a production from the second group that is associated with the event is determined to be of the first group."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for accessing a production forming a set of rules for constructing hierarchical data of a structured document","description":"A method and apparatus access a production among first and second groups of productions.
