Patent Images
1. A method comprising:
- receiving one or more natural language dependency parse trees as input;
processing, using a hardware processor, the dependency parse trees by creating a mapping from nodes of the one or more dependency parse trees into actions, roles and contextual predicates; and
using the mapping for information extraction,wherein;
the actions comprise said verbs along with attributes of said verbs;
the roles comprise arguments for said verbs; and
the contextual predicates include modifiers for said verbs.

Abstract
A method includes receiving one or more natural language dependency parse trees as input. A hardware processor is used for processing the dependency parse trees by creating a mapping from nodes of the one or more dependency parse trees into actions, roles and contextual predicates. The mapping is used for information extraction. The actions include the verbs along with attributes of the verbs. The roles include arguments for the verbs. The contextual predicates include modifiers for the verbs.

9. A computer program product for information extraction via semantic abstraction, the computer program product comprising a computer readable storage medium having program code embodied therewith, the program code readable/executable by a processor to:
-
receive one or more natural language dependency parse trees as input; process, using the processor, the dependency parse trees by creating a mapping from nodes of the one or more dependency parse trees into actions, roles and contextual predicates; and using the mapping for extracting information, wherein; the actions comprise said verbs along with attributes of said verbs; the roles comprise arguments for said verbs; and the contextual predicates include modifiers for said verbs. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A system comprising:
-
a processor; a storage device coupled to the processor, wherein the storage device stores one or more text files; a parser that parses text into one or more natural language dependency parse trees; an action process that uses the processor for processing the dependency parse trees by creating a mapping from nodes of the one or more dependency parse trees into actions, roles and contextual predicates, wherein; the mapping is used for information extraction; the actions comprise said verbs along with attributes of said verbs; the roles comprise arguments for said verbs; and the contextual predicates include modifiers for said verbs. - View Dependent Claims (18, 19, 20)
