HYBRID SYSTEM FOR NAMED ENTITY RESOLUTION
First Claim
1. A method for named entity resolution comprising:
- parsing an input text string to identify a context in which an identified named entity of the input text string is used;
comparing the identified context with at least one stored context in which the named entity in the stored context is associated with a class of named entity, the named entity class being selected from a plurality of classes, at least one of the plurality of classes corresponding to a metonymic use of a respective named entity;
assigning a named entity class from the plurality of named entity classes to the identified named entity based on at least one of the identified context and the comparison.

Abstract
A method for named entity resolution includes parsing an input text string to identify a context in which an identified named entity of the input text string is used. The identified context is compared with at least one stored context in which the named entity in the stored context is associated with a class of named entity, the named entity class being selected from a plurality of classes, at least one of the plurality of classes corresponding to a metonymic use of a respective named entity. A named entity class is assigned to the identified named entity from the plurality of named entity classes, based on at least one of the identified context and the comparison.

16. A hybrid system for named entity resolution comprising:
-
a symbolic component for identifying a context in which an identified named entity of an input test string is used; and a distribution component for computing a distance between the identified context in which the named entity is being used and another context in which the named entity is used in a known metonymic sense; a data structure which stores a plurality of contexts; the system assigning a class to the identified named entity, based on at least one of the identified context and the computed distance. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)

24. A method for document annotation comprising:
-
inputting a document comprising at least one text string; parsing the text string to identify a context in which an identified named entity of the text string is used; comparing the identified context with at least one stored context in which the named entity in the stored context is associated with a class of named entity, the named entity class being selected from a plurality of classes, at least one of the plurality of classes corresponding to a metonymic use of a respective named entity; assigning a named entity class from the plurality of named entity classes to the identified named entity based on at least one of the identified context and the comparison; and annotating the document based on the assigned class. - View Dependent Claims (25)
