Abstract

Official abstract text for this publication.

A classifier that disambiguates among entities based on a dictionary, such as corpus of documents about those entities, is built by incorporating probabilities that an entity exists that is not in the dictionary. Given a document it is associated by the classifier with an entity. By incorporating out of collection probabilities into the classifier, a higher level of confidence in the match between an entity and a document is achieved.

First claim

Opening claim text (preview).

What is claimed is: 1. A computer-implemented process for building a classifier for associating an entity with a document, comprising: accessing a dictionary that maps entities to related terms; partitioning the dictionary by entity names to provide a set of partitions, each partition relating to an entity name; estimating, for a partition, a probability that is a function of a. a probability that an entity has the entity name related to the partition and b. an estimated size…
