Unsupervised on-the-fly named entity resolution in dynamic corpora

Abstract:

A method for providing unsupervised entity resolution to a natural language processing system includes receiving a named entity for training from the natural language processing system, searching a corpus for a first undisambiguated named entity corresponding to the named entity, identifying a plurality of disambiguated named entities corresponding to the first undisambiguated named entity, identifying a plurality of aliases for each of the disambiguated named entities, training a classifier for the each of the disambiguated named entities utilizing the aliases identified for respective ones of the disambiguated named entities using the corpus, and resolving the named entity using the classifier, wherein resolving the named entity comprises selecting one of the disambiguated named entities from among the disambiguated named entities and returning, automatically, the selected disambiguated named entity to the natural language processing system.
