Unsupervised Discrimination and Labeling of Ambiguous Names
This paper describes adaptations of unsupervised word sense discrimination techniques to the problem of name discrimination. These methods cluster the contexts containing an ambiguous name, such that each cluster refers to a unique underlying person or place. We also present new techniques to assign meaningful labels to the discovered clusters.

متن کاملIdentification and Tracing of Ambiguous Names: Discriminative and Generative Approaches
A given entity – representing a person, a location or an organization – may be mentioned in text in multiple, ambiguous ways. Understanding natural language requires identifying whether different mentions of a name, within and across documents, represent the same entity. We present two machine learning approaches to this problem, which we call the “Robust Reading” problem. Our first approach is...
متن کاملSemantic Integration in Text: From Ambiguous Names to Identifiable Entities
senting, and manipulating correspondences between entities in disparate data sources. The topic has been widely studied in the context of structured data, with problems being considered including ontology and schema matching, matching relational tuples, and reconciling inconsistent data values. In recent years, however, semantic integration over text has also received increasing attention. This...
