Abstract
A named entity discriminating system capable of discriminating names entities such as location names, personal names, and organization names in text with a high degree of accuracy is provided. A reading means reads text from a hypertext database. A single text analyzing means analyzes each text read by the reading means and detects candidates for the named entity in the text. A complex text analyzing means estimates the likelihood of the candidate named entity detected by the single text analyzing means by an analysis with reference to referring link text or linked text of the text in which the candidate named entity appears.
