Table of contents
Description
Uses a dictionary to match entity mention text to a specific entity in Wikipedia.
For instance the text Hank Williams is matched to Hank Williams.
A useful example of this would be that both the strings FDR and Franklin Delano Roosevelt are mapped to the Franklin D. Roosevelt page.
The English WikiDict contains 20948089 mappings from Strings to entities.
