Just as data mining techniques provide researchers with an automated method of gleaning unsuspected knowledge from structured electronic data (databases), parallel techniques are being developed to detect patterns and connections in unstructured electronic data (email, documents, websites). Text mining is in its infancy, but it offers hope for conquering the growing knowledge glut.
