Abstract | Investigates the consistency of different newspapers in their choice of words when writing about the same news events based on a study of three Finnish newspapers. Concludes that expression inconsistency is a sign of a retrieval problem and that query expansion based on semantic relationships can significantly improve retrieval performance on free text sources.
