Mercure includes the implementation of a retrieval process based on spreading activation forward and backward through the weighted links. Queries and documents can be either inputs or outputs of the network. The links between two l a yers are symmetric and their weights are based on the tf id f measure inspired from the OKAPI 4] t e r m w eighting formula.
