Abstract: A hybrid network 100 which combines a neural network of the self-organized type 110 with a plurality of neural networks of the supervised learning type 150,160,170 to successfully retrieve building address information from a database using imperfect textual retrieval keys. Generally, the self-organized type is a Kohonen Feature Map network, whereas each supervised learning type is a Back Propagation network. A user query 105 produces an activation response 111,112,113 from the self-organized network 110 and this response, along with a new query 151,161,171 derived from the original query 105, activates a selected one of the learning networks R.sub.1,R.sub.2,R.sub.M to retrieve the requested information.
