....tuned. The next two sections present approaches which modify the document representation. 2. 3 Neural networks Neural networks are widely used in machine learning tasks and several authors have developed explicit networks for retrieval, e.g. the PIRCS system (Kwok [14, 15] and the work of Belew [4]. These models share the same basic characteristics. When a query is presented to the system, individual nodes that represent the query are activated (with varying intensity) Then this initial activation spreads through the network before activating the document nodes. The most highly stimulated ....
