Automatic query expansion technique has been extensively used in a variety of information retrieval (IR) systems as a means of solving the problems of information overload and word mismatch. Based on the technique and Hopfield network, we propose a new IR model, called LCA-ANN model. With the heuristic function of Hopfield network, the new model is more precise in query expansion compared with other current models and can therefore enhance the performance greatly.
