 Title: Enhancing Information Retrieval by Using Evolution Strategies Authors: Abdelmgeid Amin, Aly Keywords: Information Retrievalevolution strategy Issue Date: 2008 Publisher: Institute of Information Theories and Applications FOI ITHEA Abstract: Similar to Genetic algorithm, Evolution strategy is a process of continuous reproduction, trial and selection. Each new generation is an improvement on the one that went before. This paper presents two different proposals based on the vector space model (VSM) as a traditional model in information Retrieval (TIR). The first uses evolution strategy (ES). The second uses the document centroid (DC) in query expansion technique. Then the results are compared; it was noticed that ES technique is more efficient than the other methods.
