GeniMiner, un moteur de recherche génétique

We present in this paper a genetic search strategy for a search engine. We begin by showing that important relations exist between Web statistical studies, search engines based on agent approach, and standard techniques in optimization: the web is a graph which can be searched for relevant information with an evaluation function and with operators based on creation or local exploration. It is then straightforward to define an evaluation function that is a mathematical formulation of the user request and to define a steady state genetic algorithm that evolves a population of pages with specific operators. The creation of individuals is performed by querying standard search engines. The mutation operator consists in exploring the neighborhood of a page thanks to the hyperlinks. We present a comparative evaluation which is performed with the same protocol as used in optimization. MOTS-CLÉS : moteur de recherche, Internet, algorithmes génétiques, optimisation.
