Improving ranking of webpages using user behaviour, a Genetic algorithm approach

Information retrieval has taken an important turn when the researchers started using user behavior to improve their ranking algorithms. With the advent of user behavior in information retrieval, the interactive information retrieval is beginning to make its mark. In this paper we discuss how user behavior is being used in information retrieval. We survey various strategies used for incorporating user behavior into information retrieval. A Genetic Algorithm is used in this paper to improve the average MAP score and ultimately a Select Best Ones (SBO) principle is used to arrive at the final ranking.
