Interactive system based on web search results clustering for Arabic query reformulation

The main goal of this work is to propose an Interactive System for Arabic Web Search Results Clustering ISAWSRC that may be used as helpful tool for Arabic Query Reformulation. This latter is an enhanced version of our published system called AWSRC for Arabic Web Search Results Clustering. Using this proposed interactive system, the user can decide at a glance whether the contents of a cluster are of interest: He/She does not have to reformulate the query, but can merely click on the produced cluster label most accurately describing his or her specific information need in the topic hierarchy. Therefore, the user can navigate in the sense of generalization or specification based on these cluster labels. To illustrate the efficiency and to evaluate the performance of our proposition, several experiments have been conducted. The obtained results show that: on the one hand the quality of the cluster labels is very high and can help user to reformulate his/ her queries, and on the other hand the generated topics hierarchy allow the user the possibility to navigate the sense of generalization and/or specialization without need of query reformulation.
