dc.description.abstractMUCH OF THE RESEARCH IN INFORMATION RETRIEVAL (IR) IS DEVOTED TO STUDYING THE IMPROVEMENT OF PERSONALIZED RESULTS FOR SPECIFIC USERS IN A STATIC ENVIRONMENT. NEVERTHELESS, FEW APPROACHES TAKE ADVANTAGE OF COLLECTIVE PAST SEARCHES IN A DYNAMIC CONTEXT WHERE THE NUMBER OF DOCUMENTS IS INCREASED ACCORDING WITH THE PASSAGE OF TIME. IN THIS PAPER, WE PRESENT AN ON-LINE PROBABILISTIC ALGORITHM, WHICH USES THE COLLECTIVE PAST SEARCHES IN A DYNAMIC CONTEXT TO ANSWER STATIC AND DYNAMIC QUERIES. SEVERAL EXPERIMENTS WERE CARRIED OUT WITH THE AIM OF EVALUATING THE EFFECTIVENESS OF OUR ALGORITHM. THE ALGORITHM S RESULTS WERE COMPARED WITH THE COSINE MEASURE. FOLLOWING THE CRANFIELD PARADIGM, SIMULATED DATASETS WERE USED IN THE EXPERIMENTS. FINAL RESULTS SHOW THAT IT IS POSSIBLE TO IMPROVE EFFECTIVENESS IN A DYNAMIC CONTEXT.
