The aim of this study is to analyse a set of data got through an on-line platform, using some ranking and knowledge oriented discovery rules techniques. Data mining techniques are applied to obtain a reliable relationship which can show the interest of the users in order to fill rigorously the on-line questionnaire attending to the way they do. Although there are programming techniques which allows us to observe the behaviour of users while filling the survey, current work uses artificial neural networks to predict their behaviour, based on variables obtained from the own survey. The sample is made up of 1,636 participants from different geographical areas and age ranges, obtained anonymously by answering the IPSETA questionnaire which is used for a psychological monitoring of sport talents. The results obtained using the analysis techniques show that females prefer to register on the platform to fill the survey, getting a high reliability (70%).
