Dove e quando

Seminario presso DIBRIS, sede di Valle Puggia Il giro di affari legato ai "click" sul web è enorme. Si va dalla pubblicità pay-per-click all'offerta commerciale personalizzata sui gusti individuali del singolo cliente. E con il crescere del fatturato, crescono anche le opportunità di frode... in questo caso spesso affidate ad utenti fasulli, i cositddetti web robot o "bot": sempre meno distinguibili da utenti umani, e responsabili di grandi percentuali dell'intero traffico su Internet, probabilmente vicine o superiori al 50%, anche se le stime sono ampiamente variabili. La sfida del "web usage mining" consiste nello studiare il comportamento degli utenti per migliorare il servizio, cercando allo stesso tempo di discriminare fra traffico spontaneo e click generati artificialmente. Title: Web usage mining in e-commerce environment Speaker: Grażyna Suchacka Speaker affiliation: Institute of Mathematics and Informatics, Opole University, Poland Date: mer 15-02-2017 2pm, DIBRIS Conference Room, third floor Valle Puggia building (Via Dodecaneso 35) Host: Stefano Rovetta Abstract: The presentation will concern the issue of analysis and modeling of usage data on e-commerce websites. First, the way of accessing Web sites by Internet users and type of data available on Web servers will be talked over, followed by a discussion on a specificity of e-commerce data. Then, some data mining (DM) tasks, methods and areas of application will be briefly presented. Two examples of application of DM methods to e-commerce data will be presented: detection of Web bots and prediction of purchases in Web user sessions.
