Sobre IBD

Con la proliferazione delle architetture orientate ai servizi (SOA), il numero di servizi Web è aumentato drasticamente, rendendo difficile per gli utenti la selezione di un servizio pertinente. Il paradigma Skyline, che aiuta a selezionare i servizi Web in base ai dati sulla qualità del servizio (QoS), è diventato popolare presentando solo i servizi non dominati. Tuttavia, questo approccio presenta dei limiti, come la produzione di risultati incomparabili, l’attribuzione di un peso uguale a tutti i criteri QoS e l’impossibilità di controllare la dimensione dei risultati. Il primo, SkyAP-S3, combina metodi multicriteriali (MCDM) come Skyline e AHP per ponderare i criteri e PROMETHEE per integrare le preferenze degli utenti. Il secondo, SEFAP, migliora SkyAP-S3 gestendo l’incertezza nei giudizi degli utenti, utilizzando l’entropia e il Fuzzy AHP. Infine, viene proposta una versione avanzata di Fuzzy AHP per automatizzare il confronto di criteri e servizi attraverso un algoritmo di discretizzazione. Gli esperimenti condotti hanno dimostrato l’efficacia di questi approcci.
