“…A second innovative aspect of our work is represented by the use of both expert knowledge and patient data to estimate the quantitative part of the probabilistic network. This approach is quite uncommon in the literature, where only one of the two sources of information is typically exploited (Andreassen et al, 1991;Charitos et al, 2009;Galán et al, 2002;Kline et al, 2005;Lacave & Díez, 2003;Leibovici et al, 2007;Luciani et al, 2007;Middleton et al, 1991;Nathwani et al, 1997;Suojanen et al, 1999;Van der Gaag et al, 2002). Applications where both expert knowledge and collected data are exploited include the expert systems DIAVAL (Díez et al, 1997) and HEPAR II (Wasyluk et al, 2001).…”

“…In prominent medical applications of probabilistic networks (Andreassen et al., ; Charitos et al., ; Díez et al., ; Galán et al., ; Kline et al., ; Lacave & Díez, ; Leibovici et al., ; Luciani et al., ; Middleton et al., ; Nathwani et al., ; Suojanen et al., ; Van der Gaag et al., ; Wasyluk et al., ), continuous variables were discretized in order to obtain a Bayesian network. The major benefits of a Bayesian network consist of a very intuitive parameterization (parameters are conditional probabilities) and the availability of fast algorithms for evidence propagation (see, e.g., Yuan & Druzdzel, ).…”

“…Existen experiencias semeTabla I. Rasgos y diagnósticos ofrecidos en la plantilla para efectuar la prueba. jantes de sistemas que usan imágenes como complemento pedagógico a las lesiones y diagnósticos [5,10]. Una primera consideración ha de ser que la prueba en sí, independientemente de si el alumno usó el sistema experto o pertenecía al grupo control, incidió positivamente en la adquisición de conocimientos (37,5% de aciertos en el test previo frente al 77,67% de aciertos en el test posterior: 62,5% para los que no usaron el sistema experto y 92,85% para los que sí lo usaron).…”

“…Es un proceso hipotético-deductivo. En la actualidad, se dispone de algunos sistemas orientados al diagnóstico, diseña-dos mediante diálogos interactivos [2][3][4][5][6][7].Los autores han desarrollado un sistema experto de ayuda al diagnóstico de la citología cervicovaginal [8]. Este sistema se ha construido en base a experiencias previas [6,8].…”
