A human-centred design approach for developing dynamic decision support system based on knowledge discovery in databases

Combination of cognitive and HCI modeling for the design of KDD-based DSS used in dynamic situations

“…These activities help the users achieve their tasks of handling patient temporal data and dynamic decision-making to fight against NI. Table 8 shows that the overall performance is better than the results obtained in the two previous versions of our system presented in [3] and [54].…”

“…In fact, this topic has already been presented and discussed [3] and [54], and provided various applications to calculate the NI occurrence percentage using different data mining techniques. Although the preliminary results were promising, the cognitive load exerted by the physician to analyze, understand and take the appropriate decision is very high.…”

“…This process allows providing knowledge for decision-making in real time. The KDD-based Dynamic DSS may be considered as an interactive system [54] and the interactivity means a strong user involvement. In fact, the majority of research works in the KDD field focused on the development of efficient automatic algorithms.…”

Using visualization techniques in knowledge discovery process for decision making

“…These techniques must be integrated in the different modules of an existing KDD-based DSS for the fight against nosocomial infections [18].…”

“…• Tabular Representation Technique (TRT): allows a visualization of data sets in tabular form [19] • Perspective wall Technique (PWT): allows data to be presented chronologically on several panels (walls) [18] • Diagram Representation Technique (DT): allows representing quantitative data values compared to the corresponding temporal moments [8].…”
