Jahn/Herren MarianneData Quality for Decision Processes (Working Title)
by Marianne Jahn
primary goal is to sell GI products using an optimized sale
strategy. User requirements have to be researched to achieve
a reproducable decision making process. With this information it
is possible to adapt the implementation and determine whether to
generalize or to specify. Depending on the usage of the application,
usability for the user becomes predictable, which influences the choice
of used methods in the model. Legal and physical restrictions are
defined in the used ontology and must be considered to assess
usability, which helps in dealing with uncertainty and for basic
measurement. These three aspects define data quality from the user
point of view.
The resulting rules should be as simple as
possible to ease error specification and evaluation of consequences.
Based on the scenario of the one-way situation represented by
driving a car in a city, the impacts of the developed models are
verified. The required adaptations to the changed situation can
be offered to the customer as an extension to enhance user acceptance
of the application. The critical aspect is the definition of usability
for the user caused by the decision process, the resulting consequences
for data quality and the methods used in the application.
