T-UCK: The User-Centred Knowledge Model

The paper presents a User-Centred Knowledge (t-UCK) model for consulting and disseminating knowledge by modelling knowledge, reasoning strategies and other functionality in systems, like knowledge-management systems. The quality of system's contents is of decisive importance for making good decisions. Models are needed to assure that required knowledge is present without introducing validation or verification problems. Current models tend to be large, presenting problems with knowledge comprehension. Moreover, some models are difficult to employ and apply correctly without expertise. To minimise these problems, t-UCK supports different users to identify, create, model, implement and test knowledge directly into systems through UML diagrams.
