2. Input data mining task on case retriever. The elements of data mining task have
been listed on case retriever. The user needs to set the values of these elements by
directly inputting or selecting from combo boxes.
3. Click “ Retrieve ” button on case retriever to retrieve similar case from DMCRL
repository. We assume there are enough cases stored in DMCRL repository. The
