said knowledge base memory includes a first area for storing expertise in the field of the consultation and a second area for storing processing know-how relating to a processing of the consultation;

said inference engine includes a work memory for storing facts clarified in an inference process, status of a client, intention of the client, a reply to the client and progress status of the consultation;

said first area includes advice rules, each of which has a premise condition part and a reply generation part;

said premise condition part includes statements of the status of the client, the intention of the client, and the progress status of the consultation; and

said inference engine comprises means for selecting a reply in accordance with the status of the client, the intention and the progress status, and means for offering the selected reply to the client.

2. The computer system for consultation according to claim 1, wherein

said reply generation part includes questions for the client, and

said inference engine comprises means for selecting a question from said questions included in said reply generation part in accordance with the status of the intention of the client, and with the progressing status of the consultation.

3. The computer system for consultation according to claim 1, wherein

said first area includes definitions of terms in the consultation field, said second area includes processing for explaining a term, and

said inference engine includes means for inputting a command for requesting the explanation of one of the terms included in said first area and means for executing said processing for explaining a definition of the one term requested by the inputted command.

4. The computer system for consultation according to claim 1, wherein

said first area stores detailed explanation corresponding to the reply,

said second area includes processing for explaining in detail the reply, and

said inference engine includes means for inputting a command for requesting detailed explanation of the reply and means for executing said processing for explaining the reply in detail by using the detailed explanation stored in said first area, in response to the inputted command.

5. The computer system for consultation according to claim 1, wherein

said first area stores an example corresponding to the reply,

said second area includes processing for presenting said example to the reply, and

said inference engine includes means for inputting a command for requesting the example corresponding to the reply and means for executing said processing for presenting the example stored in the first area in response to said inputted command.

6. The computer system for consultation according to claim 1, wherein

said first area includes, hierarchically, the advice rules,

said second area includes processing for omitting another reply in accordance with another advice rule which is of the same group as another device rule executed just before, and

said inference engine includes means for inputting a command for requesting the switch of topics and means for executing said processing for omitting said another reply in accordance with said another advice rule, in response to said inputted command.

7. The computer system for consultation according to claim 1, wherein

said second area includes processing for printing the reply, and
