If formed mutual conversation by this sound can feel a human personifies with the support system.
(3) Customization function:
As for the support system, there is the necessity that a situation of the support changes into with real time. They must have a function to deal with confusion entering from environment to change every moment adequately. In addition, helped human ability and level are physiological and detect a state of mind one more and must aim at any time reasonable intellectual support activity.
In other words as while a human grows up, and support system oneself does autonomously learning the same pattern.
(4) Information joint ownership function:
The support system should have common share every information about operation of the engine with a human. For example, we have to check each other on the current running the main engine, how much rotating speed or output? Because a human shares all the necessary information with a support system, can confirm consciousness as a partner mutually. When there is a function to exchange greetings mutually, besides a confirmation by a sound, it advances in the good relation. Technical knowledge acquired by an expert chief engineer is expressed by form of "order ⇒ reply" mainly and they are collected and constitute knowledge base of CE-SYS.
4-3 Knowledge Representation
In the knowledge-based system, the knowledge representation is most important factors. In processing of computer, knowledge must be expressed with same uniformed representation. In addition, knowledge representation must be familiar for a user. The knowledge is changed into hierarchical structure that we will express the relation of individual knowledge adequately, and, furthermore, it is changed into a module, and it becomes change into a network. We can consider this case to be a divide by class of knowledge, but these knowledge structures extend with mechanism of reasoning deeply. Moreover, the opinion concerning the knowledge representation is more important than reasoning technique. It is hard to realize a high expert system of ability when the poor input knowledge even if how advanced reasoning technique is used. However, we can realize a high expert system of ability even if it takes the case of the good database, with simple reasoning technique. Nevertheless, when the working problem becomes complicated, knowledge to treat grows in large quantities, knowledge representation technique needs severely to manage and care the advanced knowledge system. Simultaneously it is necessary to can represent vagueness in automatically.
4-4 Knowledge Acquisition
Performance capacity of such a knowledge-based system depends on built knowledge itself. The knowledge acquisition, which has the technical knowledge of a problem territory of the marine engine operation, and builds the knowledge base, is very important.
