Answer:
d. Knowledge refinement subsystem
Explanation:
One of the biggest problems in companies today, whether large or small, is the use of knowledge that is constantly generated through all its processes and all its staff. This difficulty of using the knowledge of the company arises because the sources of it are very varied and range from documents to databases, discussion groups and people themselves.
The component that is in contact with the direct source of knowledge is the knowledge acquisition subsystem and for this same reason represents one of the largest bottlenecks in organizations. Many times it is not just an expert but a group of them who are responsible for developing the system and "emptying" their knowledge in the base. There are many tools and methods to obtain this knowledge among which is the interview, the observation and the creation of scenarios.
With the knowledge acquisition subsystem and the knowledge base ready, other processes must be followed to achieve the elaboration of the rules, the interface with the user and the inference mechanisms, however, the purpose of this article is to highlight the importance of the knowledge acquisition process, since it is the initial step in the development of an expert system and lays the foundation for its proper functioning.
