generating keywords related to the classified task received from the TCU, though it works as a look-up table implemented using ANN technique.
• Hybrid Rule-Based System (HRBS): HRBS applies simple rules on the agent's knowledge domain, using the keywords, which are generated from NNAM, to infer the actual information required in executing the user's task.
In order to be able to assist users, an agent must be provided with knowledge of its domain.
