In the backward chaining technique, used by the inference engine component of an expert system, the expert system starts with the goal, which is the _____ part, and backtracks to find the right solution.

In the context of an expert system, explain the factual knowledge component of a knowledge base with an example.

In the context of the components of a typical expert system, _____ is a software package with manual or automated methods for acquiring and incorporating new rules and facts so that the expert system is capable of growth. ​

The size and complexity of the human language has made developing _____ difficult.
