Question

1. Give a brief summary comparing the rule-based and preprocessor-based approaches with an emphasis on identifying any strengths or weaknesses associated with each approach.

Answer 1

Comparision:

1. For rule based approach you need a domain expert to define the set of rules while for preprocessing based approach you dont need a a domain expert.
2. RB approach dose not need large amount of data. Preprocessor may need huge data.
3. RB is often good for giving a frst cut solution to a problem.
4. RB requires a lot of manual work as compared to Preprocessor based approach.
5. In RB the system will generate results as per the rules set initially ,Preprocessor hence proves to be better in this aspect as there is no rules to generate/predict the result.
6. RB can all be time consuming as compared to the Preprocessor based approach. Imagine defining a rule base for a verry complex problem.
