Knowledge Sources

• When developing software you need to figure out what the user needs.
• With knowledge based systems you also need to figure out what the user knows because your going to encode that knowledge in your system.
• Where can you get knowledge about a problem?
• Text books, reports, journal articles, case histories.
• Databases (datamining)
• However, for real systems (particularly ESs) these sources do not provide deep knowledge.
• For that you need Human Experts.
