## Question

Differentiate between knowledge management (KM) and knowledge based expert systems.

## Short answer

Knowledge management is an organizational process of creating, capturing, storing, sharing and applying tacit and explicit knowledge, with people central. An expert system is a narrow-domain program with codified rules, facts and an inference engine that gives expert-level advice. An expert system can be a tool within KM.

## Answer

**Knowledge Management (KM)** is the organised process of creating, capturing, storing, sharing and applying the knowledge (explicit and tacit) of people across an organization. A **knowledge-based expert system (ES)** is a program that stores an expert's knowledge as rules and facts in a specific domain and uses an inference engine to give advice or solve problems like a human expert.

| Basis | Knowledge Management | Expert System |
|---|---|---|
| Aim | Share and reuse organizational knowledge | Give expert-level advice/decisions |
| Scope | Broad, whole organization | Narrow, one domain |
| Knowledge type | Tacit and explicit, documents, experience | Codified rules and facts |
| Human role | People remain central; collaboration | Replaces or assists the expert |
| Technology | Repositories, portals, wikis, search, communities | Knowledge base, inference engine, rule-based AI |
| Output | Access to knowledge and experts | A conclusion or recommendation |
| Reasoning | None by system | Automatic inference |
| Example | Company wiki, lessons-learned database | MYCIN medical diagnosis, loan advisor |

An expert system can be one tool within a KM system.

## Check yourself

The answer's key points as multiple-choice questions, with the correct option and why.

1. How does the scope of KM compare with that of an expert system?
   A. KM is narrow (one domain); ES is broad (whole organization)
   B. KM is broad (whole organization); ES is narrow (one domain)
   C. Both cover the whole organization
   D. Both are limited to one domain
   Answer: B. KM covers organization-wide knowledge, while an expert system is limited to a specific domain. (Key point: Scope)

2. Which knowledge does an expert system mainly use, compared with KM?
   A. Codified rules and facts, whereas KM handles tacit and explicit knowledge
   B. Only tacit knowledge in people's heads
   C. Only documents and wikis
   D. Informal experience with no codification
   Answer: A. An ES stores codified rules and facts; KM handles both tacit and explicit knowledge. (Key point: Knowledge type)

3. What differentiates the output/reasoning of an expert system from KM?
   A. KM performs automatic inference; ES gives only document access
   B. ES uses an inference engine to give a conclusion or recommendation, while KM does no reasoning itself and gives access to knowledge and experts
   C. Neither produces any output
   D. Both use inference engines equally
   Answer: B. An expert system infers automatically and recommends; KM provides access to knowledge and experts without system reasoning. (Key point: Reasoning and output)
