# Can you use Knowledge Explorer?

## I envision five classes of KE users:

### 1. Personal computer owners

Every owner can use KE as a personal relational database management system. Compared to commercially available DBMSs, KE has the advantage of being more flexible and powerful -- you can dynamically redefine the knowledge base using simple English-like statements. Its "smart input menu" and "question"s provide simple form-based input and output.

### 2. Programmers

People with some programming background will find KE even more appealing because of its UNIX-like control structures. My knowledge representation language, KR, provides the essential features of a modern programming language.

### 3. Database designers

Database designers can use KE to explore and define the entity-relation model for a database system.

### 4. Professional philosophers

Philosophers can use KE as an aid in abstract thinking. Because the design of the KR language is based on a comprehensive theory of knowledge, it can concisely characterize anything from the most abstract axiomatic concepts to every day events.

### 5. Artificial Intelligence researchers

Because of KR's strong theoretical foundation, AI researchers can use KE to gain insight into basic knowledge representation issues.
