1.11 A Simple Knowledge Base (KB)

1.11.1 Introduction

We can use the example of the Wumpus world to explain what a simple knowledge base might constitute. From figure 131, the agent has detected nothing in the state [1,1] and a breeze in the state [2,1]. These percepts, combined with the knowledge of the agent as regards the rules of the Wumpus world, constitute the Knowledge Base. The KB can be understood as a set or series of sentences or as a single sentence that asserts all the individual sentences. The KB is false or wrong in models that refute what the agent knows. For example, the KB is false in any model in which state [1,2] contains a pit since there is no breeze in the state [1,1] (Russell & Norwig, 2010, p. 241).
