A Knowledge Consistency: Useful Suspension of Disbelief*
نویسنده
چکیده
The study of knowledge is of great use in distributed computer systems. It has led to bet ter understanding of existing algorithms for such systems, as well as the development of new knowledge-based algorithm.~. The ability to achieve certain states of knowledge (e.g., common knowledge) provides a powerful tool for designing such algorithms. Unfortunately, it has been shown that for many systems it is impossible to achieve these states of knowledge. In this paper we consider alternative interpretations of knowledge under which these states can be achieved. We explore the notion of consistent interpretations, and show how they can be used to circumvent the known impossibility results in a number of cases. This may lead to greater applicability of knowledge-based algorithms. *Partial support for this work was provided by the National Science Foundation under grant DCR8601864.

Suspension of Disbelief in Interactive Information Retrieval Evaluation
In literature and art, suspension of disbelief is the willingness of the audience to accept a premise as true even if it is not possible in the real world. Audience members must set-aside their beliefs about the world and accept one or more premises which form the foundation for the new world. Research also requires a suspension of disbelief, especially research conducted in the laboratory. In ...

If autonomous agents interact with people, they should achieve the suspension of disbelief in order to offer a good interaction experience to users. To achieve this it is important that the agents’ behaviours are consistent with a given personality since people have a tendency to attribute personality to interactive artifacts. The concept of personality is also useful to create diversity in mul...
