Inference-Guiding On Bayesian Knowledge-Based Systems, Jinchang Wang
Inference-Guiding On Bayesian Knowledge-Based Systems, Jinchang Wang
Journal of International Technology and Information Management
Bayesian network is a robust structure for representing knowledge containing uncertainties in a knowledge-based system. In applications of expert systems and knowledge-based systems, it often happens that initial data are not sufficient to derive a conclusion of high enough certainty. Inference-guiding is in that case to identify the missing information, pursue its value, and lead inference to a conclusion. This paper presents and characterizes a criterion for effectively selecting key missing information, and thereby develops a “smart” inference approach with the inference-guiding function based on the newly developed criterion for uncertain inference in a Bayesian knowledge-based system.

Improving The Judicial System To Handle Computer Crime, Gerald V. Post, Albert Kagan
Journal of International Technology and Information Management
This paper asked professionals in the legal system to evaluate the current state and effectiveness of laws to identify and deter computer crime. Responses were evaluated with a formal structural equation model. The results generally show that legal professionals believe potential jurors have minimal knowledge of computer crime issues. More importantly, they also believe that judges have little knowledge or experience. A similar lack of knowledge by defense attorneys indicates that it could be difficult for a person accused of computer related infractions to find adequate representation. On the other hand, more experienced participants do not believe computer laws present …
