## Rule-Based System Architecture 4. Fuzzy inference systems Computer Science Department. We saw in Sections 7.1 and 7.2 how valid argument forms may be used as rules of inference in natural deduction. Forms of logical equivalences may also be used as rules of inference., Inference Problems in Multilevel Secure Database Management Systems Sushil Jajodia and Catherine Meadows An inference channel in a database is a means by which one can infer data classified at a high level from data classified at a low level. The in-ference problem is the problem of detecting and removing inference chan-nels. It is clear that inference problems are of vital interest вЂ¦.
