# Ordering-Based Representations of Rational Inference

Rational inference relations were introduced by Lehmann and Magidor as the ideal systems for drawing conclusions from a conditional base. However, there has been no simple characterization of these relations, other than its original representation by preferential models. In this paper, we shall characterize them with a class of total preorders of formulas by improving and extending Gardenfors and Makinson's results for expectation inference relations. A second representation is applicationâ€¦Â

Relevance Sensitive Non-Monotonic Inference on Belief Sequences

The inference operation thus defined easily handles iterated revision by maintaining a revision history, blocks the derivation of inconsistent answers from a possibly inconsistent sequence and maintains the distinction between explicit and implicit beliefs.

Nonmonotonic Proof Systems: Algebraic Foundations

MAK triples and KLM triples are formed in ways similar to MAK models and K LM models but now on the algebraic structures for the nonmonotonic systems, thereby a new type of semantics is given to these systems.

A symbolic framework for representing domain knowledge in an adaptive information filtering agent is described and how the AGM belief revision paradigm can be applied to develop the agent's learning mechanism is illustrated.

Relevance as Deduction: A Logical View of Information Retrieval

- Computer ScienceArXiv
- 2000

This work introduces a simple but powerful logical framework of relevance feedback, derived from the well founded area of nonmonotonic logic, which claims that retrieval is a form of deduction.

A Logical approach to Query Reformulation motivated from Belief Change

- Computer Science
- 1999

It is argued that query expansion and query revision can be explained in terms of the revision of the user's beliefs in query terms as well as being under-pinned by a process of belief expansion.

Belief Revision and Default Reasoning: Syntax-Based Approaches

- Computer ScienceKR
- 1991

It is shown that a general form of syntax-based belief revision corresponds to a special kind of partial meet revision in the sense of variants of logics for default reasoning, which turns out to be located at the lower end of the polynomial hierarchy.
