The size of a revised knowledge base
1999
Artificial Intelligence
Preserved Fulltext
In particular, we focus on the size of the smallest formula equivalent to the revised knowledge base. ...
In this paper we address a specific computational aspect of belief revision: The size of the propositional formula obtained by means of the revision of a formula with a new one. ...
Another issue that we want to address is the increase of the size of a revised knowledge base when this is composed with a series of revisions, not only one. ...

When the Dalal's revision operator is chosen, the revision-based approach is independent of the syntactic form in each stratum and it captures some notion of minimal change. ...
Two particular revision operators are considered, one is the Dalal's revision operator, which is a model-based revision operator, and the other is the cardinality-maximal based revision operator, which ...

We also strengthen some of the results by Cadoli, Donini, by showing that for some of the so called model based operators, a polynomial size representation does not exist even if we allow the new knowledge ...
In this paper, following the approach of Gocic, Kautz, Papadimitriou and Selman (1995) , we consider the ability of belief revision operators to succinctly represent a certain set of models. ...
I am grateful to Marco Cadoli for introducing me to the area of knowledge compilation and for several useful discussions. ...

From a practical standpoint, footprint size reduction provides a unified way of estimating the impact of a given piece of knowledge in any knowledge container, and can also suggest ways of characterizing ...
Case-Based Reasoning provides a framework for integrating domain knowledge with data in the form of four knowledge containers namely Case base, Vocabulary, Similarity and Adaptation. ...
Approach Footprint Size as a Unit of Knowledge In our work, we hypothesize that knowledge contained in a case base is only as good as the knowledge contained in its footprint cases. ...

Our approach consists in analysing the system execution logs and revising knowledge based on these logs by modelling the revision problem as a knowledge space exploration problem. ...
The objective of the work presented in this paper is to propose an automatic knowledge revision approach for systems based on an informed tree search strategy. ...
The "expert" knowledge base revision corresponds to the classical scenario of knowledge revision where we have a good initial rule base that we want to refine. ...

First, the knowledge base must contain the information necessary to fill the optional schema slot. Second, the inclusion of the additional knowledge must pass a test for salience. ...

This article presents such a framework by (1) refining and updating the earlier framework of dimensions for case-base maintenance, (2) applying the refined dimensions to the entire range of knowledge containers ...
The result is a framework for understanding the general problem of case-based reasoner maintenance (CBRM). ...
Data collection about the case base as a whole could involve, for example, monitoring the size of the case base. ...

Therefore, a combination of several formalisms on which revision operations are defined, is required for knowledge representation of such a hybrid system. ...
In this paper, we will introduce several revision policies in DL-based knowledge bases and show how revision operators are computed for DL language ALE. ...
On the other hand, since the definition of a concept in knowledge base can be modified by the application of a revision production rule, revision operations must be defined on DL-based terminology. ...

Our approach allows to revise the knowledge off-line by means of experiments. It is based on the analysis of solved instances of the considered problem and on the exploration of the knowledge space. ...
Indeed, we formulate the revision problem as a search problem: we search the knowledge set that maximises the performances of the system on a sample of problem instances. ...
