Consistency enforcement in medical knowledge base construction

Artificial Intelligence in Medicine, 1993
Some aspects of knowledge base creation can be partially or completely automated, resulting in higher quality and smaller effort. Computer assistance is particularly valuable in ensuring the internal consistency of a knowledge base. The article describes several techniques for consistency enforcement in QMR-KAT, an interactive knowledge base editor for

Database — Knowledge Base Consistency Monitor

1990
Expert systems composed of a database and a knowledge base, which cooperate, are considered. In such systems mutual consistency of the database and the knowledge base must be enforced. A consistency monitor is proposed for this purpose, whose task is double: to enforce internal consistency of the database and mutual consistency of the database and the ...

Rule-based consistency enforcement for knowledge-based systems

IEEE Transactions on Knowledge and Data Engineering, 1993
A rule-based approach for the automatic enforcement of consistency constraints is presented. In contrast to existing approaches that compile consistency checks into application programs, the approach centralizes consistency enforcement in a separate module called a knowledge-base management system.

ACQUA: Approximate Consistent Query Answering Over Inconsistent Knowledge Bases

2019 IEEE Second International Conference on Artificial Intelligence and Knowledge Engineering (AIKE), 2019
Consistent query answering is a principled approach for querying inconsistent knowledge bases. It relies on two central notions: a repair, that is, a maximal consistent subset of the facts in the knowledge base, and a consistent query answer, that is, a query answer entailed by every repair of the knowledge base.

Inductive consistency in knowledge-based decision support systems

Decision Support Systems, 1995
Abstract Efforts to integrate knowledge into Decision Support Systems have lead to approaches that incorporate induction techniques to derive rules from data. Such integration efforts create a new integrity control challenge for Knowledge-Based Decision Support Systems. The challenge is recognizing and coping with change.

Retaining Consistency for Knowledge-Based Security Testing

2014
Testing of software and systems requires a set of inputs to the system under test as well as test oracles for checking the correctness of the obtained output. In this paper we focus on test oracles within the domain of security testing, which require consistent knowledge of security policies.

Knowledge Base Maintenance and Consistency Checking in MOLTKE

2023
This paper deals with special problems of knowledge base maintenance which have to be solved within the knowledge acquisition process. We illustrate that aspects of maintenance must be taken into account by the design model construction because dependencies between pieces of knowledge can result in inconsistent states of a knowledge base. We describe a

Weight-based consistent query answering over inconsistent $${\mathcal {SHIQ}}$$ knowledge bases

Knowledge and Information Systems, 2012
Non-standard query mechanisms that work under inconsistency are required in some important description logic (DL)-based applications, including those involving an inconsistent DL knowledge base ( KB) whose intensional knowledge is consistent but is violated by its extensional knowledge.
