Multi-Context Systems (MCS) are a powerful framework for interlinking possibly heterogeneous, autonomous knowledge bases, where information can be exchanged among knowledge bases by designated bridge rules with negation as failure. An acknowledged issue with MCS is inconsistency that arises due to the information exchange. To remedy this problem, inconsistency removal has been proposed in terms...

Background We aimed to conduct a systematic review and meta-analysis of RHR's efficiency safety, in addition comparison between open laparoscopic techniques. Methods A literature was conducted from 2000 2020 including studies reporting on their centre's outcomes for robotic hernial repairs. conducted. For continuous data, Mantel–Haenszel chi-squares test used inverse variance dichotomous data. ...

A repair of an inconsistent database is traditionally defined as a consistent database that differs from the inconsistent one in a “minimal way.” As there are often reasons to prefer one repair over another, researchers have introduced and investigated the framework of preferred repairs, where a priority relation between facts is lifted towards a priority relation between consistent databases, ...

In its traditional definition, a repair of an inconsistent database is a consistent database that differs from the inconsistent one in a “minimal way.” Often, repairs are not equally legitimate, as it is desired to prefer one over another; for example, one fact is regarded more reliable than another, or a more recent fact should be preferred to an earlier one. Motivated by these considerations,...

XML access control policies involving updates may contain security flaws, here called inconsistencies, in which a forbidden operation may be simulated by performing a sequence of allowed operations. This paper investigates the problem of deciding whether a policy is consistent, and if not, how its inconsistencies can be repaired. We consider policies expressed in terms of annotated DTDs definin...

The relationship between constraints on surface forms and operations that alter representations is of central interest in phonological theory. This squib presents a case of diverse “repairs” in response to a marked structure—labial . . . labial sequences—created by um-infixation in stems beginning with (or, in some cases, merely containing) labial consonants in Austronesian languages. We review...

This paper describes extensions of our previously proposed SW prototype – Analyzer, a framework for performing statistical analyses of real-world XML data. Firstly, it describes the design and implementation of a system for the analysis of collection of XQuery programs. It is based on the frequency of the occurrence of various language constructs and their combinations defined by the user. In t...

Data-cleaning (or data-repairing) is considered a crucial problem in many database-related tasks. It consists in making a database consistent with respect to a set of given constraints. In recent years, repairing methods have been proposed for several classes of constraints. However, these methods rely on ad hoc decisions and tend to hard-code the strategy to repair conflicting values. As a con...

In a multidimensional (MD) database, dimensions may be subject to semantic conditions that are not enforced by MD DBMSs or data warehouse applications. Strictness and homogeneity are possibly two of them; and are crucial for the efficiency and correctness of answering MD aggregate queries and updating materialized aggregate views. Dimensions may become inconsistent, i.e. non-strict or heterogen...
