Reasoning on Spatial Semantic Integrity Constraints

by Stephan Mäs - COSIT 2007. LNCS , 2007
"... Abstract. Semantic integrity constraints specify relations between entity classes. These relations must hold to ensure that the data conforms to the semantics intended by the data model. For spatial data many semantic integrity constraints are based on spatial properties like topological or metric r ..."

Semantic Integrity Constraints for Spatial Databases

by Loreto Bravo, M. Andrea Rodríguez
"... Abstract. This paper introduces a formalization of a set of spatial semantic integrity constraints on an extended-relational database model. The formalization extends traditional notions of functional and inclusion dependencies by adding interaction with spatial attributes. This enables to specify i ..."

Semantic Integrity Constraint Checking for Multiple XML Databases

by Praveen Madiraju, Rajshekhar Sunderraman, Shamkant B. Navathe, Haibin Wang - Proceedings of 14th Workshop on Information Technology and Systems (WITS 2004), Washington D.C , 2004
"... Global semantic integrity constraints ensure integrity and consistency of data spanning multiple databases. In this paper, we take initial steps towards representing global semantic integrity constraints for XML databases. We also provide a general framework for checking global semantic integrity co ..."

Checking the Integrity of Spatial Semantic Integrity Constraints ∗

by Stephan Mäs
"... Abstract. Integrity constraints play a major role when the quality of spatial data is checked by automatic procedures. Nevertheless the possibilities of checking the internal consistency of the integrity constraints themselves are hardly researched yet. This work analyses the applicability of reason ..."
Abstract - Add to MetaCart
of reasoning techniques like the composition of spatial relations and constraint satisfaction in networks of relations to find conflicts and redundancies in sets of spatial semantic integrity constraints. These integrity rules specify relations among entity classes. Such relations must hold to ensure

Harmonisation of Spatial Semantic Integrity Constraints

by Stephan Mäs , 2009
"... As part of the quality description of a spatial data set logical consistency is very important to support interoperability between different systems. Logical consistency specifies “the degree of adherence to logical rules of data structure, attribution and relationships ” [1]. For the evaluation of ..."

Checking Semantic Integrity Constraints on Integrated Web Documents

by Franz Weitl, Burkhard Freitag - PROCEEDINGS OF THE COMWIM INTERNATIONAL WORKSHOP ON CONCEPTUAL MODEL-DIRECTED WEB INFORMATION INTEGRATION AND MINING, SHANGHAI, SPRINGER-VERLAG , 2004
"... A conceptual framework for the specification and verification of constraints on the content and narrative structure of documents is proposed. As a specification formalism we define CTLDL which is a new version of the temporal logic CTL extended with description logic concepts. In contrast to existin ..."
Abstract - Cited by 2 (0 self) - Add to MetaCart
to existing solutions our approach allows for the integration of ontologies to achieve interoperability and abstraction from implementation aspects of documents. This makes it specifically suitable for the integration of heterogenous and distributed information resources in the semantic web.

SEMANTIC INTEGRITY CONSTRAINT VIOLATIONS CHECK FOR SPATIAL DATABASE UPDATING

by K. P. Udagepola A, L. Xiang B, A. W. Wijeratne C, Y. Xiaozong A
"... An efficient spatial data structure in a GIS system for database updating is required in order to minimising of spatial constraint violations and timesaving. An automated constraint checking procedure has been introduced to perform constraint violations check at compiling time before updating the da ..."

A data structure called Semantic Spatial Outlier R-Tree (SSR O-Tree) was proposed for the Semantic Integrity

Compiling a Declarative High-Level Language for Semantic Integrity Constraints

by Suzanne M. Embury, Peter M. D. Gray - Proceedings of 6th IFIP TC-2 Working Conference on Data Semantics , 1995
"... The provision of more intelligent support for complex database applications is becoming an important research topic, and declaratively stated integrity constraints are increasingly being seen as a potential source of semantic information for such advanced DBMS's. However, despite much research ..."

Semantic Integrity Constraint Rule Discovery and Outlier Detection in Relational Data as a Data Quality Mining Technique

by R. Vasanth, Kumar Mehta, Enathur Kanchipuram, S. Rajalakshmi, Enathur Kanchipuram
"... Data Quality is critical to the quality of patterns and analysis obtained from data. One of the important factors plaguing data is violation of Semantic Integrity, leading to inconsistency, in turn resulting in generation of bad patterns or reports when data mining or warehousing techniques are appl ..."

are applied on such data. In this paper, a data quality mining technique is proposed to automatically generate Semantic Integrity Constraint Rules from the data. Further, this process leads to identification of Outliers, which are then to be classified as either violations or genuine cases of exception

Integrating Semantic Integrity Constraints into an Object-Oriented Database Management System: A Pragmatic Approach

by Olaf Zukunft, Heinrich Jasper , 1993
"... Although object-oriented data models provide rich language constructs for modelling the domain of discourse, there is a need for additional features in order to restrict the database to legal states. Such language extensions should fit naturally into the formalisms of the data model and should respe ..."
Abstract - Add to MetaCart

The proposed language does not only obey the principles of object-orientation but additionally is inherently conform to the new structural concepts of object-oriented database systems. We proved
