Complex Schema Mapping and Linking Data: Beyond Binary Predicates

Jacobo Rouces, Gerard de Melo, Katja Hose
2016 The Web Conference  
In this paper, we present a method for linking datasets that is expressive enough to support these cases. It consists of integration rules between arbitrary datasets and a mediated schema.  ...  Often, a relationship exists between an entity in one dataset and what is represented by a complex pattern in another, or between two complex patterns.  ...  Acknowledgments The research leading to these results has received funding from National Basic Research Program of China Grants 2011CBA00300, 2011CBA00301, and NSFC Grants 61033001, 61361136003, 61550110504  ...

Type-based data structure verification

Ming Kawaguchi, Patrick Rondon, Ranjit Jhala
2009 Proceedings of the 2009 ACM SIGPLAN conference on Programming language design and implementation - PLDI '09  
Our approach is based on the observation that complex data structures are typically fashioned from two elements: recursion (e.g., lists and trees), and maps (e.g., arrays and hash tables).  ...  We present a refinement type-based approach for the static verification of complex data structure invariants.  ...  We thank Robbie Findler and Amal Ahmed for valuable discussions about Polymorphic Refinements.  ...

Ontological Multidimensional Data Models and Contextual Data Qality [article]

Leopoldo Bertossi, Mostafa Milani
2017 arXiv   pre-print
The data under assessment is mapped into the context, for additional analysis, processing, and quality data extraction.  ...  The OMD model is interesting per se, beyond applications to data quality.  ...  An OMD model has a database schema R M = H ∪ R c , where H is a relational schema with multiple dimensions, with sets K of unary category predicates, and sets L of binary, child-parent predicates (cf.  ...

Formal Specification of a Data Dictionary for an Extended ER Data Model

V. Misic, D. Velasevic, B. Lazarevic
1992 Computer journal  
A formal definition of the data dictionary for an extended entity-relationship data model is described.  ...  Furthermore, a simple transformation of the extended ER schema to a relational one is formally described as well.  ...  Acknowledgements The authors gratefully acknowledge the comments of the anonymous reviewers, which considerably improved the readability of the paper, and the kind donation of the o z . s t y LATgX style  ...

Linked Data Integration with Conflicts [article]

Jan Michelfeit, Tomáš Knap, Martin Nečaský
2014 arXiv   pre-print
This paper explores Linked Data integration and its specifics.  ...  We focus on data fusion and conflict resolution: two novel algorithms for Linked Data fusion with provenance tracking and quality assessment of fused data are proposed.  ...  constructs a mapping to canonical URIs from input same-as links and ontology mappings in the first step which is used to resolve identifier and schema conflicts in the second step.  ...

The Typed Graph Model – a Supermodel for Model Management and Data Integration [article]

Fritz Laux
2021 arXiv   pre-print
It is difficult to ensure data quality for the properties and the data structure because the model does not need a schema.  ...  We illustrate by example the superiority of this model over the property graph data model of Hidders and other prevalent data models, namely the relational, object-oriented, XML model, and RDF Schema.  ...  Example RDFS (left part) to TGS (right part) mapping with complex predicates [17] J.

Managing scientific data: From data integration to scientific workflows* [chapter]

Bertram Ludäscher, Kai Lin, Shawn Bowers, Efrat Jaeger-Frank, Boyan Brodaric, Chaitan Baru
2006 Special Paper 397: Geoinformatics: Data to Knowledge  
Scientists are confronted with significant datamanagement problems due to the large volume and high complexity of scientific data.  ...  Such scenarios are not amenable to conventional schema-integration approaches.  ...  C ⊆ Σ P.1 (concepts), binary predicates R ⊆ Σ P.2 (roles, properties), and constants I ⊆ Σ F.0 (individuals).  ...

A Semantic Approach to Discovering Schema Mapping Expressions

Yuan An, Alex Borgida, Renee J. Miller, John Mylopoulos
2007 2007 IEEE 23rd International Conference on Data Engineering  
Thus, when mappings are realized as queries (as in data exchange), Skolem  ...  This relationship is expressed in terms of declarative logical expressions called schema mappings.  ...  The encoding uses unary predicates for classes, binary predicates for attributes, and binary predicates for binary relationships.  ...
