Is your Schema Good Enough to Answer my Query? [article]

Yuanwei Zhao, Lan Huang, Bo Wang, Dongxu Zhang, Simone Bocca, Fausto Giunchiglia, Rui Zhang
2021 arXiv   pre-print
This paper studies the semantic similarity of schemas from the aspect of properties.  ...  It provides a set of in-depth criteria, namely coverage and flexibility to evaluate the compatibility among the queries, the schemas and the existing ontology.  ...  This paper proposes a property based semantic similarity criteria to evaluate the overlaps of schemas. By property, we mean the attribute in the database schema to represent the entity type.  ...

MuMIe: Multi-level Metadata Mapping System

Samir Amir, Ioan Marius Bilasco, Chabane Djeraba
2011 Journal of Multimedia  
The recent growth of multimedia requires an extensive use of metadata for their management. However, a uniform access to metadata is necessary in order to take advantage of them.  ...  Moreover, the proposed matching process makes use of several types of information (linguistic, semantic and structural) in a manner that increases the matching accuracy.  ...  Concerning the languages based on taxonomy classification (e.g., XML Schema), we use the idea proposed in [23] to capture the semantics of implicit properties.  ...

Ontology Mapping and Merging Aspects in Semantic Web

Gagandeep Singh Narula
2018 International Robotics & Automation Journal  
To build vocabulary it requires mapping and merging of ontologies from heterogeneous sources of data.  ...  The varied available tools automate integration, unification, aligning and merging of varied related ontologies.  ...  Deals with data schema and global virtual schema in which latter one consists of mapping descriptions to perform semantic mapping between global and data schema. b.  ...

LinksB2N: Automatic Data Integration for the Semantic Web [chapter]

Manuel Salvadores, Gianluca Correndo, Bene Rodriguez-Castro, Nicholas Gibbins, John Darlington, Nigel R. Shadbolt
2009 Lecture Notes in Computer Science  
The ongoing trend towards open data embraced by the Semantic Web has started to produce a large number of data sources.  ...  The algorithm relies on a novel approach that uses clustering techniques to analyze the distribution of unique objects that contain overlapping information in different data graphs.  ...  The algorithm evaluates each RDF property linked to a typed RDF resource 3 and clusters its values based on their similarity.  ...

Toward Generic Consistency Patterns in Multi-View Enterprise modelling

Afef Awadid, Dominik Bork, Dimitris Karagiannis, Selmin Nurcan
2018 European Conference on Information Systems  
This paper explores enterprise modelling methods with a focus on multi-view consistency, thereby contributing a thorough investigation of the syntactic and semantic overlaps between views.  ...  It then abstracts from concrete examples to derive generic consistency patterns which can be specified in a novel formalism. Utility of the formalism is evaluated in two case study applications.  ...  All consistency pattern criteria are independent from each other, therefore similarity needs to be analysed independently for all of them.  ...

Semantics of Distinguishing Criteria: from Subjective to Intersubjective

Martin Takac, Jan Sefranek
2012 Interdisciplinary Description of Complex Systems  
The resulting construction is based on a projection of the environment into a cluster of current percepts and a similarity function on percepts.  ...  An ability of cognitive agents to distinguish is a starting point of our approach, distinguishing criteria and schemata are the basic semantic constructs.  ...  ACKNOWLEDGMENTS We are grateful to Pavel Cmorej for his insightful comments on our semantics.  ...

Shadow Theory, data model design for data integration [article]

Jason T. Liu
2012 arXiv   pre-print
It is based on the notion of shadows in Plato's Allegory of the Cave.  ...  For data integration in information ecosystems, semantic heterogeneity is a known difficulty. In this paper, we propose Shadow Theory as the philosophical foundation to address this issue.  ...  The advantage of using overlapped areas to represent similarity is that it provides data integrators a way to evaluate similarity based on meanings in the context of different business semantics, like  ...

Towards a semantics-based approach in the development of geographic portals

Nikolaos Athanasis, Kostas Kalabokidis, Michail Vaitis, Nikolaos Soulakellis
2009 Computers & Geosciences  
Based on the Semantic Web, our approach exploits the Resource Description Framework (RDF) in order to describe the geoportal's information with ontology-based metadata.  ...  New metadata descriptions are published in the geoportal according to the RDF schemas.  ...  similar RQL query is evaluated.  ...

TableNet: An Approach for Determining Fine-grained Relations for Wikipedia Tables [article]

Besnik Fetahu, Avishek Anand, Maria Koutraki
2019 arXiv   pre-print
Determining the relation type of a table pair is not trivial, as it is dependent on the schemas, the values therein, and the semantic overlap of the cell values in the corresponding tables.  ...  TableNet consists of two main steps: (i) for any source table we provide an efficient algorithm to find all candidate related tables with high coverage, and (ii) a neural based approach, which takes into  ...  We consider a conjunction of filtering criteria based on empirically evaluated thresholds for the individual features.  ...
