Providing Alternative Declarative Descriptions for Entity Sets Using Parallel Concept Lattices [chapter]

Thomas Gottron, Ansgar Scherp, Stefan Scheglmann
2014 Lecture Notes in Computer Science  
We propose an approach for modifying a declarative description of a set of entities (e.g., a SPARQL query) for the purpose of finding alternative declarative descriptions for the entities.  ...  Our approach is based on the construction of parallel formal concept lattices over different sets of attributes for the same entities.  ...  Using Parallel Lattices to Derive Alternative Descriptions We now present our idea of building parallel concept lattices and how to exploit mappings between theses lattices for finding alternative descriptions  ...

Relational concept discovery in structured datasets

M. Huchard, M. Rouane Hacene, C. Roume, P. Valtchev
2007 Annals of Mathematics and Artificial Intelligence  
The borders for the application of the relational mining task are provided by what we call a relational context family, a set of binary data tables representing individuals of various sorts (e.g., human  ...  We present a method for constructing concepts on top of circular descriptions which is based on an iterative approximation of the final solution.  ...  The former two get credits for the experimental results as well.  ...

On "zero" and semantic plurality

Lisa Bylinina, Rick Nouwen
2018 Glossa  
We conclude that the fact that languages allow ascription of zero quantity to an entity provides evidence that linguistic semantics has access to what at first sight may seem like an ontological oddity  ...  : an entity with zero quantity.  ...  Acknowledgements The research leading to these results has received funding from the Netherlands Organisation for Scientific Research/VENI Grant no. 275-70-045 (first author) and the European Research  ...

We have found that there are two types of knowledge involved in software development: (1) descriptive knowledge represented by conversion and coding rules, e.g., a rule for splitting a class into two;  ...  In this research we focus on understanding the nature of the knowledge used during the various phases of the software development process.  ...  As with XML, the RDF data model provides no mechanisms for declaring property names that are to be used.  ...

On Using Conceptual Modeling for Ontologies [chapter]

S. Spaccapietra, C. Parent, C. Vangenot, N. Cullot
2004 Lecture Notes in Computer Science  
Are database concepts and techniques suitable for ontology design and management? The question has been on the floor for some time already.  ...  This paper analyzes some of the arguments that are relevant to the debate, in particular the question whether conceptual data models would adequately support the design and use of ontologies.  ...  Alternatives for the description of these mappings are well documented in the literature.  ...

Generating and Comparing Models within an Ontology

Trent Apted, Judy Kay
2002 Australasian Document Computing Symposium  
An ontology is useful for providing a conceptually concise basis for developing and communicating knowledge.  ...  The entity might be a document such as an email message, a course description document or a biography. It is intended to give a measure of the similarity of any two such models.  ...  Another similar project, [13] , also uses lattices for inferring user interests. However, it uses the lattices as a basis for interacting with the user to elicit an expanded self-description.  ...

Using SPARQL to Test for Lattices: Application to Quality Assurance in Biomedical Ontologies [chapter]

Guo-Qiang Zhang, Olivier Bodenreider
2010 Lecture Notes in Computer Science  
RDF, SPARQL and related tooling provide an eAEcient platform for implementing lattice algorithms on large data structures.  ...  The use case for this work is quality assurance in biomedical ontologies, one desirable property of which is conformance to lattice structures.  ...  research was supported in part by the Intramural Research Program of the National Library of Medicine (NLM), and in part by Clinical and Translational Science Award (UL1 RR024989) from the National Center for  ...

Parallelisation strategies for agent based simulation of immune systems

The advantage and disadvantage of each implementation is discussed showing each can be used as the basis for developing complete immune system models on parallel hardware.  ...  Simulating massive multi-agent systems (i.e. simulations containing a large number of agents/entities) requires major computational effort which is only achievable through the use of parallel computing  ...  In this section we describe the FLAME GPU framework used for our implementations; the properties and behaviour of our simplified pairwise model; and provide implementation details of the three alternate  ...

Semantic networks

Fritz Lehmann
1992 Computers and Mathematics with Applications  
Almost all systems have structured concept-hierarchies or taxonomies used for this kind of derivation (described in Section 6), and these hierarchies themselves are also 'semantic networks.'  ...  A knowledgeable person will spot obvious errors in a description whereas a dolt will just accept it.  ...  The OMEGA language for formal descriptions [84] induces a lattice of terms and expressions.  ...
