Identifying Mappings among Knowledge Graphs by Formal Concept Analysis

Guowei Chen, Songmao Zhang
2019 International Semantic Web Conference  
Formal Concept Analysis (FCA) is a well-developed mathematical model for clustering individuals and structuring concepts.  ...  Based on the lexical instance mappings, we further construct a property-based formal context to identify commonalities among properties in a structural way, which indicates a promising direction for taking  ...  As shown by the gray area, a property mapping ⟨MA:wsteleplayby, MB:teleplay⟩ is identified by structural knowledge rather than by names.  ...

Concept Landscapes: Aggregating Concept Maps for Analysis

Andreas Muehling
2017 Zenodo  
This article presents concept landscapes - a novel way of investigating the state and development of knowledge structures in groups of persons using concept maps.  ...  Electronic collection of concept maps makes it feasible to aggregate the data of a large group of persons, which in turn favors a data mining approach to analysis.  ...  For example, when applying cluster analysis to focus on inherent differences in knowledge structures, it makes sense to afterward look for common elements among the identified clusters to better characterize  ...

Ontology research and development. Part 2: A review of ontology mapping and evolving

Y. Ding, S. Foo
2002 Journal of Information Science  
Ontology mapping is concerned with reusing existing ontologies, expanding and combinin g them by some means and enable a larger pool of information and knowledge in different domains to be integrated to  ...  Ontology is a formal explicit specification of a shared conceptualization. Ontology itself is not a static model so that it must have the potential to capture changes of meanings and relations.  ...  Formal Concept Analysis (Ganter & Wille, 1999) offers formalization by mathematizing the concept as a unit of thought constituted of two parts: its extension and its intension.  ...

Relationships among Knowledge Structures: Vocabulary Integration within a Subject Domain [chapter]

Olivier Bodenreider, Carol A. Bean
2001 Information Science and Knowledge Management  
This paper focuses on three types of relationships among terms: synonymy, hierarchical relationships, and explicit mapping relationships.  ...  The structure of terminology systems can be seen as one way to organize knowledge.  ...  In the UMLS, concepts are defined by extension: that is, by a list of terms that are equivalent in meaning. The concept is a sort of virtual entity, identified by a unique identifier (CUI).  ...
