RV-Xplorer: A Way to Navigate Lattice-Based Views over RDF Graphs

Mehwish Alam, Matthieu Osmuk, Amedeo Napoli
2015 International Conference on Concept Lattices and their Applications  
With the help of this View By clause a concept lattice is created as an answer to the SPARQL query which can then be visualized and navigated using RV-Xplorer (Rdf View eXplorer).  ...  Accordingly, this paper discusses the support provided to the expert for answering certain questions through the navigation strategies provided by RV-Xplorer.  ...  Lattice-Based Views over RDF Graphs http://conexp.sourceforge.net/ RV-Xplorer: A Way to Navigate Lattice-Based Views over RDF Graphs  ...

Steps Towards Interactive Formal Concept Analysis with LatViz

Mehwish Alam, Thi Nhu Nguyen Le, Amedeo Napoli
2016 European Conference on Artificial Intelligence  
To achieve this goal, we introduce a new tool called LatViz, which implements several algorithms for constructing concept lattices and allows further navigation over lattice structure.  ...  This way the user can effectively perform an interactive exploration over a concept lattice which is a basis for a strong user interaction with WOD for data analysis.  ...  It clusters RDF triples based on RDF Schema and then allows interactive exploration with the help of RV-Xplorer (Rdf View eXplorer) [3] .  ...

Exploratory knowledge discovery over Web of Data

Mehwish Alam, Aleksey Buzmakov, Amedeo Napoli
2018 Discrete Applied Mathematics  
This research work proposes a new approach based on Formal Concept Analysis and Pattern Structures for building a pattern concept lattice from a set of RDF triples.  ...  The specific pattern structure introduced for RDF data allows to make a bridge with other studies on the use of structured attribute sets when building concept lattices.  ...  This RDF-Index provides a centralized "view" over distributed resources and serves as a navigation and exploration space for the analyst.  ...

Interactive exploration over RDF data using formal concept analysis

Mehwish Alam, Amedeo Napoli
2015 2015 IEEE International Conference on Data Science and Advanced Analytics (DSAA)  
This paper proposes a new approach based on interactive data exploration paradigm using Pattern Structures, an extension of Formal Concept Analysis, to provide exploration and navigation over Linked Data  ...  It takes RDF triples and RDF Schema based on user requirements and provides one navigation space resulting from several RDF resources.  ...  A pattern concept lattice (navigation space) was built using the paper titles, their keywords and authors. The results were visualized using the tool RV-Xplorer (Rdf View eXplorer) [14] .  ...
