Ontology summarization based on rdf sentence graph
2007
Proceedings of the 16th international conference on World Wide Web - WWW '07
We propose a notion of RDF sentence as the basic unit of summarization. An RDF Sentence Graph is proposed to characterize the links between RDF sentences derived from a given ontology. ...
The salience of each RDF sentence is assessed in terms of its "centrality" in the graph. ...
CONCLUSION AND FUTURE WORK In this paper, we proposed a novel approach to automatic ontology summarization based on RDF Sentence Graph. ...

Graph-based Ontology Summarization: A Survey
[article]
2018
arXiv
pre-print
In this survey paper, we review existing ontology summarization techniques and focus mainly on graph-based methods, which represent an ontology as a graph and apply centrality-based and other measures ...
Consequently, ontology summarization, as a way to distill key information from an ontology and generate an abridged version to facilitate a better understanding, is getting growing attention. ...
Betweenness has also been used on RDF sentence graph [23] . ...

A Comprehensive Survey of Ontology Summarization: Measures and Methods
[article]
2018
arXiv
pre-print
In this paper, we mainly focus on the common metrics which are using for ontology summarization and meet the state-of-the-art in ontology summarization. ...
There are various approaches available for ontology summarization which are focusing on different measures in order to produce a proper summary for a given ontology. ...
In fact, from RDF sentence Builder and Graph Builder components the ontology is mapped to a set of RDF sentences and an RDF Sentence Graph is build based on set of RDF sentences and user's preference. ...

A Framework for Semantic Text Clustering
2020
International Journal of Advanced Computer Science and Applications
The framework allows documents RDF representation, clustering, topic modeling, clusters summarizing, information retrieval based on RDF querying and Reasoning tools. ...
On the other hand, this study opts to implement other techniques within the clustering process such as ontology representation to manipulate and extract meaningful information using RDF, RDF Schemas (RDFS ...
There are multiple RDF summarization approaches, some include ontologies to handle the summarization of an RDF graph, and others can ignore their use and only work on the bare RDF graph. ...

In this paper, we illustrate a good snippet in a keyword-based ontology search engine should be with term-association view and compact, and propose an approach to generate it. ...
To obtain term-association view snippets, a model of term association graph for ontology is proposed, and a concept of maximal r-radius subgraph is introduced to decompose the term association graph into ...
