Problem
The problem the paper is addressing is the importance of Ontology Summarization to understand and select ontologies.
The problem interesting because there is no published work on ontology summarization

SolutionRDF Sentence Builder
OntologyLengthPreference
Graph BuilderBuilds RDF Sentence GraphsDescribes links between RDF Sentences
Salience AssessorRanks RDF sentences based the link analysis of the graph“Centrality”
Re-rankerProduces final summaryRanking algorithm reduces redundancy and enhances coherence

Criticism
Interesting because there currently is no published work on ontology summarization
Since there was no published work on ontology summarization, they had to evaluate their ontology summarization based on text summarization and not other ontology summarizations
