Knowledge base population and visualization using an ontology based on semantic roles
2013
Proceedings of the 2013 workshop on Automated knowledge base construction - AKBC '13
Preserved Fulltext
To this end, we tightly couple our knowledge base and ontology to an information visualization system that can be used to explore and navigate events extracted from a large natural language text collection ...
We exploit semantic role labels in order to create a novel predicate-centric ontology for entities in our knowledge base. This allows users to find uncommon facts easily. ...
Semantic Roles and Predicate-centered Ontology To extract predicate-argument structures, we use an SRL approach based on large-scale statistical machine learning [6, 8] based on a semantic role data ...

One such motivation is that a model often needs to play more than one role in an application: A particular concept should be viewed as a class in one role but as an instance in another role. ...

The ontologies defined are also used in the visualization of the search results, providing an interactive environment for users to explore, discover, and analyze the information. ...
Ontology-based Semantic Search A search mechanism with semantic features needs to interpret a knowledge model about a domain and an ontology is an approach to represent this knowledge [16, 9, 3 and 17 ...

However, recent advances in semantic web technologies have presented exciting new opportunities for pharmacogenomics knowledge discovery by representing the information with machine understandable semantics ...
With a populated ontology in hand, new approaches to mine the knowledge base found on the semantic web will uncover new patterns in the information, which in turn can be captured as expressive ontologies ...
