Sam Grabus

Sam Grabus is a senior ontologist at Johns Hopkins Applied Physics Laboratory. Sam holds a Ph.D in Information Science and M.S. in Library and Information Science from Drexel University’s College of Computing and Informatics, as well as a B.S. in English Language and Literature from Towson University. Sam’s doctoral research centered on knowledge organization systems, automating subject representation, and topical relevance assessment. Sam’s dissertation research addresses how we can harness historical terminologies and ontologies and use topical metadata to provide subject representation and contextualization for knowledge that has changed over time and link deprecated terms to their contemporary counterparts. Her published research primarily focuses on computational approaches to knowledge extraction and representation for resources using large-scale ontologies and controlled vocabularies. She has also explored the use of named entity recognition for refining automatic indexing approaches. Sam has also published metadata and ontology research related to data sharing for sensitive and closed data types.
