About Me

Hi! I’m Jessica Cheng, officially Yi-Yun Cheng. I am a PhD candidate at the School of Information Sciences, University of Illinois at Urbana-Champaign. I am working with Bertram Ludäscher at the Center for Informatics Research in Science and Scholarship (CIRSS).

My doctoral research focuses on solving metadata interoperability problems in knowledge organization systems (taxonomies, classification systems, metadata standards, and ontologies) by employing a logic-based approach to resolve conflicting vocabularies. Specifically, the logic-based approach draws on theories from first order predicate logic, set theory, and qualitative reasoning. My specific domain of interest for this work is biodiversity informatics, and how, by solving interoperability issues in this domain, can advance our understandings towards biodiversity data integration. My doctoral dissertation is titled: Agreeing to Disagree: Applying a Logic-based Approach to Reconciling and Merging Multiple Taxonomies. 

I am a recipient of the 2021 Eugene Garfield Doctoral Dissertation Fellowship from the Beta Phi Mu Honor Society. I was also a LEADS-4-NDP fellow from 2019-2020, working with Steven Dilliplane from the Academy of Natural Sciences and Dr. Jane Greenberg from Drexel University, on the project “From Natural History Literature to Linked Data Biodiversity Knowledge Graph”.  I publish in Knowledge Organization Journal, ASIS&T, iConference, NASKO, etc.  I am also currently working on book chapters about Provenance metadata with Drs. Rhiannon Bettiva (Simmons University) and Michael Gryk (UConn).
