Jessica Yi-Yun Cheng in interested in investigating how interoperability issues in taxonomies and metadata, may have implications towards data curation.  Her work leverages conceptual modeling, qualitative reasoning, and logic-based methods for merging and aligning geographic and biodiversity taxonomies.

 Cheng's current research projects focus on the following topics:

  • Comparing different alignment methods used in knowledge organization systems
  • Investigating implicit assumptions in geographic taxonomies 
  • Exploring the use of provenance metadata and conceptual models
  • Examining data curation practices in biodiversity data and natural history museum collections


The goals of these ongoing projects are to improve understanding towards long-term data curation in biodiversity, and to inform better design and modeling of knowledge graphs.
