Knowledge Graphs and Semantic Computing Speaker Series: Jay Pujara

Jay Pujara

Jay Pujara, Research Assistant Professor in Computer Science at the University of Southern California, will present "Knowledge Graphs for a Deeper Understanding of Science."

Jay Pujara is a research assistant professor of Computer Science at the University of Southern California as well as research team lead and director of the Center on Knowledge Graphs at USC's Information Sciences Institute. His research focuses on artificial intelligence, specifically knowledge graphs and statistical relational learning. Jay is the author of over 50 peer-reviewed publications, has received four best paper awards, and has been featured in AI Magazine.

Scientific research is the foundation of human progress. One approach to better understand the processes underlying scientific research is through analyzing scientific publications, their authors, and the relationships between them. I will describe PubGraph, a publication KG with over 15B edges built on the Wikidata ontology. Next, I will present results of several applications of PubGraph, including assessing the reproducibility of scientific publications, patterns of bias in scientific communities, transductive and inductive link prediction between scientific works, and modeling research dynamism.
