Keynote Speaker Ⅰ
Professor Axel-Cyrille Ngonga Ngomo
Paderborn University, Germany
Biography: Axel holds a Ph.D and habilitation in Computer Science from Leipzig University, Germany. He is currently a Full Professor for Data Science at Paderborn University, where he leads the DICE group. The group focuses on both foundational and applied research all along the lifecycle of knowledge graphs. Hence, it has developed a plethora of algorithms and platforms for knowledge extraction, integration, fusion, and application in intelligent systems. DICE’s research has attracted several international research prizes including best paper awards at top conferences such as ISWC and ESWC. Moreover, Axel is the grateful recipient of several prestigious fellowships for his research, including Northrhine Westphalia’s 2023 Lamarr Fellowship. In his talk, Axel will present some of his recent work on machine learning on knowledge graph with a focus on scalability and explainability.
Speech Title: Scaling up hybrid learning on knowledge graphs
Abstract: Knowledge graphs are an increasingly popular family of data structures for knowledge representation, of which some are endowed with explicit semantics. While learning on graphs is becoming increasingly more popular and scalable, learning on (semantically rich) knowledge graphs is significantly more difficult to achieve. In this talk, we will present recent results on achieving time-efficient and accurate learning on knowledge graphs. We will begin by giving a brief introduction to the class expression learning problem, a supervised learning task on knowledge graphs. We will build upon refinement operators and the corresponding learning principles to derive novel, increasingly more scalable approaches to learning on knowledge graphs while respecting their semantics.
