Lukas Laskowski.
I am a PhD student @ HPI.
PhD Student at the Hasso Plattner Institute, advised by Prof. Felix Naumann. My research focuses on data cleaning, AI, and computer vision applications for wildlife conservation.
Hi, my name is
Experience
My research, sponsored by SAP SE, focuses on developing ontology learning systems that transform structured data into meaningful knowledge representations. I’m particularly interested in the intersection of data management, AI, and semantic technologies.
I’m currently conducting a research visit at UC Irvine, working with Prof. Padhraic Smyth. Together, we’re developing a human-in-the-loop ontology learning system that leverages a sequence-to-sequence (seq2seq) architecture. The goal is to integrate expert feedback into the learning loop for more accurate and interpretable knowledge extraction.
I conduct research on wildlife re-identification AI technologies for a species conservation startup based in East-Central Africa. The work focuses on applying computer vision to support the monitoring and protection of endangered animals in the wild.
- Published a paper on the use of AI for wildlife conservation (link).
I designed and developed the central automated edge provisioning solution for a global Industrial IoT platform (“Connected Factory”), actively contributing to the core implementation.
- Realization of the new global platform for Industrial IoT to connect industrial plants to the cloud (“Connected Factory”)
- Responsible for the system architecture and development of the central automated edge provisioning solution
- Technical management of external project staff in Europe and India
- Planning the introduction of the cloud platform in over 80 factories
I administered services on the SAP Cloud Platform and developed automated deployment pipelines to streamline delivery processes. Additionally, I worked on the development and optimization of ABAP components to enhance system performance and reliability.

Frost: A Platform for Benchmarking and Exploring Data Matching Results
We introduce Frost, the first platform to systematically evaluate and explore data deduplication solutions by combining quality, cost, and effort metrics with interactive result exploration—addressing the limitations of existing benchmarks that focus solely on matching accuracy.

Prisma: A Privacy-Preserving Schema Matcher using Functional Dependencies
Prisma introduces a novel approach to schema matching that leverages functional dependencies and graph embeddings to identify column correspondences without relying on name or data similarity. Prisma outperforms existing methods, particularly in multi-table databases with significantly different or encrypted encodings.

GorillaVision – Open-Set Re-Identification of Wild Gorillas
This work introduces an open-set re-identification system for gorillas in the wild, combining YOLOv7 face detection with a Vision Transformer-based embedding model trained using Triplet Loss. By classifying embeddings with a k-nearest neighbors algorithm, the system enables reliable identification of unseen individuals, achieving 60–90% accuracy depending on dataset quality and population size.
Highlights
Research Visit at UC Irvine Feb - May 2025
I'm excited to be conducting a research visit at UC Irvine, working with Prof. Padhraic Smyth on human-in-the-loop ontology learning. Our work combines methods from databases, the Semantic Web, and AI to create more interactive and adaptive knowledge systems.
