Ontology Matching Through Absolute Orientation of Embedding Spaces
Jan Portisch, Guilherme Costa, Karolin Stefani +3
Ontology matching is a core task when creating interoperable and linked open datasets. In this paper, we explore a novel structure-based mapping approach which is based on knowledg…
Background Knowledge in Schema Matching: Strategy vs. Data
Jan Portisch, Michael Hladik, Heiko Paulheim
The use of external background knowledge can be beneficial for the task of matching schemas or ontologies automatically. In this paper, we exploit six general-purpose knowledge gra…
FinMatcher at FinSim-2: Hypernym Detection in the Financial Services Domain using Knowledge Graphs
Jan Portisch, Michael Hladik, Heiko Paulheim
This paper presents the FinMatcher system and its results for the FinSim 2021 shared task which is co-located with the Workshop on Financial Technology on the Web (FinWeb) in conju…
RDF2Vec Light -- A Lightweight Approach for Knowledge Graph Embeddings
Jan Portisch, Michael Hladik, Heiko Paulheim
Knowledge graph embedding approaches represent nodes and edges of graphs as mathematical vectors. Current approaches focus on embedding complete knowledge graphs, i.e. all nodes an…
KGvec2go -- Knowledge Graph Embeddings as a Service
Jan Portisch, Michael Hladik, Heiko Paulheim
In this paper, we present KGvec2go, a Web API for accessing and consuming graph embeddings in a light-weight fashion in downstream applications. Currently, we serve pre-trained emb…
