- sl:arxiv_summary : RDF2vec is an embedding technique for representing knowledge graph entities
in a continuous vector space. In this paper, we investigate the effect of
materializing implicit A-box axioms induced by subproperties, as well as
symmetric and transitive properties. While it might be a reasonable assumption
that such a materialization before computing embeddings might lead to better
embeddings, we conduct a set of experiments on DBpedia which demonstrate that
the materialization actually has a negative effect on the performance of
RDF2vec. In our analysis, we argue that despite the huge body of work devoted
on completing missing information in knowledge graphs, such missing implicit
information is actually a signal, not a defect, and we show examples
illustrating that assumption.@en
