  text: Graffiti is an urban phenomenon that is increasingly attracting the interest
    of the sciences. To the best of our knowledge, no suitable data corpora are available
    for systematic research until now. The Information System Graffiti in Germany
    project (Ingrid) closes this gap by dealing with graffiti image collections that
    have been made available to the project for public use. Within Ingrid, the graffiti
    images are collected, digitized and annotated. With this work, we aim to support
    the rapid access to a comprehensive data source on Ingrid targeted especially
    by researchers. In particular, we present IngridKG, an RDF knowledge graph of
    annotated graffiti, abides by the Linked Data and FAIR principles. We weekly update
    IngridKG by augmenting the new annotated graffiti to our knowledge graph. Our
    generation pipeline applies RDF data conversion, link discovery and data fusion
    approaches to the original data. The current version of IngridKG contains 460,640,154
    triples and is linked to 3 other knowledge graphs by over 200,000 links. In our
    use case studies, we demonstrate the usefulness of our knowledge graph for different
    applications.
