abstract:
- lang: eng
  text: Knowledge graphs (KGs) differ significantly over multiple different versions
    of the same data source. They also often contain blank nodes that do not have
    a constant identifier over all versions. Linking such blank nodes from different
    versions is a challenging task. Previous works propose different approaches to
    create signatures for all blank nodes based on named nodes in their neighborhood
    to match blank nodes with similar signatures. However, these works struggle to
    find a good mapping when the difference between the KGs’ versions grows too large.
    In this work, we propose Blink, an embedding-based approach for blank node linking.
    Blink merges two KGs’ versions and embeds the merged graph into a latent vector
    space based on translational embeddings and subsequently matches the closest pairs
    of blank nodes from different graphs. We evaluate our approach using real-world
    datasets against state-of-the-art approaches by computing the blank node matching
    for isomorphic graphs and graphs that contain triple changes (i.e., added or removed
    triples). The results indicate that Blink achieves perfect accuracy for isomorphic
    graphs. For graph versions that contain changes, such as having up to 20% of triples
    removed in one version, Blink still produces a mapping with an Optimal Mapping
    Deviation Ratio of under 1%. These results show that Blink leads to a better linking
    of KGs over different versions and similar graphs adhering to the linked data
    guidelines.

  text: Linked knowledge graphs build the backbone of many data-driven applications
    such as search engines, conversational agents and e-commerce solutions. Declarative
    link discovery frameworks use complex link specifications to express the conditions
    under which a link between two resources can be deemed to exist. However, understanding
    such complex link specifications is a challenging task for non-expert users of
    link discovery frameworks. In this paper, we address this drawback by devising
    NMV-LS, a language model-based verbalization approach for translating complex
    link specifications into natural language. NMV-LS relies on the results of rule-based
    link specification verbalization to apply continuous training on T5, a large language
    model based on the Transformerarchitecture. We evaluated NMV-LS on English and
    German datasets using well-known machine translation metrics such as BLUE, METEOR,
    ChrF++ and TER. Our results suggest that our approach achieves a verbalization
    performance close to that of humans and outperforms state of the art approaches.
    Our source code and datasets are publicly available at https://github.com/dice-group/NMV-LS.

  text: "Purpose: Data integration and applications across knowledge graphs (KGs)
    rely heavily on the discovery of links between resources within these KGs. Geospatial
    link discovery algorithms have to deal with millions of point sets containing
    billions of points. \r\nMethodology: To speed up the discovery of geospatial links,
    we propose COBALT. COBALT combines the content measures with R-tree indexing.
    The content measures are based on the area, diagonal and distance of the minimum
    bounding boxes of the polygons which speeds up the process but is not perfectly
    accurate. We thus propose two polygon splitting approaches for improving the accuracy
    of COBALT. \r\nFindings: Our experiments on real-world datasets show that COBALT
    is able to speed up the topological relation discovery over geospatial KGs by
    up to 1.47 × 104 times over state-of-the-art linking algorithms while maintaining
    an F-Measure between 0.7 and 0.9 depending on the relation. Furthermore, we were
    able to achieve an F-Measure of up to 0.99 by applying our polygon splitting approaches
    before applying the content measures. \r\nValue: The process of discovering links
    between geospatial resources can be significantly faster by sacrificing the optimality
    of the results. This is especially important for real time data-driven applications
    such as emergency response, location-based services and traffic management. In
    future work, additional measures, like the location of polygons or the name of
    the entity represented by the polygon, could be integrated to further improve
    the accuracy of the results."

  text: "Purpose: This study addresses the limitations of current short abstracts
    of DBpedia entities, which often lack a comprehensive overview due to their creating
    method (i.e., selecting the first two-three sentences from the full DBpedia abstracts).\r\nMethodology:
    We leverage pre-trained language models to generate abstractive summaries of DBpedia
    abstracts in six languages (English, French, German, Italian, Spanish, and Dutch).
    We performed several experiments to assess the quality of generated summaries
    by language models. In particular, we evaluated the generated summaries using
    human judgments and automated metrics (Self-ROUGE and BERTScore). Additionally,
    we studied the correlation between human judgments and automated metrics in evaluating
    the generated summaries under different aspects: informativeness, coherence, conciseness,
    and fluency.\r\nFindings: Pre-trained language models generate summaries more
    concise and informative than existing short abstracts. Specifically, BART-based
    models effectively overcome the limitations of DBpedia short abstracts, especially
    for longer ones.\r\nMoreover, we show that BERTScore and ROUGE-1 are reliable
    metrics for assessing the informativeness and coherence of the generated summaries
    with respect to the full DBpedia abstracts. We also find a negative correlation
    between conciseness and human ratings. Furthermore, fluency evaluation remains
    challenging without human judgment.\r\nValue: This study has significant implications
    for various applications in machine learning and natural language processing that
    rely on DBpedia resources. By providing succinct and comprehensive summaries,
    our approach enhances the quality of DBpedia abstracts and contributes to the
    semantic web community"

  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.

  text: The creation of an RDF knowledge graph for a particular application commonly
    involves a pipeline of tools that transform a set ofinput data sources into an
    RDF knowledge graph in a process called dataset augmentation. The components of
    such augmentation pipelines often require extensive configuration to lead to satisfactory
    results. Thus, non-experts are often unable to use them. Wepresent an efficient
    supervised algorithm based on genetic programming for learning knowledge graph
    augmentation pipelines of arbitrary length. Our approach uses multi-expression
    learning to learn augmentation pipelines able to achieve a high F-measure on the
    training data. Our evaluation suggests that our approach can efficiently learn
    a larger class of RDF dataset augmentation tasks than the state of the art while
    using only a single training example. Even on the most complex augmentation problem
    we posed, our approach consistently achieves an average F1-measure of 99% in under
    500 iterations with an average runtime of 16 seconds

  text: 'The Linked Data paradigm builds upon the backbone of distributed knowledge
    bases connected by typed links. The mere volume of current knowledge bases as
    well as their sheer number pose two major challenges when aiming to support the
    computation of links across and within them. The first is that tools for link
    discovery have to be time-efficient when they compute links. Secondly, these tools
    have to produce links of high quality to serve the applications built upon Linked
    Data well. Solutions to the second problem build upon efficient computational
    approaches developed to solve the first and combine these with dedicated machine
    learning techniques. The current version of the LIMES framework is the product
    of seven years of research on these two challenges. A series of machine learning
    techniques and efficient computation approaches were developed and integrated
    into this framework to address the link discovery problem. The framework combines
    these diverse algorithms within a generic and extensible architecture. In this
    article, we give an overview of version 1.7.4 of the open-source release of the
    framework. In particular, we focus on an overview of the architecture of the framework,
    an intuition of its inner workings and a brief overview of the approaches it contains.
    Some descriptions of the applications within which the framework was used complete
    the paper. Our framework is open-source and available under a GNU license at https:
    //github.com/dice-group/LIMES together with a user manual and a developer manual.'
