There is a vast and rapidly increasing quantity of scientific, corporate, government, and crowd-sourced data openly published on the Web. Open Data plays a catalyst role in the way structured information is exploited on a large scale. A traditional view of digitally preserving these datasets by “pickling and locking them away” for future use, like groceries, conflicts with their evolution. There are several approaches and frameworks (Linked Data Stack, PoolParty Suite, etc.) that manage a full life-cycle of the Data Web. More specifically, these solutions are expected to tackle major issues such as the synchronisation problem (monitoring changes), the curation problem (repairing data imperfections), the appraisal problem (assessing the quality of a dataset), the citation problem (how to cite a particular version of a dataset), the archiving problem (retrieving a specific version of a dataset), and the sustainability problem (preserving at scale, ensuring long-term access).

This workshop targets one of the emerging and fundamental problems in the Web, specifically the management and preservation of evolving knowledge graphs.

During the past five years, the MEPDaW workshop series has been gathering researchers from the community around these challenges. So far the series successfully published more than 25 research efforts allowing more than 50 individual authors to present and share their ideas.

This workshop aims at addressing challenges and issues on managing Knowledge Graph evolution and preservation by providing a forum for researchers and practitioners to discuss, exchange and disseminate their ideas and work, to network and cross-fertilise new ideas.

Topics of interest include, but are not limited to themes related to the evolution and preservation of Knowledge Graphs:

  • Management and Governance of Evolution in Knowledge Graphs
    • Representation, maintenance of versions & changes (change representation and detection)
    • Efficient indexing and update of Knowledge Graphs
    • Synchronization of distributed versions
    • Federated Knowledge Graph governance
  • Reasoning and Prediction over Evolving Knowledge Graphs
    • Techniques for extracting and predicting evolving patterns
    • Maintenance of explicit and implicit knowledge
    • Trend analysis of evolving knowledge graphs
    • Concept drift detection and prediction over knowledge graphs
  • Visualization and Exploration of Evolving Knowledge Graphs
    • Visual summarization of evolving knowledge
    • User interfaces for exploring evolving knowledge graphs
    • Visualisation of quality in knowledge graphs
  • Preservation of Evolving Knowledge Graphs
    • Preservation of context, provenance and background knowledge
    • Efficient and effective solutions for preserving evolving knowledge graphs
    • Models for representing provenance and evolution
  • Quality of Evolving Knowledge Graphs
    • Change-detection based quality assessment and validation
    • Quality trends and prediction in evolving knowledge graphs
    • Hybrid approaches for knowledge graph curation
  • Evaluation of Knowledge Graph Evolution
    • Benchmarks for managing, predicting, and curating evolution
    • Real-world applications of evolving knowledge graphs
    • Automatic and human-based techniques for evaluating evolving knowledge graph

We envision four types of submissions covering the entire workshop topics spectrum:

  1. Research Papers (max 10 pages), presenting novel scientific research addressing topics of the workshop.
  2. Position & Demo papers (max 5 pages), encouraging papers describing significant work in progress, late breaking results or ideas of the domain, as well as functional systems relevant to the community.
  3. Industry & Use Case Presentations (max 5 pages), in which industry experts can present and discuss practical solutions, use case prototypes, best practices, etc. at any stage of implementation.
  4. Expression of Interest (max 2 pages), presenting a research topic, a work in progress, practical applications or needs, etc.

The proceedings of the workshops will be published in the CEUR-WS. Papers must be submitted in PDF according to the LLNCS format or in HTML. The PDF files must have all non-standard fonts embedded. Workshop submissions must be self-contained and in English.

All papers should be submitted to https://easychair.org/conferences/?conf=mepdaw2020.
