Data

I work mostly with linked data and knowledge graphs. I perform analysis, study the features and develop refinement algorithms to improve the quality of data. I have also developed tools for fast manual annotation.
In addition, I have worked with proofs in higher order logic as well as data in bioinformatics.

  • c

    Data Analysis

    I perform logic-based and graph-theoretical analysis of large knowledge graphs.

  • t

    Refinement

    I develop hybrid refinement algorithms and improve the quality of large knowledge graphs.

  • n

    Validation and Checking

    I worked with proofs of higher order logic (transformation, validation, and proof checking).

  • p

    Feature Analysis

    I use various tools for the extraction and analysis of features in knowledge graphs.

  • l

    Annotation

    I developed tools for the annotation of gold standards.

  • h

    Publishing

    I have published many datasets on Zenodo, TriplyDB, etc.

Below are some datasets that come out of my recent research:

  • A mapping between the DMP questions and FIP questions

    Here you can find a mapping from the questions of Vrije Universiteit Amsterdam's data management plan to the questions in the FAIR Implemenation Profile.
    You can also reuse the knowledge model to create an interface on FAIR Wizard

    Large multilingual integrated knowledge datasets of the resilience of Ukraine

    The enriched datasets are available on TriplyDB.
    The large multilingual integrated dataset is available upon request only.
    See details on the website.

    FAIR Implementation Profile for Social Science

    The repository consists of six FIPs and some comparison and a convergence analysis as well as related files.
