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. For my PhD, I have also developed tools for fast manual annotation. Throught supervising students, we have generated and studied A.I. generated art.
In addition, I have worked with proofs (in higher order logic).

  • 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.

    Publishing

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

Here are some datasets from my most recent research:



  • FAIR Assessment Results of Datasets by the GLOBALISE Community And Their Aggregating

    Description This dataset corresponds to our paper with the same title. The dataset consists of FAIR assessment results from F-UJI and FAIR Checker over selected datasets from the GLOBALISE Community on two data repositories: IISG Dataverse and Zenodo.

    Below are some datasets from my past research:



    • Visio Divina Dataset:

      A large dataset of 7K images generated using biblical text.
      See details on the webpage of DANS SSH data station (link).

      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
