About TGDK

Transactions on Graph Data and Knowledge (TGDK) is an Open Access journal that publishes research on graph-based abstractions for data and knowledge, and the techniques that such abstractions enable with respect to integration, querying, reasoning and learning. The scope of the journal thus intersects with areas such as Graph Algorithms, Graph Databases, Graph Representation Learning, Knowledge Graphs, Knowledge Representation, Linked Data and the Semantic Web.

Also in scope is research investigating graph-based abstractions of data and knowledge in the context of Data Integration, Data Science, Information Extraction, Information Retrieval, Machine Learning, Natural Language Processing, and the Web.

The journal is Diamond Open Access, with no fees for readers or authors. Papers are published by Dagstuhl Publishing under CC BY 4.0, and authors retain copyright.
