Transactions on Graph Data and Knowledge (TGDK) is an Open Access journal that publishes research contributions relating to the use of graphs for data and knowledge management. Such contributions may be experimental or theoretical in nature, where submissions that combine both aspects are particularly welcome. The journal thus welcomes submissions from research communities – such as Graph Analytics and Algorithms, Graph Databases, Graph Representation Learning, Knowledge Graphs, Semantic Web – that provide novel insights into the use of graphs for generating, representing and managing data and knowledge. Likewise contributions relating to the use of graphs in the context of Big Data, Data Integration, Data Science, Information Extraction, Information Retrieval, Knowledge Representation, Machine Learning, Natural Language Processing, etc., are welcome.
Submissions will be judged based on novelty, technical correctness, technical depth, readability, reproducibility, relevance to the scope, and potential for impact and follow-up research. For the submission process, see the author instructions.
