Graph Databases for Fast Queries in UD Treebanks

Paper i proceeding, 2025

We investigate if labeled property graphs, and graph databases, can be an useful and efficient way of encoding UD treebanks, to facilitate searching for complex syntactic phenomena. We give two alternative encodings of UD treebanks into the off-the-shelf graph database Neo4j, and show how to translate syntactic queries into the graph query language Cypher. Our evaluation shows that graph databases can improve query times by several orders of magnitude, compared to existing approaches.
