GeoChanges QA

<p>This work introduces GeoChangesQA, a novel spatiotemporal QA dataset for historical geospatial knowledge. We first developed the Historical County Boundaries Ontology (HCB-O) to create this dataset. Then, we leveraged geospatial historical data spanning regions in the United States from 1630 to 2000 to populate the novel Historical County<br>Boundaries Knowledge Graph (HCB-KG). Subsequently, we developed a semi-automated procedure for generating questions, GeoSPARQL queries, and corresponding answers over HCB-KG by leveraging subgraph and query template extraction techniques. Through this method, we automatically generated 8, 900 question-query-answer triples.</p> <p>The code used to create this dataset is available here: &nbsp;<a href="https://github.com/AI-team-UoA/GeoChanges-Dataset">github repo</a></p> <p>The knowledge graph (rdf dumps) which the queries refer to is available here: DOI <a href="../doi/10.5281/zenodo.11508198">10.5281/zenodo.11508198</a>&nbsp; //&nbsp; <a title="Knowledge Graph" href="https://drive.google.com/drive/u/1/folders/1HFWT9dvkB8LRkhOxoLfFum8RRrIzkHQg">Knowledge Graph</a></p>
