Project Overview #
The “GeoQA” project has three objectives: (i)to extend existing knowledge graphs with geographic knowledge found in important geospatial datasets available on the Web, (ii) to develop techniques and systems for answering complex non-factoid questions over such geospatial knowledge graphs effectively and efficiently, and (iii) to develop a gold standard set of questions and their corresponding GeoSPARQL queries for evaluating geospatial question engines.
My contribution #
- Developed an engine for geospatial question-answering over knowledge graphs that incorporates Large Language Models for query generation (Work Package 2).
- Redesigned the question-answering pipeline to speed-up query generation by an order of magnitude (Work Package 2).
- Lead the development of GeoQuestions1089, the largest crowdsourced geospatial-question answering dataset (Work Package 3).
