Phd Position in Parsing and Formal Representation of Geographic Questions

**Your job**:
Answering geographic questions like “What is the potential to reduce urban heat in Amsterdam by installing green roofs on existing buildings?” is important in fields such as urban planning, sustainability, and public health. Most current Geographic Question Answering (GeoQA) tools only return short factual answers, but many real-world questions—like this example—require deeper spatial analysis.

This PhD position focuses on developing a method for parsing and formalising geo-analytical questions. You will explore hybrid AI supported approaches to help users formulate and translate natural language questions into structured representations that can be linked to geospatial data sources and workflows.

You will contribute to the design of the linguistic and conceptual interface between natural language questions and formal workflow models over a geodata repository. In this project, you will:

- build and annotate a corpus of geo-analytical questions and their associated purposes, data needs, and analytical steps in geo-analytical standard scenarios;
- develop a model of geo-analytical purposes (transformation requests) and a corresponding question grammar;
- perform a user study on geo-analytical question formulation to express such purposes;
- contribute to the formalisation of spatial question types using a purpose-driven taxonomy;
- develop a hybrid question parsing pipeline using NLP and formal semantic representations; investigate Large Language Models (LLMs) as well as symbolic AI for question parsing;
- evaluate models based on a gold standard of geo-analytic purposes and questions;

It is part of the ERC-funded project GeoTrAnsQData, which develops the foundations of a transformative GeoQA methodology through an integrated research program across geoinformatics, AI, and geography. The project is based at the Department of Human Geography and Spatial Planning, Utrecht University, and contributes to cutting-edge research on spatial reasoning, semantic technologies, and interdisciplinary AI for geosciences and geography.

**Your qualities**:
This position is ideal for someone interested in natural language processing, geographic information and conceptual modelling. You have the following qualifications:

- a completed or near-completed MSc degree in Artificial Intelligence, Computational Linguistics, GeoInformatics, Geography, Geoscience, or a related field;
- experience with natural language processing (NLP), language modelling, grammatical models, and question-answering (QA)
- a strong interest in maps and geographic information as well as spatial questions;
- an interest in conceptual modelling, knowledge representation and knowledge graphs;
- programming skills in Python and knowledge of relevant NLP libraries (e.g. spaCy, Hugging Face Transformers);
- good English communication skills and an interest in interdisciplinary collaboration.

**Our offer**:

- A position for one year, with an extension to a total of four years upon a successful assessment in the first year, and with the specific intent that it results in a doctorate within this period;
- a working week of 38 hours and a gross monthly salary between €3,059 and €3,881 (salary scale P under the Collective Labour Agreement for Dutch Universities (CAO NU));
- 8% holiday pay and 8.3% year-end bonus;
- a pension scheme, partially paid parental leave and flexible terms of employment based on the CAO NU.

In addition to the terms of employment laid down in the CAO NU, Utrecht University has a number of schemes and facilities of its own for employees. This includes schemes facilitating professional development, leave schemes and schemes for sports and cultural activities. We also offer access to additional employee benefits through our Terms of Employment Options Model. In this way, we encourage our employees to continue to invest in their growth.
