Master Project

Data integration (or data interoperability) is still a major problem in industry that creates a lot of overhead in digitalization projects. Relevant examples of data integration problems include entity matching, (i.e., linking records to entities), and schema alignment (i.e., aligning types and attributes from multiple sources).

A common approach to solve data integration is to implement tailored made solutions for particular applications, projects and organisations. These solutions are expensive to develop and maintain, and they are not suitable to be generalized to support a larger range of problems and projects.

Large companies such as Amazon, Google, Apple and IBM are applying Large Language Models such as ChatGPT to enable a higher degree of automation for data integration problems. However, these techniques are still not known or adopted by many companies and public institutions.

Research Topic focus

The goal of this thesis is to explore the applicability of ChatGPT to solve data integration problems in real national or European projects aiming to create digital twins for different domains such as Energy, Manufacturing, Maritime and Biology.

Expected Results and Learning Outcome

After the thesis is successfully submitted and defended, the student should have a better understanding and practical experience working with ChatGPT and other language models such as LLaMa 2 (by Meta). This includes the ability to describe complex tasks using prompt engineering techniques and adapt ChatGPT for solving particular problems using fine-tuning.


Candidates should have a good understanding on deep learning techniques, data engineering, and semantic technologies. Moreover, it will be recommended programming experience in Python with libraries for data processing (e.g., Pandas, SQLAlchemy, etc.), data analytics (NumPy, Scikit-learn, TensorFlow, PyTorch, etc.) and data visualisation (e.g., Matplotlib, Seaborne, etc.).
