FrontierSI Staff Presentation – Project Update on Geospatial Intelligence Research

UNSW Postdoctoral Researcher Dr Rabindra Lamsal, together with Prof. Sisi Zlatanova, recently presented an update on their research project,

Geospatial Intelligence to Support Machine–Human Native Conversation”, at the FrontierSI staff meeting.

The project aims to design a conversational system that enables natural language interaction with complex geospatial datasets. It is structured in two phases:
(i) developing a conversational system for Industry Foundation Classes (IFC) models; and
(ii) extending this capability to support combined 3D city models and IFC models.

The presentation focused on the completion of the first phase.

Working with IFC models typically requires substantial technical expertise, including proficiency in specialised BIM tools, software libraries and programming environments. These barriers often limit meaningful engagement with IFC data to technical specialists. While Large Language Models (LLMs) present new opportunities for natural language interaction, their limited context capacity — combined with the large size and structural complexity of raw IFC files — makes it impractical to directly ingest entire IFC datasets for querying.

To address this challenge, the research team developed a hybrid relational–graph LLM framework for natural language querying of IFC models. Rather than relying on raw file input, the framework transforms IFC data into structured relational and graph database representations that are more efficient for LLM-based traversal and reasoning. This architectural approach enables scalable, accurate querying without exceeding model limitations.

An implementation of the framework was demonstrated during the presentation. Testing across three IFC models of varying sizes achieved accuracy rates between 93.3% and 100%, demonstrating both robustness and adaptability.

The hybrid framework represents the principal contribution of Phase One and the associated manuscript is currently under journal review. In parallel, the team has developed a complementary semantic retrieval helper system for the IFC schema, designed to enhance performance in similar LLM-based querying frameworks. This supporting work has been accepted for publication in the *Annals of the ISPRS Congress 2026*.

The session provided FrontierSI staff with a comprehensive overview of progress to date and set the foundation for Phase Two of the project, which will extend the conversational system to integrated 3D CityGML and IFC environments.

Milad Mousavi Wins Best Presentation Award at ICMLT 2025

 

Milad Mousavi, a RIIS Hub student and researcher from the School of Civil and Environmental Engineering at UNSW Sydney, was honored with the Best Presentation Award at the 10th International Conference on Machine Learning Technologies (ICMLT 2025), held in Helsinki, Finland from May 23–25, 2025. His paper, “Online Deep Transfer Learning and Multi-Sensor Analysis for Enhanced Underground Monitoring,” introduces a novel approach to improving safety and efficiency in underground environments.

Tackling the Challenges of Underground Monitoring

Underground operations, such as coal mining, face significant challenges due to complex spatial layouts, unpredictable geological conditions, and hazardous gas emissions—particularly methane. Traditional monitoring systems often struggle with data scarcity and adaptability, especially during the early stages of operation.
Milad’s research addresses these limitations by integrating multi-sensor analysis with online transfer learning, enabling real-time prediction and monitoring of methane concentrations. His model leverages a Long Short-Term Memory (LSTM) neural network trained on data from a Polish coal mine and fine-tuned using online learning with data from a Chinese coal mine.

Key Innovations and Results

The study demonstrates that combining historical data with real-time updates significantly enhances prediction accuracy. Notably:

– The online transfer learning model achieved an R² score of 0.93, indicating high reliability in methane concentration predictions.
– The model trained with transfer learning showed faster performance improvements compared to models trained from scratch.
– This approach helps mitigate the “cold start” problem in new underground projects, where data is initially limited.
By continuously adapting to new data, the model supports timely interventions, reduces false alarms, and improves operational efficiency—ultimately contributing to safer underground environments.

A Vision for the Future

Milad’s work, as a RIIS Hub student supported by the ARC Research Hub for Resilient and Intelligent Infrastructure Systems (RIIS), sets a new benchmark for intelligent underground monitoring. His presentation at ICMLT 2025 not only showcased technical excellence but also highlighted the practical impact of machine learning in infrastructure resilience and safety.
As underground operations become increasingly digitized, innovations like Milad’s will play a crucial role in shaping the future of smart, adaptive monitoring systems.

Research Poster Title: Seismic Data Denoising with a Single-Shot Deep Learning Approach: Double-DIP
Research Insight:
Denoising is an essential step in seismic data interpretation. We proposed a novel deep learning approach where one neural network predicts the clean signal while another estimates the original noise. This single-shot method requires no additional training data, working directly on a single image. It effectively preserves structural information while achieving superior denoising performance.
Industry partner on this project: Kumul Petroleum

Runner Up Poster: Amir Fila
Research Poster Title: A Graph Theory Approach for Aerial Point Cloud Segmentation and Processing
Research insight:
The majority of research on aerial point cloud data segmentation uses the term ‘complexity’ vaguely by abstractly assigning higher complexity to those point cloud datasets with higher computation requirements. As part of my PhD research, I aim to provide a mathematical approach, leveraging graph theory and Laplacian matrix analysis, to address the complexity elements inherent in aerial LiDAR captures. This approach will serve as a valuable tool for understanding complexity across different sections of a given point cloud dataset, ultimately aiding in noise recognition and boundary detection processes.

RIIS Hub is working to minimise damage to homes when disaster strikes

Australia is a land of ‘droughts and flooding rains’*, and when they occur soils can swell or shrink, which can result in damage to buildings and homes, and pose a risk to human life.

The personal and collective financial cost of addressing flood-related structural damage to homes is not limited to Australia. It is an international challenge.
Damage to infrastructure could be minimised or avoided with a better understanding of soil behaviour under different conditions, and RIIS Hub is contributing to global learning on the topic.
To further explore international learnings on the topic, RIIS Hub team recently welcomed eminent scholar and researcher in soil-related structural impacts Associate Professor Mathilde Morvan from the Pascal Institute & POLYTECH Clermont in France to explore potential solutions.
A/Prof Morvan’s current research seeks to develop a better understanding of soil characterisation. She is also looking to develop new, inexpensive diagnostic methods that can predict swelling soils near detached houses.
A/Prof. Morvan’s work has close alignment to some of the and predictive techniques being developed in RIIS Hub’s Theme 3 Research program, where researchers are exploring the effect of temperature on the movement of soils using a thermo-plasticity model as part of flaw detection and failure avoidance research.
During her Seminar to the RIIS Hub team, A/Prof Morvan shared

• The cost of damage due to soil shrinkage and swelling on detached houses is the highest among natural disasters in France after floods.
• While methods for characterising these soils exist, they are generally not affordable for most households, and as a result, this foundational soil understanding is often neglected at building and planning development stages.
• One objective of A/Prof. Morvan’s work is to provide a methodology for characterising these soils, and to find simple. Another is to find affordable methods to help spur more due diligence soil investigations to inform structural planning and help prevent damage to homes during disasters.
• A current project proposes to develop a method for monitoring individual houses in high-risk areas, with the aim of providing reliable data.

Following the presentation A/Prof. Morvan spent 1:1 time collaborating with members of the RIIS Hub team, exploring future research and data sharing.
RIIS Hub Director Prof. Nasser Khalili shared:
“We want to make flood affected dwellings are as ‘safe as houses’, and ensure Aussies and their homes are better-prepared to weather future storms.
“Building a collaborative and close-working relationship with other researchers working on related infrastructure resilience projects is a practical way to expand and share knowledge and learnings at scale, and inform the development of more robust technical solutions to solve similar problems.”

Theme 3 RIIS Hub Research involves multiple universities in NSW (UNSW, UNSW Sydney, Western Sydney University) as well as QUT in Queensland. We note that this visit was made possible thanks to NSW Chief Scientist ‘RAAP’ funding.
Theme 3 RIIS Hub researchers are designing and applying:
• Modelling, simulations, and prognostics
• Predictive modelling simulation & performance assessment
• Physics-informed artificial intelligence (AI) and machine learning & explanation
