Math2Visual-X: A Modular Framework for Pedagogically Aligned Lower-Primary Math Visuals Generation
H. D. E. Maduranga, S. K. Munasinghe, K. P. T. I. Weerasekara +2
Visual representations can help lower-primary learners understand Math Word Problems, but generating classroom-usable visuals remains difficult. Existing symbolic systems are contr…
TripleBound: Triplet-Guided Heterogeneous Graph Learning for Microservice Decomposition
Mineth Weerasinghe, Himindu Kularathne, Methmini Madhushika +4
Cloud computing and DevOps have made microservices a common architecture for scalable, maintainable software systems. However, migrating monoliths to microservices remains challeng…
Dynamics of Meaning: Towards the Evaluation of Diachronic Semantic Change in Sinhala
Nevidu Jayatilleke, Nisansa de Silva
Tracking semantic change in low-resource languages across extensive historical timelines presents significant challenges due to data scarcity and the limitations of static embeddin…
Confident but Wrong: A Constrained Decoding Diagnostic for Low-Resource Automatic Post-Editing
Isuru Wijesiri, Nisansa de Silva, Kavindu Warnakulasuriya +2
Automatic Post-Editing (APE) for low-resource languages (LRLs) often fails to improve Machine Translation (MT), and the score alone cannot say why: whether more training would help…
Forecasting Weather-Driven Price Dynamics Across Sri Lankan Tea Market Catalogues
Hesandi Mallawarachchi, Senilka Madurapperumage, Nadil Kulathunge +6
The Colombo Tea Auction (CTA) plays a vital role in determining global tea prices, yet the relationship between local weather conditions and price behavior across different tea cat…
EnSiTa - A Trilingual Multi-Domain Parallel Dataset and Benchmark for Domain-Specific Machine Translation
Surangika Ranathunga, Nisansa de Silva, Aloka Fernando +8
Machine Translation (MT) for low-resource languages remains far behind that of high-resource languages, and the gap is widest in specialised domains, where parallel data is scarce…
HelaBERT: Enhancing Sinhala Language Understanding with Dual Pooling Classification Head
Thisen Ekanayake, Nisansa de Silva
We present HelaBERT, a family of two BERT-based masked language models pre-trained from scratch on approximately 1 billion tokens of Sinhala text sourced from MADLAD-400, CulturaX,…
Semantics of Subterfuge: Benchmarking Legal Deception Detection Against General-domain State-of-the-Art
Theekshana Samaradiwakara, Nisansa de Silva, George C. Lobb
Deception detection has critical implications for legal proceedings, law enforcement, and online security. Although human judgment is limited in accuracy and scalability, Natural L…
SalAngaBhava: A Sinhala Market Dataset for Aspect-based Sentiment Analysis
Lakshani Galwatta, Nisansa de Silva, Sarangi Aththanayake +1
Sentiment analysis has been a primary domain under Natural Language Processing (NLP) from its inception as it plays a vital role in both real-world and research applications. In hi…
Section-Weighted Hybrid Approach for Legal Case Retrieval
Rajith Arulanandam, Nisansa de Silva
Finding truly analogous precedents requires capturing legal reasoning beyond surface word overlap. We present a two-stage, section-aware framework for legal case retrieval that fir…
From Monolith to Microservices: A Comparative Evaluation of Decomposition Frameworks
Mineth Weerasinghe, Himindu Kularathne, Methmini Madhushika +4
Software modernisation through the migration from monolithic architectures to microservices has become increasingly critical, yet identifying effective service boundaries remains a…
