Developing a Web-Based Stimulus Selection Hub for Anomia Treatment Using R and Shiny
Published:
The aim of this study was to develop a web-based tool that could be used by clinicians and researchers to obtain a variety of commonly used psycholinguistic properties of words. This would provide a one-stop-shop approach for users, particularly those who may not have the coding and data scraping skills or the time available for data extraction and comparison.

Improving Precision of Grammatical Error Correction with a Cheat Sheet
Published in Proceedings of the 14th Workshop on Innovative Use of NLP for Building Educational Applications, 2019
In this paper, we explore two approaches of generating error-focused phrases and examine whether these phrases can lead to better performance in grammatical error correction.

Semantic Diversity in Paired-Associate Learning: Further Evidence for the Information Accumulation Perspective of Cognitive Aging
Published in Psychonomic Bulletin & Review, 2020
The current study used a within-subject design in order to examine the influence of linguistic experience on paired associate learning in younger and older adults. Linguistic experience was modeled using a semantic diversity measure of word strength. When frequency is controlled for, high semantic diversity words are associated to a greater number of words and have a higher average strength of association. In the current study, PAL performance of older adults was significantly lower for word pairs involving high semantic diversity words, while their performance did not differ for low semantic diversity words, consistent with the information accumulation perspective of aging.

Improving Automatic Grammatical Error Annotation for Chinese Through Linguistically-Informed Error Typology
Published in Proceedings of the 31st International Conference on Computational Linguistics, 2025
This paper introduces improvements to automatic grammatical error annotation for Chinese. Our refined framework addresses language-specific challenges that cause common spelling errors in Chinese, including pronunciation similarity, visual shape similarity, specialized participles, and word ordering.

Refined Evaluation for End-to-End Grammatical Error Correction Using an Alignment-Based Approach
Published in Proceedings of the 31st International Conference on Computational Linguistics, 2025
We propose a refined alignment-based method to assess end-to-end grammatical error correction (GEC) systems, aiming to reproduce and improve results from existing evaluation tools, such as ERRANT, even when applied to raw text input—reflecting real-world language learners’ writing scenarios.

A Network Analysis of the Semantic Evolution of ‘Fruit’ and ‘Stone’ in Tibeto-Burman Languages
Published in Poznan Studies in Contemporary Linguistics, 2025
The lexemes ‘fruit’ and ‘stone’ are known as the origins of the numeral classifiers for small round objects in many Tibeto-Burman languages. This paper employs a correlation-based network construction method to investigate the colexification networks of the two concepts in 58 + 68 Tibeto-Burman languages.

Bias in Large Language Models: Origin, Evaluation, and Mitigation
Published in Electronics, 2026
Large language models (LLMs) have revolutionized natural language processing, but their susceptibility to biases poses significant challenges. This comprehensive review examines the landscape of bias in LLMs, from its origins to current mitigation strategies. By synthesizing current knowledge on bias in LLMs, this review contributes to the ongoing effort to develop fair and responsible artificial intelligence (AI) systems.
