Real-word spelling errors (RWSEs) pose special challenges for detection methods, as they ‘hide&#39; in the form of another existing word and in many cases even fit in syntactically. We present a modern Transformer-based implementation of earlier probabilistic methods based on confusion sets and show that RWSEs can be detected with a good balance between missing errors and raising too many false
alarms. The confusion sets are dynamically configurable, allowing teachers to easily adjust which errors trigger feedback.

Welcome to The 63rd Annual Meeting of the Association for Computational Linguistics (ACL 2025)

Weakly supervised learning (WSL) is a machine learning approach used when labeled data is scarce or expensive to obtain. In such scenarios, models are trained using weaker supervision sources instead of human-annotated data. However, these sources are often noisy and may introduce unquantified biases during training. This issue is particularly pronounced in automated scoring (AS) of second language (L2) learner output, where high variability and limited generalizability pose significant challenges.
In this paper, we investigate analytical scoring of L2 learner responses under weak and semi-supervised learning conditions, leveraging Prediction-Powered Inference (PPI) to provide statistical guarantees on score validity. We compare two approaches: (1) synthetic scoring using large language models (LLMs), and (2) a semi-supervised setting in which a machine learning model, trained on a small gold-standard set, generates predictions for a larger unlabeled corpus. In both cases, PPI is applied to construct valid confidence intervals for assessing the reliability of the predicted scores.
Our analysis, based on a dataset of L2 learner conversations with an AI agent, shows that PPI is highly informative for evaluating the quality of weakly annotated data. Moreover, we demonstrate that PPI can increase the effective sample size by over 150% relative to the original human-scored subset, enabling more robust inference in educational assessment settings where labeled data is scarce.

Automated L2 Proficiency Scoring: Weak Supervision, Large Language Models, and Statistical Guarantees

Inference making is an essential but complex skill in reading comprehension (RC). Some inferences require resolving references across sentences, and some rely on using prior knowledge to fill in the detail that is not explicitly written in the text. Diagnostic RC questions can help educators provide more effective and targeted reading instruction and interventions for school-age students. We introduce a taxonomy of inference types for RC and use it to analyze the distribution of items within a diagnostic RC item bank. Next, we present experiments using GPT-4o to generate bridging-inference RC items for given reading passages via few-shot prompting, comparing conditions with and without chain-of-thought prompts. Generated items were evaluated on three aspects: overall item quality, appropriate inference type, and LLM reasoning, achieving high inter-rater agreements above 0.90. Our results show that GPT-4o produced 93.8% good-quality questions suitable for operational use in grade 3-12 contexts; however, only 42.6% of the generated questions accurately matched the targeted inference type. We conclude that combining automatic item generation with human judgment offers a promising path toward scalable, high-quality diagnostic RC assessments.

Automatic Generation of Inference Making Questions for Reading Comprehension Assessments

We present LangEye, a mobile application for contextual vocabulary learning that combines learner-curated content with generative NLP. Learners use their smartphone camera to capture real-world objects and create personalized "memories" enriched with definitions, example sentences, and pronunciations generated via object recognition, large language models, and machine translation. LangEye features a three-phase review system — progressing from picture recognition to sentence completion and free recall. In a one-week exploratory study with 20 French (L2) learners, the learner-curated group reported higher engagement and motivation than those using pre-curated materials. Participants valued the app's personalization and contextual relevance. This study highlights the potential of integrating generative NLP with situated, learner-driven interaction. We identify design opportunities for adaptive review difficulty, improved content generation, and better support for language-specific features. LangEye points toward scalable, personalized vocabulary learning grounded in real-world contexts.

We train a relative sentence readability estimator from a corpus without absolute sentence readability.
Since sentence readability depends on the reader's knowledge, objective and absolute readability assessments require costly annotation by experts.
Therefore, few corpora have absolute sentence readability, while parallel corpora for text simplification with relative sentence readability between two sentences are available for many languages.
With multilingual applications in mind, we propose a method to estimate relative sentence readability based on parallel corpora for text simplification.
Experimental results on ranking a set of English sentences by readability show that our method outperforms existing unsupervised methods and is comparable to supervised methods based on absolute sentence readability.

Unsupervised Sentence Readability Estimation Based on Parallel Corpora for Text Simplification

This study presents a teacher-centered evaluation of an AI-powered reading comprehension tool, developed to support learners with language-based difficulties. Drawing on the Social Acceptance of Technology (SAT) framework, we investigate not only technical usability but also the pedagogical, ethical, and contextual dimensions of AI integration in classrooms. We explore how teachers perceive the platform's alignment with inclusive pedagogies, instructional workflows, and professional values through a mixed-methods approach, including questionnaires and focus groups with educators. Findings a shift from initial curiosity to critical, practice-informed reflection, with trust, transparency, and adaptability emerging as central concerns. The study contributes a replicable evaluation framework and highlights the importance of engaging teachers as co-designers in the development of educational technologies.

From End-Users to Co-Designers: Lessons from Teachers

We release LORuGEC -- the first rule-annotated corpus for Russian Grammatical Error Correction. The corpus is designed for diagnostic purposes and contains 348 validation and 612 test sentences specially selected to represent complex rules of Russian writing. This makes our corpus significantly different from other Russian GEC corpora. We apply several large language models and approaches to our corpus, the best F0.5 score of 83% is achieved by 5-shot learning using YandexGPT-5 Pro model.

To move further the boundaries of few-shot learning, we are the first to apply a GECTOR-like encoder model for similar examples retrieval. GECTOR-based example selection significantly boosts few-shot performance. This result is true not only for LORuGEC but for other Russian GEC corpora as well. On LORuGEC, the GECTOR-based retriever might be further improved using contrastive tuning on the task of rule label prediction. All these results hold for a broad class of large language models.

LLMs in alliance with Edit-based models: advancing In-Context Learning for Grammatical Error Correction by Specific Example Selection

Comparative judgment (CJ) is an assessment method in which multiple assessors determine the holistic quality of essays through pairwise comparisons.
While CJ is recognized for generating reliable and valid scores, it falls short in providing transparency about the specific quality aspects these holistic scores represent.
Our study addresses this limitation by predicting scores on a set of rubrics that measure text quality, thereby explaining the holistic scores derived from CJ.
We developed feature-based machine learning models that leveraged complexity and genre features extracted from a collection of Dutch essays.
We evaluated the predictability of rubric scores for text quality based on linguistic features.
Subsequently, we evaluated the validity of the predicted rubric scores by examining their ability to explain the holistic scores derived from CJ.
Our findings indicate that feature-based prediction models can predict relevant rubric scores moderately well. Furthermore, the predictions can be used to explain holistic scores from CJ, despite certain biases. This automated approach to explain holistic quality scores from CJ can enhance the transparency of CJ assessments and simplify the evaluation of their validity.

Explaining Holistic Essay Scores in Comparative Judgment Assessments by Predicting Scores on Rubrics

Automated Essay Scoring (AES) plays a crucial role in assessing language learners' writing quality, reducing grading workload, and providing real-time feedback. The lack of annotated essay datasets inhibits the development of Arabic AES systems. This paper leverages Large Language Models (LLMs) and Transformer models to generate synthetic Arabic essays for AES. We prompt an LLM to generate essays across the Common European Framework of Reference (CEFR) proficiency levels and introduce and compare two approaches to error injection. We create a dataset of 3,040 annotated essays with errors injected using our two methods. Additionally, we develop a BERTbased Arabic AES system calibrated to CEFR levels. Our experimental results demonstrate the effectiveness of our synthetic dataset in improving Arabic AES performance. We make our code and data publicly available

Enhancing Arabic Automated Essay Scoring with Synthetic Data and Error Injection

Interviews are central to the Empathy phase of Design Thinking, helping designers uncover user needs and experience. Although interviews are widely used to support human centered innovation, evaluating their quality, especially from a cognitive perspective, remains underexplored. This study introduces a structured framework for evaluating interview quality in the context of Design Thinking, using Bloom's Taxonomy as a foundation. We propose the Cognitive Interview Quality Score, a composite metric that integrates three dimensions: Effectiveness Score, Bloom Coverage Score, and Distribution Balance Score. Using human-annotations, we assessed 15 interviews across three domains to measure cognitive diversity and structure. We compared CIQS-based rankings with human experts and found that the Bloom Coverage Score aligned more closely with expert judgments. We evaluated the performance of LMA-3-8B-Instruct and GPT-4o-mini, using zero-shot, few-shot, and chain-of-thought prompting, finding GPT-4o-mini, especially in zero-shot mode, showed the highest correlation with human annotations in all domains. Error analysis revealed that models struggled more with mid-level cognitive tasks (e.g., Apply, Analyze) and performed better on Create, likely due to clearer linguistic cues. These findings highlight both the promise and limitations of using NLP models for automated cognitive classification and underscore the importance of combining cognitive metrics with qualitative insights to comprehensively assess interview quality.

Analyzing Interview Questions via Bloom's Taxonomy to Enhance the Design Thinking Process

Large language models (LLMs) are increasingly being adopted in educational settings. These applications expand beyond English, though current LLMs remain primarily English-centric. In this work, we ascertain if their use in education settings in non-English languages is warranted. We evaluated the performance of popular LLMs on four educational tasks: identifying student misconceptions, providing targeted feedback, interactive tutoring, and grading translations in eight languages (Mandarin, Hindi, Arabic, German, Farsi, Telugu, Ukrainian, Czech) in addition to English. We find that the performance on these tasks somewhat corresponds to the amount of language represented in training data, with lower-resource languages having poorer task performance. However, at least some models are able to more or less maintain their levels of performance across all languages. Thus, we recommend that practitioners first verify that the LLM works well in the target language for their educational task before deployment.
