This study explores the application of Large Language Models (LLMs) and supervised learning to analyze social media posts from Reddit users, addressing two key objectives: first, to extract adaptive and maladaptive self-state evidence that supports psychological assessment (Task A1); and second, to predict a well-being score that reflects the user’s mental state (Task A2). We propose i) a fine-tuned RoBERTa (Liu et al., 2019) model for Task A1 to identify self-state evidence spans and ii) evaluate two approaches for Task A2: a retrieval-augmented DeepSeek-7B (DeepSeek-AI et al., 2025) model and a Random Forest regression model trained on sentence embeddings. While LLM-based prompting utilizes contextual reasoning, our findings indicate that supervised learning provides more reliable numerical predictions. The RoBERTa model achieves the highest recall (0.602) for Task A1, and Random Forest regression outperforms DeepSeek-7B for Task A2 (MSE: 2.994 vs. 6.610). These results highlight the strengths and limitations of generative vs. supervised methods in mental health NLP, contributing to the development of privacy-conscious, resource-efficient approaches for psychological assessment. This work is part of the CLPsych 2025 shared task (Tseriotou et al., 2025).

Predicting the duration of a patient’s stay in an Intensive Care Unit (ICU) is a critical challenge for healthcare administrators, as it impacts resource allocation, staffing, and patient care strategies. Traditional approaches often rely on structured clinical data, but recent developments in language models offer significant potential to utilize unstructured text data such as nursing notes, discharge summaries, and clinical reports for ICU length-of-stay (LoS) predictions. In this study, we introduce a method for analyzing nursing notes to predict the remaining ICU stay duration of patients. Our approach leverages a joint model of latent note categorization, which identifies key health-related patterns and disease severity factors from unstructured text data. This latent categorization enables the model to derive high-level insights that influence patient care planning. We evaluate our model on the widely used MIMIC-III dataset, and our preliminary findings show that it significantly outperforms existing baselines, suggesting promising industrial applications for resource optimization and operational efficiency in healthcare settings.

Across countries, a noteworthy paradigm shift towards a more sustainable and environmentally responsible economy is underway. However, this positive transition is accompanied by an upsurge in greenwashing, where companies make exaggerated claims about their environmental commitments. To address this challenge and protect consumers, initiatives have emerged to substantiate green claims. With the proliferation of environmental and scientific assertions, a critical need arises for automated methods to detect and validate these claims at scale. In this paper, we introduce EnClaim, a transformer network architecture augmented with stylistic features for automatically detecting claims from open web documents or social media posts. The proposed model considers various linguistic stylistic features in conjunction with language models to predict whether a given statement constitutes a claim. We have rigorously evaluated the model using multiple open datasets. Our initial findings indicate that incorporating stylistic vectors alongside the BERT-based language model enhances the overall effectiveness of environmental claim detection.

Persons with severe speech and motor impairments (SSMI), like those with cerebral palsy (CP) experience significant challenges via communication in conventional methods. Many a times they rely on Graphical symbol-based Augmentative and Alternative Communication (AAC) systems to facilitate the communication. Our work aims to support AAC communication by developing specialized datasets for direct translation of Graphical Symbols to Natural Language text. The dataset is enhanced with an automated Text-to-Pictogram generation module. The dataset is enriched with some additive information like tense-based information and subjective information (questionnaires, exclamations). Additionally, we expanded our efforts to include translation into Indian language Bengali, for those individuals with SSMI who are more comfortable communicating in their native language. We aim to develop an end-to-end language agnostic framework for efficient bidirectional communication between non-verbal AAC picture symbols and textual data.

In recent decades, environmental pollution has become a pressing global health concern. According to the World Health Organization (WHO), a significant portion of the population is exposed to air pollutant levels exceeding safety guidelines. Cardiovascular diseases (CVDs) — including coronary artery disease, heart attacks, and strokes — are particularly significant health effects of this exposure. In this paper, we investigate the effects of air pollution on cardiovascular health by constructing a dynamic knowledge graph based on extensive biomedical literature. This paper provides a comprehensive exploration of entity identification and relation extraction, leveraging advanced language models. Additionally, we demonstrate how in-context learning with large language models can enhance the accuracy and efficiency of the extraction process. The constructed knowledge graph enables us to analyze the relationships between pollutants and cardiovascular diseases over the years, providing deeper insights into the long-term impact of cumulative exposure, underlying causal mechanisms, vulnerable populations, and the role of emerging contaminants in worsening various cardiac outcomes.

In this paper we propose a framework for automatic translation of English text to American Sign Language (ASL) which leverages a linguistically informed transformer model to translate English sentences into ASL gloss sequences. These glosses are then associated with respective ASL videos, effectively representing English text in ASL. To facilitate experimentation, we create an English-ASL parallel dataset on banking domain.Our preliminary results demonstrated that the linguistically informed transformer model achieves a 97.83% ROUGE-L score for text-to-gloss translation on the ASLG-PC12 dataset. Furthermore, fine-tuning the transformer model on the banking domain dataset yields an 89.47% ROUGE-L score when fine-tuned on ASLG-PC12 + banking domain dataset. These results demonstrate the effectiveness of the linguistically informed model for both general and domain-specific translations. To facilitate parallel dataset generation in banking-domain, we choose ASL despite having limited benchmarks and data corpus compared to some of the other sign languages.

The escalating prevalence of food safety incidents within the food supply chain necessitates immediate action to protect consumers. These incidents encompass a spectrum of issues, including food product contamination and deliberate food and feed adulteration for economic gain leading to outbreaks and recalls. Understanding the origins and pathways of contamination is imperative for prevention and mitigation. In this paper, we introduce FORCE Foodborne disease Outbreak and ReCall Event extraction from openweb). Our proposed model leverages a multi-tasking sequence labeling architecture in conjunction with transformer-based document embeddings. We have compiled a substantial annotated corpus comprising relevant articles published between 2011 and 2023 to train and evaluate the model. The dataset will be publicly released with the paper. The event detection model demonstrates fair accuracy in identifying food-related incidents and outbreaks associated with organizations, as assessed through cross-validation techniques.

Obtaining demand trends for products is an essential aspect of supply chain planning. It helps in generating scenarios for simulation before actual demands start pouring in. Presently, experts obtain this number manually from different News sources. In this paper, we have presented methods that can automate the information acquisition process. We have presented a joint framework that performs information extraction and sentiment analysis to acquire demand related information from business text documents. The proposed system leverages a TwinBERT-based deep neural network model to first extract product information for which demand is associated and then identify the respective sentiment polarity. The articles are also subjected to causal analytics, that, together yield rich contextual information about reasons for rise or fall of demand of various products. The enriched information is targeted for the decision-makers, analysts and knowledge workers. We have exhaustively evaluated our proposed models with datasets curated and annotated for two different domains namely, automobile sector and housing. The proposed model outperforms the existing baseline systems.

The number of assistive technologies available for dyslexia in Bangla is low and most of them do not use multisensory teaching methods. As a solution, a computer-based audio-visual system Dy-poThon is proposed to teach sentence reading in Bangla. It incorporates the multisensory teaching method through three activities, listening, reading, and writing, checks the reading and writing ability of the user and tracks the response time. A criteria-based evaluation was conducted with 28 special educators to evaluate Dy-poThon. Content, efficiency, ease of use and aesthetics are evaluated using a standardised questionnaire. The result suggests that Dy-poThon is useful for teaching Bangla sentence-reading.

In this paper we have developed an open-source online computational framework that can be used by different research groups to conduct reading researches on Indian language texts. The framework can be used to develop a large annotated Indian language text comprehension data from different user based experiments. The novelty in this framework lies in the fact that it brings different empirical data-collection techniques for text comprehension under one roof. The framework has been customized specifically to address language particularities for Indian languages. It will also offer many types of automatic analysis on the data at different levels such as full text, sentence and word level. To address the subjectivity of text difficulty perception, the framework allows to capture user background against multiple factors. The assimilated data can be automatically cross referenced against varying strata of readers.
