Machine translation (MT) systems that support low-resource languages often struggle on specialized domains. While researchers have proposed various techniques for domain adaptation, these approaches typically require model fine-tuning, making them impractical for non-technical users and small organizations. To address this gap, we propose Tulun, a versatile solution for terminology-aware translation, combining neural MT with large language model (LLM)-based post-editing guided by existing glossaries and translation memories.
Our open-source web-based platform enables users to easily create, edit, and leverage terminology resources, fostering a collaborative human-machine translation process that respects and incorporates domain expertise while increasing MT accuracy.
Evaluations show effectiveness in both real-world and benchmark scenarios: on medical and disaster relief translation tasks for Tetun and Bislama, our system achieves improvements of 16.90-22.41 ChrF++ points over baseline MT systems. Across six low-resource languages on the FLORES dataset, Tulun outperforms both standalone MT and LLM approaches, achieving an average improvement of 2.8 ChrF points over NLLB-54B. Tulun is publicly accessible at https://bislama-trans.rapha.dev.

DEEP is a bidirectional translation system for the Italian Sign Language, tailored to two specific, common use cases: pharmacy and the registry office of the municipality, for which a custom corpus has been collected. Two independent pipelines permit to create a chat-like interaction style, where the deaf subject just signs in front of a camera, and see a virtual LIS interpreter, while the hearing subject read and write messages into a chat UI. The LIS-to-Italian pipeline leverages, in a novel way, a customized Whisper model (a well-known speech recognition system), by means of "pseudo-spectrograms''. The Italian-to-LIS pipeline leverages a virtual avatar created with Viggle.ai. DEEP has been evaluated with LIS signers, obtaining very promising results.

Despite the remarkable performance of Large Language Models (LLMs) in automated discharge summary generation, they still suffer from generating inaccurate content or fabricating information without valid sources. To address these issues, we propose LCDS, a tool for empowering LLMs with Logic-Controlled Discharge Summary generation. LCDS constructs a source mapping table by calculating the textual similarity between electronic medical records (EMRs) and discharge summaries, providing a structured reference for generation. Based on a comprehensive set of logical rules, LCDS identifies the structured writing logic of discharge summaries and integrates it with EMRs to generate silver discharge summaries. Furthermore, LCDS traces the provenance of generated content, allowing experts to review, provide feedback, and rectify errors to produce golden discharge summaries, which are subsequently recorded for the incremental fine-tuning of LLMs.
Our project and demo video are in the GitHub repository https://github.com/ycycyc02/LCDS.

LCDS: A Logic-Controlled Discharge Summary Generation System Supporting Source Attribution and Expert Review

The study of generalization in Language Models (LMs) requires controlled experiments that can precisely measure complex linguistic variations between training and testing datasets. We introduce DECAF, a framework that enables the analysis and filtering of linguistically-annotated datasets down to the character level. Rather than creating new resources for each experiment, DECAF starts from datasets with existing linguistic annotations, and leverages them to analyze, filter, and generate highly controlled and reproducible experimental settings targeting specific research questions. We demonstrate DECAF's functionality by adding full morphology and dependency annotations to the 131M-token BabyLM corpus and indexing the resulting 1.1B annotations to analyze its internal domain variance, and to create a controlled training data curriculum for a small-scale gender bias study. We release DECAF as a fully open-source Python library, along with the parsed and indexed version of BabyLM, as resources for future generalization research.

We introduce FORG3D, a 3D rendering toolkit developed with Blender and Python, which synthesizes vision-language data for two primary purposes: (1) supporting human cognitive experiments that require fine-grained control over material and (2) analyzing and improving the visual reasoning capabilities of large vision-language models. The toolkit provides flexible and precise control over object placement, orientation, inter-object distances, and camera configurations while automatically generating detailed spatial metadata. Additionally, it includes a built-in feature for integrating AI-generated backgrounds, enhancing the realism of synthetic scenes. FORG3D is publicly available at https://github.com/compling-wat/FORG3D, and a video demonstration is available at https://www.youtube.com/watch?v=QvIqib_PU8A.

While small language models (SLMs) show promises for mobile deployment, their real world performance and applications on smartphones remain underexplored. We present SlimLM, a series of SLMs optimized for document assistance tasks on mobile devices. Through extensive experiments on a Samsung Galaxy S24, we identify the sweet spot between model size (ranging from 125M to 8B parameters), context length, and inference time for efficient on-device processing. SlimLM is pretrained on SlimPajama-627B and fine-tuned on DocAssist, our constructed dataset for summarization, question answering, and suggestion tasks. Our smallest model demonstrates efficient performance on S24, while larger variants offer enhanced capabilities within mobile constraints. We evaluate SlimLM against existing SLMs, showing comparable or superior performance and offering a benchmark for future research in on-device language models. We provide an Android application allowing users to experience SlimLM’s document assistance capabilities, offering valuable insights for mobile developers, researchers, and companies seeking privacy-preserving on-device alternatives to server-based language models.

SlimLM: An Efficient Small Language Model for On-Device Document Assistance

Large Language Models (LLMs) have reshaped code generation by synergizing their exceptional comprehension of natural language and programming syntax, thereby substantially boosting developer productivity. These advancements have prompted numerous efforts to quantitatively evaluate their coding capabilities. However, persistent challenges, such as benchmark leakage, data dissipation, and limited system accessibility, continue to impede a timely and accurate assessment. To address these limitations, we introduce CodeArena, an online evaluation framework tailored for LLM code generation. Its key innovation is a collective evaluation mechanism, which dynamically recalibrates individual model scores based on the holistic performance of all participating models, mitigating score biases caused by widespread benchmark leakage. In addition, CodeArena ensures open access to all submitted solutions and test cases and provides automation-friendly APIs to streamline the code evaluation workflow. Our main contributions are: (1) a collective evaluation system for unbiased assessment, (2) a public repository of solutions and test cases, and (3) automation-ready APIs for seamless integration.

The swift advancement of Large Language Models (LLMs) has led to their widespread use across various tasks and domains, demonstrating remarkable generalization capabilities. However, achieving optimal performance in specialized tasks often requires fine-tuning LLMs with task-specific resources. The creation of high-quality, human-annotated datasets for this purpose is challenging due to financial constraints and the limited availability of human experts. To address these limitations, we propose First-AID, a novel Human-in-the-Loop (HITL) data collection framework for the knowledge-driven generation of synthetic dialogues using LLM prompting. In particular, our framework implements different strategies of data collection that require different user intervention during dialogue generation to reduce post-editing efforts and enhance the quality of generated dialogues. We also evaluated First-AID on misinformation and hate countering dialogues collection, demonstrating (1) its potential for efficient and high-quality data generation and (2) its adaptability to different practical constraint thanks to the three data collection strategies.

We introduce FlagEval-Arena, an evaluation platform for side-by-side comparisons of large language models and text-driven AIGC systems.Compared with the well-known LM Arena (LMSYS Chatbot Arena), we reimplement our own framework with the flexibility to introduce new mechanisms or features. Our platform enables side-by-side evaluation not only for language models or vision-language models, but also text-to-image or text-to-video synthesis. We specifically target at Chinese audience with a more focus on the Chinese language, more models developed by Chinese institutes, and more general usage beyond the technical community. As a result, we currently observe very interesting differences from usual results presented by LM Arena. Our platform is available via this URL: \url{https://flageval.baai.org/#/arena}.
