RoCulturaMCQ: Building a Benchmark While Learning Statistics

The broad adoption of Large Language Models (LLMs) has increased the need for human-curated datasets that serve as evaluation benchmarks. This need is particularly pronounced for non-English languages and for tasks that are inherently subjective and require multiple human perspectives. One such example is the development of benchmarks designed to assess the cultural awareness of LLMs. Statistics and data science courses offer a potential setting for developing such benchmarks while teaching students to apply LLM evaluation techniques using statistical inference. This paper presents a pilot project in which students in a statistics course within a data science engineering program created culturally diverse multiple-choice questions, generated answers using LLMs, and applied statistical methods to assess model accuracy. Student feedback indicated the project was engaging and useful for learning, while also highlighting a notable reliance on LLMs, particularly for interpreting statistical results. The resulting dataset comprises 1355 multiple-choice questions across 18 categories, including language, social media, and politics. After filtering valid items, the dataset was used to evaluate both closed- and open-source LLMs. Results show that the Gemini (closed-source) and Qwen (open-source) model families achieved the best performance, with improvements linked to model size, reasoning capabilities, and access to search tools. The best closed-source model achieved an accuracy of 97.66%, whereas the best open-source model achieved an accuracy of 79.07%. Qualitative analyses of errors in the filtering procedure and model reasoning process point to possible explanations into the challenges LLMs face when handling culturally specific content. Furthermore, results support a cultural injection hypothesis, whereby cultural knowledge is embedded during pretraining and accessed through instruction tuning. Through this work, we aim to demonstrate how statistics and data science courses can provide productive contexts for developing open-source benchmarks for non-English languages while also enriching students’ learning experiences. The dataset is publicly available.

FroLineR: Front-Line Response with Retrieval-Augmented Prompt-Engineered Reply Generation for IT Help Desks

IT help desks at large organizations face a high volume of recurrent, well-documented user requests that nevertheless require human-written replies, creating a persistent staff workload that is repetitive in content but non-trivial in tone and procedural correctness. We present FroLineR, short for Front-Line Response, a system that drafts the initial staff reply to such tickets in the login and account-activation category and integrates into a human-in-the-loop ticketing workflow on a Romanian-language ticketing platform. The generator is an unmodified instruct model augmented with retrieval from a small set of hand-curated guide documents, using a Romanian system prompt refined over several rounds of staff review. To evaluate and refine the prompt without manual labeling, we cluster the first user message of every historical thread with both BERTopic and Semantic Signal Separation (S3), score configurations along coherence and lexical-diversity axes, and extract a 200-message evaluation set from the winning model. Prompt convergence was certified by several rounds of manual review by support staff. The production system is quantized to Q4_K_M GGUF, served through llama-cpp-python behind a small Flask API, and deployed with GPU offloading on the target server, reducing end-to-end per-answer latency from approximately 830 s on the server’s CPU to roughly 61 s once layers are offloaded to the GPU, with no observable degradation in answer quality.
