EduAssist: Evaluating a Locally Deployed Large Language Model for Educational Document Summarization
TL;DR
E EduAssist, an experimental framework for evaluating a locally deployed Qwen3:1.7B model for educational document summarization, provides exploratory empirical evidence for the feasibility of local educational document summarization using the evaluated Qwen3:1.7B configuration while highlighting the need for larger datasets, model comparisons, independent reference summaries, and human evaluation.
Abstract
The increasing use of large language models (LLMs) for educational text processing has created opportunities for automatic summarization of lengthy learning materials. However, many LLM-based applications rely on cloud-hosted services, while the performance and computational behavior of locally deployed language models for educational document summarization remain comparatively underexplored. This study presents EduAssist, an experimental framework for evaluating a locally deployed Qwen3:1.7B model for educational document summarization. The model was executed through the Ollama runtime using a chunk-based summarization and consolidation pipeline. Experiments were conducted on 12 English-language educational samples covering topics in data mining, machine learning, artificial intelligence, and knowledge-based systems. Evaluation combined text-reduction and efficiency measures with lexical, semantic, and model-assisted assessment using compression ratio, estimated reading-time reduction, processing time, source-reference ROUGE, BERTScore, and LLM-as-a-Judge. The generated summaries achieved a mean compression ratio of 50.83%, reducing the mean source length from 1,074.17 to 478.42 words and yielding an estimated mean readingtime saving of 2.98 min. Mean ROUGE-1, ROUGE-2, and ROUGE-L scores were 0.4917, 0.2371, and 0.2892, respectively, while the mean BERTScore F1 was 0.8264 and the mean LLM-as-a-Judge score was 7.96/10. Summary generation required an average of 194.33 s per sample. Exploratory analysis further showed that greater compression was associated with lower source-reference lexical retention, whereas source-summary BERTScore F1 values remained comparatively stable across the evaluated samples. Overall, the findings provide exploratory empirical evidence for the feasibility of local educational document summarization using the evaluated Qwen3:1.7B configuration, while highlighting the need for larger datasets, model comparisons, independent reference summaries, and human evaluation.
