From News to Summaries: Building a Hungarian Corpus for Extractive and Abstractive Summarization
This addresses the problem of limited resources for Hungarian summarization, though it is incremental as it adapts existing methods to a new language.
The paper tackles the scarcity of training data for summarization models in Hungarian by introducing HunSum-2, an open-source corpus for extractive and abstractive summarization, and trains baseline models with quantitative and qualitative evaluation.
Training summarization models requires substantial amounts of training data. However for less resourceful languages like Hungarian, openly available models and datasets are notably scarce. To address this gap our paper introduces HunSum-2 an open-source Hungarian corpus suitable for training abstractive and extractive summarization models. The dataset is assembled from segments of the Common Crawl corpus undergoing thorough cleaning, preprocessing and deduplication. In addition to abstractive summarization we generate sentence-level labels for extractive summarization using sentence similarity. We train baseline models for both extractive and abstractive summarization using the collected dataset. To demonstrate the effectiveness of the trained models, we perform both quantitative and qualitative evaluation. Our dataset, models and code are publicly available, encouraging replication, further research, and real-world applications across various domains.
