Summarization datasets from the KAS corpus KAS-Sum 1.0

Summarization datasets were created from the text bodies in the KAS 2.0 corpus (http://hdl.handle.net/11356/1448) and the abstracts from the KAS-Abs 2.0 corpus (http://hdl.handle.net/11356/1449). The monolingual slo2slo dataset contains 69,730 Slovene abstracts and Slovene body texts. The cross-lingual slo2eng dataset contains 52,351 Slovene body texts and English abstracts. It is suitable for building cross-lingual summarization models. Total number of words represent the sum of words in bodies, Slovene abstracts, and English abstracts. The files are stored in the same manner as the complete KAS corpus, i.e. in 1,000 directories with the same filename prefix as in KAS. They are in the JSON format that contains chapter segmented text. In addition to a unique chapter ID, each JSON file contains a key titled “abstract” that contains a list with abstract text as its first element. The file with the metadata for the corpus texts is also included. The datasets are suitable for training monolingual Slovene summarization models and cross-lingual Slovene-English summarization models on long texts.
