Introducing a New CLARIN-LT Resource: The SIMAS Corpus

In May 2025, the Morphologically and Syntactically Annotated Corpus SIMAS was deposited in the CLARIN-LT repository.  This is part of the European Union’s NextGenerationEU project “Morphologically and syntactically annotated text models for training (gold standards)” (No. 02-098-K-0001) carried out by the Institute of Digital Resources and Interdisciplinary Research (SITTI) at Vytautas Magnus University (VMU). Project leader: Assoc. Prof. Erika Rimkutė. This project fosters technological innovation in the Lithuanian language and offers tangible benefits to the public, government agencies, and the business sector (additional information is available here).

The “SIMAS” corpus comprises original texts across various genres, including fiction, academic writing, administrative texts, and journalism, all authored by Lithuanian writers from 2005 to 2025. This corpus is composed of complete texts rather than text fragments. The corpus underwent automatic morphological and syntactic annotation, followed by a review conducted by linguists. Automatic morphological annotation was performed using the tool Morfuoklis. Automatic syntactic parsing was conducted utilising the international tool UDPipe. The corpus is annotated according to the international Universal Dependencies (UD) standard, the morphological annotation standard Jablonskis, and for syntactic analysis, the Universal Dependencies Standard: the Lithuanian Syntactic Annotation Guidelines. Corpus size: 10,010,420 words (or 12,221,575 tokens).

Additionally, the VMU Faculty of Humanities website features an article by Miglė Žemrietė, Morphologically and Syntactically Annotated Lithuanian Corpus SIMAS, which discusses the necessity of technological resources for the Lithuanian language and the significance of various technological projects for Lithuania.
