The MARCELL corpus includes 7 monolingual sub-corpora (Bulgarian, Croatian, Hungarian, Polish, Romanian, Slovak and Slovenian) containing the total body of respective national legislative documents. These sub-corpora are automatically sentence split, tokenized, lemmatized and morphologically and syntactically annotated. The monolingual sub-corpora are complemented by a thematically related parallel corpus (Croatian-English). The metadata and the annotations are uniformly provided for each language specific sub-corpus. Besides the standard morphosyntactic analysis plus named entity and dependency and/or noun phrase annotation, the corpus is enriched with the IATE and EuroVoc labels. The file format is CoNLL-U Plus Format, containing the ten columns specific to the CoNLL-U format and four extra columns specific to our corpora. The MARCELL corpora represent a rich and valuable source for further studies and developments in machine learning, cross-lingual terminological data extraction and classification. Keywords: law corpus, comparable corpus, under-resourced languages 1. Introduction The present paper introduces the MARCELL corpus and related resources compiled in the CEF Telecom1 Action of the same name. The CEF Telecom project Multilingual Resources for CEF.AT in the Legal Domain (MARCELL)2 aims to enhance the eTranslation system3 developed by the European Commission through supplying seven large scale corpora consisting of national legislative documents effective in Bulgaria, Croatia, Hungary, Poland, Romania, Slovakia and Slovenia. The structure of the paper is as follows. We describe the rationale and objectives of the work in section 2. The composition of the corpus in each of the seven languages is presented in 3, whereas section 4 introduces the Croatian̶ English parallel corpus, also created in the project. The format and annotation, as well as the metadata of the multilingual corpora are described in sections 5 and 6 respectively. In some languages the corpus is already enriched with annotation of terminology in IATE4 and EuroVoc5 as described in section 7, the annotation work is still in progress for the rest of the languages. The multilingual corpus will be subdivided into several sub- domains corresponding to top-level categories of the 1https://ec.europa.eu/inea/en/connecting-europe-facility/cef- telecom 2 http://marcell-project.eu 3https://ec.europa.eu/cefdigital/wiki/display/CEFDIGITAL/eTra nslation 4 https://iate.europa.eu/home EuroVoc system.
