title: Romanian Named Entity Recognition in the Legal domain (LegalNERo)

description: LegalNERo is a manually annotated corpus for named entity recognition in the Romanian legal domain. <br> It provides gold annotations for organizations, locations, persons, time and legal resources mentioned in legal documents.<br> Additionally it offers GEONAMES codes for the named entities annotated as location (where a link could be established). The LegalNERo corpus is available in different formats: span-based, token-based and RDF. <br> The Linguistic Linked Open Data (LLOD) version is provided in RDF-Turtle format. CONLLUP files conform to the CoNLL-U Plus format https://universaldependencies.org/ext-format.html .<br> Part-of-speech tagging was realized using UDPIPE. <br> Named entity annotations are placed in the column "RELATE:NE" (the 11th column) as defined in the "global.columns" metadata field.<br> Similarly GEONAMES references are in the column "RELATE:GEONAMES" (the 12th column, last).<br> Automatic processing was performed through the RELATE platform (https://relate.racai.ro). ANN files conform to BRAT format (https://brat.nlplab.org/).<br> <br> The archive contains: - ann_LEGAL_PER_LOC_ORG_TIME_overlap <br> Folder in which all the files are in .ann format and contains annotations of: legal resources mentioned, persons, locations, organizations and time. <br> Overlapping annotations of organizations and time entities inside legal references were allowed. - ann_LEGAL_PER_LOC_ORG_TIME <br> Folder in which all the files are in .ann format and contains annotations of: legal resources mentioned, persons, locations, organizations and time. <br> Overlapping annotations were not allowed and only the longest named entities were annotated. - ann_PER_LOC_ORG_TIME <br> Folder in which all the files are in .ann format and contains annotations of: persons, locations, organizations and time. <br> There are no overlapping annotations. - conllup_LEGAL_PER_LOC_ORG_TIME <br> Folder in which all the files are in .conllup format and contains annotations of: legal resources mentioned, persons, locations, organizations and time. <br> Overlapping annotations were not allowed and only the longest named entities were annotated. <br> The annotation of these files was enhanced with GEONAMES codes (where linking was possible). - conllup_PER_LOC_ORG_TIME <br> Folder in which all the files are in .conllup format and contains annotations of: persons, locations, organizations and time. <br> Overlapping annotations were not allowed and only the longest named entities were annotated. <br> The annotation of these files was enhanced with GEONAMES codes (where linking was possible). - rdf <br> Folder containing the corpus in RDF-Turtle format.<br> All the annotations are available here in both span and token format. - text <br> Folder containing the raw texts. <br> LICENSING This work is provided under the license CC BY-NC-ND 4.0 (Attribution-NonCommercial-NoDerivatives 4.0 International).<br> The license can be viewed online here: https://creativecommons.org/licenses/by-nc-nd/4.0/ <br> and the full text here: https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode . <br> CONTACT Research Institute for Artificial Intelligence "Mihai Draganescu", Romanian Academy<br> Web: http://www.racai.ro <br> Contact emails: vasile@racai.ro , maria@racai.ro
