ParlaMint 4.1 is a set of comparable corpora containing transcriptions of parliamentary debates of 29 European countries and autonomous regions, mostly starting in 2015 and extending to mid-2022. The individual corpora comprise between 9 and 126 million words and the complete set contains over 1.2 billion words. The transcriptions are divided by days with information on the term, session and meeting, and contain speeches marked by the speaker and their role (e.g. chair, regular speaker). The speeches also contain marked-up transcriber comments, such as gaps in the transcription, interruptions, applause, etc. The corpora have extensive metadata, most importantly on speakers (name, gender, MP and minister status, party affiliation), on their political parties and parliamentary groups (name, coalition/opposition status, Wikipedia-sourced left-to-right political orientation, and CHES variables, https://www.chesdata.eu/). Note that some corpora have further metadata, e.g. the year of birth of the speakers, links to their Wikipedia articles, their membership in various committees, etc. The transcriptions are also marked with the subcorpora they belong to ("reference", until 2020-01-30, "covid", from 2020-01-31, and "war", from 2022-02-24). An overview of the statistics of the corpora is avaialable on GitHub in the folder Build/Metadata, in particular for the release 4.1 at https://github.com/clarin-eric/ParlaMint/tree/v4.1/Build/Metadata. The corpora are encoded according to the ParlaMint encoding guidelines (https://clarin-eric.github.io/ParlaMint/) and schemas (included in the distribution). The ParlaMint.ana linguistic annotation includes tokenization; sentence segmentation; lemmatisation; Universal Dependencies part-of-speech, morphological features, and syntactic dependencies; and the 4-class CoNLL-2003 named entities. Some corpora also have further linguistic annotations, in particular PoS tagging according a language-specific scheme, with their corpus TEI headers giving further details on the annotation ...
