Description

UD_Icelandic-Modern is a conversion of the modern additions to the Icelandic Parsed Historical Corpus (IcePaHC) to the Universal Dependencies scheme.

The conversion was done using UDConverter.

Note that the treebank data in versions 2.8-2.10 is flawed in that various sentences are duplicated, resulting in an overlap between train / dev / test. This issue has been fixed as of version 2.11.

The modern additions to the Icelandic Parsed Historical Corpus (IcePaHC) is a corpus which includes 21st-century texts NOT found in IcePaHC. These texts were manually parsed according to the Penn Parsed Corpora of Historical English (PPCHE) annotation scheme as used for IcePaHC. These parsed texts were then automatically converted to the Universal Dependencies scheme to create UD_Icelandic-Modern. The corpus consists of 80 thousand tokens in total. The texts are unprepared parliament speeches by four Icelandic members of parliament in the period 2011–2015 and sports news texts from two reporters at the Icelandic National Broadcasting Service (RÚV) from 2016 and – as of version 2.11 – from 2017. These 21st-century additions are not found in IcePaHC (which, however, contains two narrative texts from the 21st century).

Each sentence ID (sent_id) in UD_Icelandic-Modern carries the following information:

ALTHINGI_BO_2015_G-33-4647803,.1

Along with sentence IDs within the UD corpus, each sentence contains an X_ID flag, indicating the original sentence(s) in IcePaHC. This is useful as some sentences in the UD scheme have more than one original sentence in IcePaHC. As sentence IDs are currently not represented in the original parsed corpus found here, this flag is left blank, as ID_MISSING for each original sentence.

Manually corrected portion

A subset of the UD corpus has been manually corrected after the automatic conversion, 15,151 words in total. The portion corrected belonged to the following files, as shown in each sentence’s ID:
