We are very pleased to announce that version 0.9 of the Icelandic
Parsed Historical Corpus (IcePaHC) is now available for free download.

The corpus can be downloaded from:
www.linguist.is/icelandic_treebank/Download

The corpus is a treebank of over 1 million words in size, annotated for
full phrase structure parse, and hand-corrected, using an adaptation of
the annotation scheme used by the Penn Treebank and the Penn
parsed corpora of historical English (http://www.ling.upenn.edu/hist-
corpora/). Note that this release contains all of the text for version 1.0,
but some minor corrections remain to be finished.

The corpus contains:

- 1 002 361 words total, consisting of ~100 000-word samples from
each century from the 12th to the beginnng of the 21st century.
- Annotated with a phrase structure parse, part-of-speech-tagged, and
lemmatized.
- The entire parse, pos-tagging, and lemmata for every sentence have
been *hand-corrected*.
- Text samples are balanced for genre within each century.
- LGPL license: You are free to copy, modify and redistribute the
corpus for research and/or profit with appropriate citation.

The corpus is distributed as raw UTF-8 data in labeled bracketing
format and it is therefore compatible with various existing programs,
including CorpusSearch (http://corpussearch.sourceforge.net/).

A plain text version without markup and a set of info files containing
philological information accompany the corpus download.

The entire corpus may be downloaded in a plain text version, a
platform-independent GUI, and a Windows-compatible GUI for ease of
searching.

Further information on the annotation guidelines and project
organization can be found on the project wiki:
