Corpora

  • Multi-lingual corpora & resources

(1)
If you can live with some noise, why not using Wikipedia? You can download a dump of the entire Wikipedia of the languages you need (without old version and images), e.g. http://dumps.wikimedia.org/etwiki/ for Estonian (replace ee in eewiki by the ISO language code of the other languages you need. Once you have the dump (XML file) you can extract the page tag which contains the WikiPage including the mediawiki syntax. The latter can be parsed with toolkits like http://sweble.org/ . I made the experience that very short pages are often stubs so they do not contribute “good” text to your corpus. Very long pages are often listings ( http://et.wikipedia.org/wiki/Maailma_riikide_loend ) too and therefore may not be adequate for your task. In order to parse the wiki syntax and get the text, several tools exist, for instance http://sweble.org .
(2)
texts published by the European Parliament
(3)
The Gutenberg project contains many books in several languages. http://www.gutenberg.org/wiki/Main_Page
(4)
Some other ideas for finding texts you might get checking OPUS: http://opus.lingfil.uu.se/ (parallel corpora)
(5)
Massive multi-lingual corpora:
Interkorp: http://ucnk.ff.cuni.cz/intercorp/
ParaSol: http://parasol.unibe.ch/
(6)
CLEF: (http://www.clef-initiative.eu) It may be a good starting point.
(7)
The NLTK (Python) toolkit includes corpora in several of the languages you are looking for (and several others), in a variety of genres. Languages that are included for sure are: English, Italian, Polish, I think there may also be Swedish and Hungarian as well, but I’m not 100% sure…. http://www.nltk.org/
You can also get the corpora without the rest of the NLTK tools: http://www.nltk.org/nltk_data/
(8)
At the JRC’s Language Technology page http://ipsc.jrc.ec.europa.eu/index.php?id=61, you find parallel corpora for all the languages you are searching for, and more.
(9)
Semantics-based Multilingual dictionary a thttp://laconec.com:8088/codemoi
(10)
Google’s Cross-Lingual Dictionary (GCLD) — Released: 2012.175M short, unique text strings that were used to refer to one of 7.6M Wikipedia articles (source:
http://ebiquity.umbc.edu/blogger/2012/05/19/google-releases-database-linking-strings-and-concepts/). The details of the data and how it was constructed are in an LREC 2012 paper by Valentin Spitkovsky and Angel Chang, A Cross-Lingual Dictionary for English Wikipedia Concepts (http://nlp.stanford.edu/pubs/crosswikis.pdf). Get the data here:http://www-nlp.stanford.edu/pubs/crosswikis-data.tar.bz2/.

1) you can access the Estonian corpora more comfortably at http://www.cl.ut.ee/korpused/segakorpus/ as these pages have also English versions.

There is also a quite comprehensive list of all sorts of resources for
Estonian (wordlists, biographical data collections, dialect data,

language corpora, etc) here: http://viki.keeleleek.ee/wiki/Eesti_keele_ressursside_loend
All descriptions are in estonian only now

you can get an access to quite a decent corpora of Finnish from The Language Bank of Finalnd. For that, however, you would need to register (which is pretty simple), link here: http://www.csc.fi/english/research/sciences/linguistics/index_html

  • Portuguese Brazilian

Two corpora of human-produced dialogue summaries. It will soon also present a set of tools for corpus segmentation and annotation (specifically tailored to dialogue summary annotation), along with publications and technical documents relating to the corpora: http://www.each.usp.br/norton/resdial/index_ing.html

  • Romanian

Here a few links for Romanian corpora:
• http://www.cse.unt.edu/~rada/downloads.html
• http://www.statmt.org/europarl/
• http://www.corpora.heliohost.org/download.html

  • Spanish

• Various corpora compiled by Real Academia Española, all containing both European and American texts: http://www.rae.es/recursos/banco-de-datos

  • Swedish

Probably, the biggest collection corpora for Swedish is Språkbanken (http://spraakbanken.gu.se/). It’s free and it’s concordance searching (http://spraakbanken.gu.se/korp/#?lang=en).

Some of the corpora can even be downloaded. Some of them are restricted but a lot of corpora are free. And most of the others are available as ‘sentence sets’ if the sentence is enough for you context wise (the texts are scrambled so that the sentence is intact, but not the entire text. Contact Språkbanken (http://spraakbanken.gu.se/eng/information/contact), if you would like some help picking out corpora!

  • Tatar

CORPUS OF WRITTEN TATAR: http://corpus.tatfolk.ru/index_en.php

  • Turkish

Taner Sezer says: I’m working on building Turkish corpora, and yet, I build four.
Respectively, they are composed of online newspapers and some other various websites (+491M tokens), Turkish Wikipedia (+47M tokens), a tweets corpus (2009-2011) composed of 1 million tweets (+13M tokens) and a small corpus of online newspapers (~500 thousand tokens).
Each corpus is PosTagged and they also include morphological tagging.
The small newspaper corpus has metada for year, genre and source. And tweets corpus has a new tag set including internet abbreviations, smileys, internet emphasis (the words where a character is written multiple times in order to emphasis the word in context) and misspelled words.
Turkish is one of the widely spoken languages. On the other hand, because of missing tools, software and lack of useable corpora for linguistic studies, Turkish take a backseat in computational linguistics.
To sum up, I’ll be very pleased if I may provide data for your study and help about Turkish as a native speaker.
