InterCorp: Release 4

InterCorp is a large parallel synchronic corpus covering a number of languages. The corpus is compiled mostly by teachers and students of the Faculty of Arts, Charles University in Prague, and by other collaborators of the ICNC.

After registration here the corpus can be searched using a web interface. The registration is valid for all ICNC corpora with public access. If you already have a user name and password for the Czech part of the Czech National Corpus, you do not need to register for the parallel corpus.

There are several aspects that make InterCorp special among the corpora published by ICNC:

Texts in the corpus

The bulk of InterCorp consists of fiction in Czech and other languages, semi-automatically aligned, and a selection of political commentaries published by Project Syndicate and Presseurop. These texts have been aligned automatically: search results may include more misaligned segments.

Each text has a Czech counterpart. As a result, Czech is the pivot language: for every text there is a single Czech version (original or translation), aligned with one or more foreign-language versions. The total size of InterCorp as of September 2011 (InterCorp v. 4, see Version history) is 92 290 000 words in aligned foreign language texts. This number already includes Project Syndicate (approximately 2.3 - 3 million words in cs, de, en, es, fr, ru) and Presseurop (approximately 0.8 million words in cs, de, en, es, fr, it, nl, pl, pt, ro). The corpus composition can be seen in the following chart where the common title „beletrie“ („fiction“) denotes all manually aligned texts, mostly (but not exclusively) containing fiction. The bars show the size in millions of words.

Composition of the parallel corpora

The following table presents the sizes of parallel corpora in the individual languages. Numbers in each row show number of words in the given language (in thousands) which are also available in the language indicated by the column header. For instance, virtual Bulgarian-Croatian corpus contains 187 thousand words in Bulgarian (1st row - „bg“, 9th column - „hr“) and 189 thousand words in Croatian (9th row - „hr“, 1st column - „bg“). The second (highlighted) column shows the number of words aligned with Czech and thus also the overall size of the monolingual corpus of the language given on the corresponding row.
