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 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.

InterCorp can be accessed via a standard web browser in two ways:

• InterCorp can be accessed via a standard web browser from the integrated search interface of the Czech National Corpus KonText. A tutorial is available in Czech and a brief summary also in English.
• From Park, a purpose-built interface. A brief user manual is available here.

Both search interfaces are based on the Manatee corpus engine and access identical texts. Park can also be used to search the previous version of the corpus.

Unlike most other ICNC corpora which are static (unchanged in time), InterCorp is incremental. With each new release, its size, or even the number of languages and the extent and quality of annotation may grow.

## Texts in the corpus

The core of InterCorp consists mostly of fiction, manually aligned. Intercorp offers also a selection of fully automatically processed texts, so-called collections. The current choice includes political commentaries published by Project Syndicate and Presseurop, a package of legal texts of the European Union form the Acquis Communautaire corpus, and proceedings of the European Parliament dated 2007–2011 from the Europarl corpus. These texts have been aligned automatically: search results may include a higher number of misaligned segments. Some texts from the Acquis Communautaire a Europarl corpora have been partially corrected or omitted – as a result, they may differ in form or size if compared with the original source. Moreover, even some core texts in the current release no. 6 are temporarily aligned only automatically without manual checking. This concerns a part of texts acquired from ASPAC – Amsterdam Slavic Parallel Aligned Corpus. Alignment of these texts will be checked and corrected before the next release.

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 the available part of InterCorp in release 6 from April 2013 is 138,779,000 words in the aligned foreign language texts in the core part and 728,508,000 in the collections (see Version history). The share of the core and the collections in the corpus can be seen in the following chart. The size is shown in millions of words.
