InterCorp: Release 5

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:

• 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.
• InterCorp is unique in yet another aspect. Unlike most other ICNC corpora which are static (unchanged in time), InterCorp is incremental with its size and the number of languages growing.

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, and a package of legal texts Acquis Communautaire. These texts have been aligned automatically: search results may include a higher number of 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 the available part of InterCorp in release 5 (see Version history) is 91,529,000 words in the aligned foreign language texts in the core part and 451,112,000 in the collections. 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.

*) Each Czech text is counted only once, even though it may have more than one foreign counterpart.
