Slovak-Czech Parallel Corpus
The latest version par-skcs-4.0 was released in May 2016. The database contains 418.5 million tokens (209.2 million in the Slovak half, 209.3 million in the Czech half).
The corpus consists of the following parts: the subcorpus of fiction and the free subcorpus. Apart from fiction, the subcorpus of fiction (19 million tokens) also contains other texts e.g. popular science, literature of fact, etc. User can query the corpus using the NoSketch Engine or through simple WWW interface. Subcorpus par-skcs-fic-4.0 contains texts identical to par-skcs-fic-3.0.
The free subcorpus consists of EU legal texts and reports, computational and other manuals translated from the third (English) language. The texts can be downloaded here.
Slovak-Czech Parallel Corpus is a database of texts that are translations of each other, Slovak texts are translated into Czech or vice versa. Texts are automatically sentence aligned. Slovak texts are automatically morphologically annotated by taggers Morče and MorphoDiTa which have been trained and tuned on the tagset developed by the Slovak National Corpus. The Czech texts are annotated by the tagger Morče which has been trained and tuned on the tagset developed by the Czech National Corpus.
There are several ways how to query the corpus:
through a dictionary interface. This does not contain the whole corpus, just automatically selected translation equivalents.
through a simple WWW interface. Enter the query term (Slovak/Czech word or a regular expression) into the input field Search. In the selection box corpus, choose the desired source for a particular term (par-skcs-*-sk for Slovak texts and par-skcs-*-cs for Czech texts). By clicking on the leftmost column, a short bibliography will be displayed.
