5 th Workshop on Intelligent and Knowledge oriented Technologies

The article presents current state of affairs in several projects conducted by the Slovak National Corpus department of the L’. Štúr Institute of Linguistics, Slovak Academy of Sciences. We describe the Slovak National Corpus, Corpus of Spoken Slovak, tools used for linguistics analysis and an ongoing effort to create Slovak WordNet. 1 Slovak National Corpus The Slovak National Corpus is a huge, representative corpus of modern written Slovak (since the 1953 orthography reform). Currently, the whole corpus contains over 700 million tokens. There are several specialised subcorpora (fiction, professional texts, journalistic texts, original Slovak fiction, balanced subcorpus, texts written until 1989). The corpus is automatically lemmatised and morphologically annotated and is indexed using the Manatee software [Ryc00]. To query the corpus, there are two possibilities – first, the users can use multiplatform (Tcl/Tk) Bonito client to access the Manatee server, using its own protocol. This approach provides the users with complete access to all the advanced querying, sorting and statistical features of the server, however requires installation of a specialized software. The other possibility is to use web based access, where only basic features are present. In both cases, the search interface provides CQL compatible query syntax. However, in the last few years the ability of an average user to install arbitrary software (and use anything that is not web-based) declined considerably, and new corpus users often face an insurmountable obstacle in downloading, unpacking and running the Bonito client. Because of this, we are considering transfer of the corpus to Manatee-2, which provides complete web-based interface as a replacement of the Tcl/Tk client. A separate corpus (although part of the whole Slovak National Corpus project) is a manually morphologically annotated corpus, whose main purpose is to be a source of train data for Slovak language tagger (and, to a lesser extent, for morphology annotation
