The on-line version of Grammatical Dictionary of Polish

The Online Version of Grammatical Dictionary of Polish Marcin Woliński, Witold Kieraś Institute of Computer Science, Polish Academy of Sciences Jana Kazimierza 5, 01-248 Warszawa, Poland wolinski@ipipan.waw.pl Abstract We present the new online edition of a dictionary of Polish inflection – the Grammatical Dictionary of Polish (http://sgjp.pl). The dictionary is interesting for several reasons: it is comprehensive (over 330,000 lexemes corresponding to almost 4,300,000 different textual words; 1116 handcrafted inflectional patterns), the inflection is presented in an explicit manner in the form of carefully designed tables, the user interface facilitates advanced queries by several features (lemmas, forms, applicable grammatical categories, types of inflection). Moreover, the data of the dictionary is used in morphological analysers, including our product Morfeusz (http://sgjp. pl/morfeusz). From the very beginning, the dictionary was meant to be convenient for human reader as well as to be ready for use in NLP applications. In the paper we briefly discuss both aspects of the resource. Keywords: inflectional dictionary, Polish, morphological analysis 1. About the Dictionary The idea of the dictionary was conceived by its primary au- thor Zygmunt Saloni some 35 years ago under the influence of a grammatical dictionary of Russian (Zalizniak, 1977). The project evolved slowly, first by analysing grammatical information in the largest dictionary of Polish printed on pa- per in 11 volumes (Doroszewski, 1958–1969). Important milestones were the new systematisation of Polish declen- sion (Gruszczyński, 1989), the schematic reverse index of Polish word forms (Tokarski, 1993), the dictionary of Pol- ish conjugation (Saloni, 2001). The mentioned works were published as paper books, but they were based on data pre- pared using databases. In particular, the verbal database be- came the seed for description of other parts of speech. The first and second edition of the Grammatical Dictionary of Polish (Słownik gramatyczny języka polskiego, SGJP) ap- peared in the form of a computer program (Saloni et al., 2007b; Saloni et al., 2012). At this stage, the team in- cluded Zygmunt Saloni, Marcin Woliński, Robert Wołosz, Włodzimierz Gruszczyński, and Danuta Skowrońska as the authors, with many formal and informal co-workers (listed at the project’s web page). For the third edition we de- cided to change the form to a web application available http://sgjp.pl (Saloni et al., 2015). 2. The Scope of SGJP SGJP covers the whole list of entries of the mentioned dictionary of Polish (Doroszewski, 1958–1969), including a whole range of archaic, obsolete, dialectal and otherwise stylistically marked words, since its extensive lexical basis goes back to even last decades of 18th century. On the other hand, numerous new words were added, including a signif- icant number of proper names as well as some modern vo- cabulary collected during various linguistic investigations. As a result, the original lexical basis of Doroszewski’s dic- tionary, estimated at ca. 130,000 lexemes, was significantly extended. The number of lexemes of various grammatical classes is illustrated in Table 1. The primary scope of interest in SGJP is inflection. Un- like in most other dictionaries, inflectional paradigms are presented explicitly in the …
