Lexical Resources and Tools for Tagging Polish Texts Within Gramlex

Abstract

In this paper we present some of the main results obtained within the European project COPERNICUS 621 "GRAMLEX" aiming at development of basic resources, tools and methods useful in language engineering. Results presented here were obtained by the Polish team of the GRAMLEX project using Polish data but are easily portable to all Indo-European languages. They are of special interest for highly inflectional languages (e.g. for all Slavonic languages). The high portability of results follows from the proposed, very general format of morphological description (GRAMCODE) and from the general character and great simplicity of algorithms referring to this format. In the paper we briefly present the GRAMODE format, as well as the fundamental dictionary based tool for morphological lemmatization and tagging of texts (LEXAN).

Towards Lexicon-Grammar Verbnets Through Lexical Ontologies

“…The dictionary resource obtained was used in the implementation of valency structures in PolNet v3. For this reason, PolNet v3 may be considered the first mature version of Lexicon-Grammar Verbnet (Vetulani, Z. & Vetulani, G., 2016).…”

Development of real size IT systems with language competence as a challenge for a Less-Resourced Language: a methodological proposal for Indo-Aryan languages

“…Incremental development of PolNet started with general and frequently used vocabulary. 16 We decided to select the most widely used words found in a reference corpus of Polish language (Vetulani et al, 1997), with an important exception made for methodological reasons: even though we intended PolNet to be a resource of general interest, we assumed its possibly early validation in the real-size applications for which having a domain-specific terminology represented in the system was crucial. By 2008, the initial PolNet version based on noun synsets related by hyponymy/hyperonymy relations was already large enough to serve as a core lexical ontology for real-size applications.…”

“…10. These tools and applications were: (i) a lemmatizer/tagger (LEXAN) (Vetulani et al, 1997(Vetulani et al, , 1998b, (ii) a generator of inflected forms for simple and compound lexemes (Vetulani et al, 1998b), (iii) a syntactic concordance generator (SCON) (Vetulani et al, 1998b), (iv) a tool for the extraction of compound terms and terminology from texts (EXTRACT) (Vetulani et al, 1998b), (v) an application for the structure analysis of dictionary entries (VERBAN) (Vetulani et al, 1998b), (vi) an application for acquisition of the lexicon from dictionary definitions (NOUNAN) (Vetulani et al, 1998b), and (vii) an application for interactive analysis of dictionary definitions (NOUNDAN) (Vetulani et al, 1998b). 11.…”
