== Project description ==

This project is continuation of the former project (3 T11C 018 29) on the construction of plWordNet 1.0 -- the first publicly available wordnet for Polish.
The main goal of this project is to extend and improve Distributional Semantics methods and pattern-based methods developed in the former project and to build a complex, semi-automatic system supporting linguists working on plWordNet construction. 

The second goal is to extend plWordNet 1.0 to the size of 70000-80000 lexical units (pairs: lemma, sense number) and 45000-55000 synsets.

The main objective of both projects was to construct a Polish !WordNet as economically as possible. 

Polish !WordNet is a network of lexical-semantic relations, an electronic thesaurus with a structure modelled on that of the Princeton !WordNet and those constructed in the !EuroWordNet project. Polish !WordNet describes the meaning of a lexical unit of one or more words by placing this unit in a network of links which represent such relations as synonymy, hypernyny, meronymy etc. 

To reduce the cost of the project, Polish !WordNet was built semi-automatically. Lexical relations were automatically recognized in large corpora of Polish, e.g., [[IPI PAN Corpus]]) and suggested to linguists/lexicographers via a graphical interface.
