== Project description ==

The main objective of the project 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.
