What is Słowosieć?
Słowosieć is the Polish wordnet — a modern dictionary of the Polish language and a database describing vocabulary for the needs of natural language processing (NLP).
Individual word senses are linked by relations that describe connections and dependencies between them. Thanks to a dense network of relations, words can in a sense “define themselves”, providing rich information about meanings to both dictionary users and computer programs.
Słowosieć serves as both a lexical-semantic database and a model of conceptual resources of language. As a digital publication, it can be continuously developed, corrected, and expanded with new relation types, glosses, and annotations.

Data for 2024. Słowosieć is currently the world’s largest wordnet, larger than its predecessor — Princeton WordNet — and the largest dictionary of Polish.
See detailed statisticsSłowosieć can be used in programs that rely on automatic language processing — from text analysis to dialogue systems.
As a modern dictionary, it helps anyone seeking guidance in vocabulary and every language user.
Enables quantitative research on language material, multilingual analyses, and psycholinguistic experiments.
Słowosieć is a key resource in computational language processing and artificial intelligence research. It is used, among others, in machine translation (e.g. Google Translate) and in projects integrating resources across many languages.
Part of the data is shared via the Open Multilingual WordNet platform, which brings together dozens of wordnets for languages around the world, linked by mapping to Princeton WordNet. This makes Słowosieć an important component of the global infrastructure of language resources.
The Polish wordnet is built through the joint effort of lexicographers and computer scientists from the Language Technology Group at Wrocław University of Technology. Users can access Słowosieć via the website and Wordnet Loom, and can also download source files and use web services.
