HASK gives users instant access to lists of word combinations found in reference corpora of English and Polish. The resource may be used to find potential collocates of any noun, verb, adjective or adverb in a number of predefined patterns. In addition to detailed statistics, it is also possible to browse through the underlying concordances, visualise and download phraseological profiles for a given entry. Apart from its descriptive role in theoretical phraseology research, the HASK dictionary is a valuable tool for linguists, teachers and students of English and Polish, and lexicographers. Two basic tools are available for collocation databases:

1) collocation browser, i.e. an advanced tool for the analysis and visualisation of phraseological connectivity of selected words on the basis of NKJP and BNC corpora; the browser enables to sort collocation search results by relevance, download the results in the form of spreadsheets and check the source concordances which were used to generate individual headwords;

2) colosaurus, i.e. an innovative tool for comparing the textual co-occurence of certain words; colosarus makes it possible to quickly investigate which typical collocates are shared by a number of words of interest (e.g. a given set of nouns, adjectives, verbs or adverbs) using graph-based visualisations; colosaurus allows for studying the extent of synonymy in the textual use of co-occuring words; the generated graphs can be downloaded and re-modeled by the users.
