===== Positional annotation and tagging =====

Compared to the Czech corpora NKJP_1M has in addition a positional attribute which is specific for Polish, so called **flexeme**.  It is a category based on part of speeches that are further divided into more specific lexeme classes. Thus, there are for example within nouns (//subst//) differed depreciative nouns (//depr//), beside of common adjectives (//adj//) there are ad-adjectival adjectives (//adja//, e.g. //__biało__-czerwony//, //__sportowo__-rekreacyjny//), post-prepositional adjectives (//adjp//, e.g. //po __polsku__//, //od __dawna__//), predicative adjectives (//adjc//, e.g. //jestem __pewien__//, //był __wesół__ i __zdrów__//), particulary is delicate the distinction of verbal categories (more than 10 different flexemes). 

Moreover, the Polish tagset differs from the Czech one; its detailed description (including the list of all flexemes) is available [[http://nkjp.pl/poliqarp/help/ense2.html|here]].

In addtion, two positional attributes were added to the original corpus: ''lc'' and ''lemma_lc'', which allow to search regardless of case-sensitive in the corpus.
