ZALIZNIAK’s grammatical dictionary : 96 000 entriescomplete dictionary, in inverted alphabetical order, with all grammatical annotation

To obtain, to reach :Достигать нсв нп 1a$3 (доcтигнуть//доcтичь) имеется страдDostigat’ ipf nt 1a$3 (dostignut’/dostich’) has a passive form

The problem of accent markers was delayed

Encountered problems Classification complete but some tags are absent ( V, N…)Classification based on accent markersA lot Unformal unclassified added annotations

Zalizniak’s dictionary was resorting, its classification was modified, simplified and completed for computer use

Russian grammars for NoojRussian grammars for Nooj

All these grammars need improvement:All these grammars need improvement:

They are very sensitive to syntactic order :-fail to regognize structures if unusual ( expressive or non standard) order of word in Russian sentences.

There are no grammars (yet) :-to disambiguate adverbs / adjectives -to disambiguate adjectives / nouns-to disambiguate conjunctions / interjections

2828

To get reliable ressources To get reliable ressources for the Russian languagefor the Russian language : :

• Data bank of verified and annotated texts

design and implement:

• Efficient syntactic grammars

• Develop semantic tagging

• Unified or harmonized tags for (slavic, roman, german etc..) languages to allow further multilingual treatment
