The Lithuanian dependency treebank ALKSNIS v3.0 (Vytautas Magnus university). From v.2.1 to v.3.0 was developed during the project "Semantika2" (Nr. 02.3.1-CPVA-V-527-01-0002)

This is a new corrected and enhanced version of the ALKSNIS Lithuanian treebank. It is annotated in a style derived from the Prague Dependency Treebank of Czech. The previous ALKSNIS v2.1 consists of 2,355 syntactically annotated sentences. Each node of a tree corresponds to a word, a punctuation mark or other text element (symbol, digit etc.) within a sentence. ALKSNIS v.2.1 is published in CLARIN LT repository at http://hdl.handle.net/20.500.11821/10. (Some users experience DNS errors when trying to access the repository; configuring the client machine to use 8.8.8.8 as the DNS server may help. See also http://clarin-lt.lt/?page_id=86.) A version of the MULTEXT-East (http://nl.ijs.si/ME/V4/msd/html/index.html) tag set is used in ALKSNIS v2.1. The following information is presented for each node: 1) a used form; 2) a lemma; 3) a morphology tag, and 4) a syntactic function (subject, object, etc.). Dependencies are shown by links between words. ALKSNIS v3.0 from v2.1 was developed during the Vytautas Magnus University project “Semantika2” (Nr. 02.3.1-CPVA-V-527-01-0002). It consists of 3,643 syntactically annotated sentences.
