| # Summary | |
| The Lithuanian dependency treebank ALKSNIS v3.0 (Vytautas Magnus University). | |
| # Introduction | |
| This is a conversion of the ALKSNIS treebank to Universal Dependencies. | |
| The original treebank was annotated in a style derived from the Prague Dependency Treebank of Czech. | |
| The original treebank is available at | |
| [https://github.com/Semantika2/Alksnis-v.3.0](https://github.com/Semantika2/Alksnis-v.3.0). | |
| ALKSNIS v2.1 is published in the CLARIN LT repository at | |
| [http://hdl.handle.net/20.500.11821/10](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](http://clarin-lt.lt/?page_id=86).) | |
| ALKSNIS v3 consists of 3,643 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. 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. | |
| The morphology tag set Jablonskis is used since ALKSNIS v2.2 and in the XPOS | |
| column of the UD conversion. This is a change from ALKSNIS 2 where a version | |
| of the MULTEXT-East tag set was used. | |
| <!--A version of the MULTEXT-East | |
| (http://nl.ijs.si/ME/V4/msd/html/index.html) | |
| tag set is used in ALKSNIS v2 and in the XPOS column of the UD conversion.--> | |
| Syntactically annotated sentences | |
| are corrected according to guidelines that were created by scientists of | |
| VMU CCL, following rules of Prague Dependency Treebank. All the sentences are | |
| being manually checked and corrected by a group of linguists. | |
| # Acknowledgements | |
| From v2.1 to v3.0 the treebank was developed within the project "Semantika2" | |
| (Nr. 02.3.1-CPVA-V-527-01-0002). The project was funded by European Structural Funds. | |
