+## <a name="_9kx40vcgmdtk"></a>**Overview**
+Rada\_Trees is a comprehensive syntactically annotated corpus of Ukrainian parliament (Verkhovna Rada) transcripts spanning over three decades (1990–2024). This corpus contains approximately 88 million tokens, making it one of the most extensive annotated parliamentary corpora for the Ukrainian language.  Paragraphs in Russian and those where Russian words predominate were removed using the CleanText tool ([nlp_uk/doc/README_other.md at master · brown-uk/nlp_uk](https://github.com/brown-uk/nlp_uk/blob/master/doc/README_other.md)).
+## <a name="_4kxnt4m3ixfj"></a>**Key features**
+- **Size**: ~88 million tokens
+- **Period**: 1990–2024 (nine convocations)
+- **Language**: Ukrainian. 
+- **Source**: Official transcripts from plenary sessions downloaded from the Verkhovna Rada open data portal (<https://www.rada.gov.ua/)>
+- **Formats**: Available in three annotation formats:
+  - Plain text (original transcripts)
+  - UD annotation (https://universaldependencies.org/)
+  - nlp\_uk annotation based on VESUM morphological dictionary (https://github.com/brown-uk/nlp\_uk)
+## <a name="_x4wdlml3hf41"></a>**Annotation details**
+The corpus includes comprehensive linguistic annotation.
+
+For data annotated with UD:
+
+- **Tokenization and sentence segmentation**
+- **Lemmatization**
+- **Universal POS tags (UPOS)** - part-of-speech tagging 
+- **Morphological features (FEATS)** - detailed grammatical information
+- **Dependency relations (HEAD, DEPREL)** - syntactic structure
+- **Format**: CoNLL-U (compatible with Universal Dependencies tools and parsers)
+
+For data annotated with nlp\_uk:
+
+- **Tokenization and sentence segmentation**
+- **Lemmatization**
+- **Morphological tags** containing information about pos and morphological features, as well as stylistic annotation (*bad*, *arch*, *rare*, *vulg*, etc.), according to the nlp\_uk standard.
