# Stanza Parser with CoNLL-U Viewer
|
| 14 |
+
|
| 15 |
+
A comprehensive linguistic analysis tool powered by Stanford's Stanza library that provides sentence parsing with multiple output formats.
|
| 16 |
+
|
| 17 |
+
## Features
|
| 18 |
+
|
| 19 |
+
- **Multi-language Support**: Parse text in English, Spanish, French, German, Chinese, Russian, and Arabic
|
| 20 |
+
- **CoNLL-U Output**: Get standard linguistic annotation format output
|
| 21 |
+
- **Interactive Data Table**: Browse parsed tokens with all linguistic features
|
| 22 |
+
- **Dependency Visualization**: Text-based visualization of dependency relationships
|
| 23 |
+
- **Copy-friendly Output**: Easy to copy results for use in other tools
|
| 24 |
+
|
| 25 |
+
## What is CoNLL-U?
|
| 26 |
+
|
| 27 |
+
CoNLL-U is a standard format for representing linguistic annotations that includes:
|
| 28 |
+
|
| 29 |
+
- **Tokenization**: Word and sentence boundaries
|
| 30 |
+
- **Part-of-Speech Tagging**: Universal and language-specific POS tags
|
| 31 |
+
- **Lemmatization**: Base forms of words
|
| 32 |
+
- **Morphological Features**: Grammatical attributes
|
| 33 |
+
- **Dependency Parsing**: Syntactic relationships between words
|
| 34 |
+
|
| 35 |
+
## How to Use
|
| 36 |
+
|
| 37 |
+
1. Enter your text in the input box
|
| 38 |
+
2. Select the appropriate language
|
| 39 |
+
3. Click "Parse Text" or press Enter
|
| 40 |
+
4. View results in three formats:
|
| 41 |
+
- Raw CoNLL-U format (copy-paste ready)
|
| 42 |
+
- Interactive data table
|
| 43 |
+
- Dependency structure visualization
|
| 44 |
+
|
| 45 |
+
## Example Output
|
| 46 |
+
|
| 47 |
+
For the sentence "The cat sits on the mat", you'll get:
|
| 48 |
+
|
| 49 |
+
- **CoNLL-U format**: Standard 10-column format with all linguistic features
|
| 50 |
+
- **Data table**: Interactive view of each token's properties
|
| 51 |
+
- **Dependencies**: "cat --nsubj--> sits", "mat --nmod--> sits", etc.
|
| 52 |
+
|
| 53 |
+
## Use Cases
|
| 54 |
+
|
| 55 |
+
- **Linguistic Research**: Analyze sentence structure and grammatical relationships
|
| 56 |
+
- **NLP Development**: Generate training data or test parsing models
|
| 57 |
+
- **Educational**: Learn about syntactic analysis and dependency grammar
|
| 58 |
+
- **Text Processing**: Prepare annotated data for downstream tasks
|
| 59 |
+
