# Language Graph Parser
Parse sentences into linguistic structure graphs using deep learning.
## Model
This Space uses the [rudaoshi/lingua](https://huggingface.co/rudaoshi/lingua) model, which is a BERT-based parser with biaffine attention for word-lingua graph prediction.
## Features
- **Sentence Parsing**: Input any English sentence to parse it into a linguistic structure graph
- **Graph Visualization**: Visualize the parsed graph with nodes and edges
- **Constrained Decoding**: Use pattern-based constrained decoding for better graph structure (enabled by default)
## Usage
1. Enter a sentence in the text box
2. Optionally toggle "Use Constrained Decoding" (recommended)
3. Click "Parse Sentence" to generate the graph visualization
## Example Sentences
- "The cat sat on the mat."
- "John loves Mary."
- "I want to go to the store."
## Graph Structure
The parser generates graphs that represent:
- Predicate-argument relations (pred.arg.1, pred.arg.2, etc.)
- Modification relations (@modification, etc.)
- Discourse markers
- And more linguistic structures
## Technical Details
- **Model Architecture**: BERT + Biaffine Attention
- **Decoding**: Greedy pattern-based constrained decoding
- **Output Format**: Linguistic Graph Structure |
