+# Sentence Parse Trees
+
+This dataset contains high-quality English sentences and their corresponding parse trees. It is derived from the [agentlans/high-quality-english-sentences](https://huggingface.co/datasets/agentlans/high-quality-english-sentences) dataset, 
+with parse trees generated using [spaCy](https://spacy.io/) `en_core_web_sm` package. Abnormally long or short parses have been removed.
+
+## Dataset Description
+
+- **Size:** 1&thinsp;502&thinsp;479 entries
+- **Source:** [agentlans/high-quality-english-sentences](https://huggingface.co/datasets/agentlans/high-quality-english-sentences)
+- **Parsing Tool:** spaCy
+
+## Data Format
+
+Each entry in the dataset is a JSON object with two fields:
+
+1. `text`: The original sentence
+2. `parse`: The parse tree in Lisp-style S-expression format
+   - Each list contains: syntactic dependency relation, the word, and the parse tree of its descendants
+   - Words are enclosed in double quotes and escaped where necessary
+
+### Example Entry
+
+```json
+{
+  "text": "At present, this mechanism has become one of the three major pillars underpinning the development of China-UK relations.",
+  "parse": "(ROOT \"become\" (prep \"At\" (pobj \"present\")) (punct \",\") (nsubj \"mechanism\" (det \"this\")) (aux \"has\") (attr \"one\" (prep \"of\" (pobj \"pillars\" (det \"the\") (nummod \"three\") (amod \"major\") [...]"
+}
+```
+
+## Usage
+
+This dataset can be used for various natural language processing tasks, including:
+
+- Syntactic parsing research
+- Grammar analysis
+- Language model training
+- Linguistic studies
