 # Math StackExchange Curated (Parquet, CC BY-SA 4.0)
 
-This dataset is a curated collection of Math StackExchange (MSE) Q&A pairs packaged in **Parquet** format for efficient loading and training.  
-Each example contains a problem statement (`title`, `question_body`), a corresponding community answer (`answer_body`), a tag string (`tags`), and an indicator of whether the answer is the accepted solution (`accepted`).

 ## Schema
 
-| field          | dtype  | description |
-|----------------|--------|-------------|
-| `title`        | string | Thread title (short problem description). |
-| `question_body`| string | Full post body of the question (often includes LaTeX/MathJax). |
-| `answer_body`  | string | Answer text (the primary answer included in this dataset). |
-| `tags`         | string | Pipe-delimited MSE tags, e.g. `\|number-theory\|elementary-number-theory\|`. |
-| `accepted`     | int64  | `1` if the included answer is the accepted solution, otherwise `0`. |
-
-> **Note on `tags`:** tags come as a single string with leading/trailing pipes. See the snippet below to normalize them into a Python list.
+Field | Type | Description
+----- | ----- | -----------
+title | string | The title of the original Math StackExchange thread.
+question_body | string | Full body of the question, often including LaTeX/MathJax.
+answer_body | string | The answer chosen for this dataset (may or may not be accepted).
+tags | string | Pipe-delimited set of tags, e.g. `|number-theory|elementary-number-theory|`.
+accepted | int64 | `1` if the included answer was the accepted solution, else `0`.

+## Loading
+
+### Using Hugging Face datasets
+
+```
+
+from datasets import load_dataset
+ds = load_dataset("<username>/<dataset_name>")
+print(ds["train"][0])
+
+```
+
+### Loading Parquet directly
+
+```
+
+from datasets import Dataset
+train = Dataset.from_parquet("math_stackexchange_train.parquet")
+val   = Dataset.from_parquet("math_stackexchange_val.parquet")
+test  = Dataset.from_parquet("math_stackexchange_test.parquet")
+
+```
+
+---
+
+## Tag normalization
+
+```
+
+def split_tags(s):
+if not s:
+return []
+return [t for t in s.strip("|").split("|") if t]
+
+example = ds["train"][0]
+tags = split_tags(example["tags"])
+print(tags)
