+## Dataset Description
+
+- **Homepage:** [stackexchange](https://archive.org/details/stackexchange)
+- **Repository:** [flax-sentence-embeddings](https://github.com/nreimers/flax-sentence-embeddings)
+
+### Dataset Summary
+
+We automatically extracted question and answer (Q&A) pairs from [Stack Exchange](https://stackexchange.com/) network. Stack Exchange gather many Q&A communities across 50 online plateform, including the well known Stack Overflow and other technical sites. 100 millon developpers consult Stack Exchange every month. The dataset is a parallel corpus with each question mapped to the top rated answer. The dataset is split given communities which cover a variety of domains from 3d printing, economics, raspberry pi or emacs. An exhaustive list of all communities is available [here](https://stackexchange.com/sites).
+
+### Languages
+
+Stack Exchange mainly consist of english language (en).
+
+## Dataset Structure
+
+### Data Instances
+
+Each data samples is presented as follow:
+
+```
+{'title_body': "Is there a Stack Exchange icon available? StackAuth /sites route provides all the site's icons except for the one of the Stack Exchange master site.\nCould you please provide it in some way (a static SVG would be good)?",
+ 'upvoted_answer': 'Here it is!\n\nDead link: SVG version here\nNote: the same restrictions on this trademarked icon that apply here, also apply to the icon above.',
+ 'downvoted_answer': 'No, the /sites route is not the right place for that.\n\n/sites enumerates all websites that expose API end-points. StackExchange.com does not expose such an endpoint, so it does not (and will not) appear in the results.'}
+```
+
+This particular exampe corresponds to the [following page](https://stackapps.com/questions/1508/is-there-a-stack-exchange-icon-available)
+
+### Data Fields
+
+The fields present in the dataset contain the following informations:
+
+- `title_body`: This is the concatenation of the title and body from the question
+- `upvoted_answer`: This is the body from the most upvoted answer
+
+### Data Splits

+## Dataset Creation
+
+### Curation Rationale
+
+We primary designed this dataset for sentence embeddings training. Indeed sentence embeddings may be trained using a contrastive learning setup for which the model is trained to associate each sentence with its corresponding pair out of multiple proposition. Such models require many examples to be efficient and thus the dataset creation may be tedious. Community networks such as Stack Exchange allow us to build many examples semi-automatically.
+
+### Source Data
+
+The source data are dumps from [Stack Exchange](https://archive.org/details/stackexchange)
+
+#### Initial Data Collection and Normalization
+
+We collected the data from the math community. 
+
+We filtered out questions which title or body length is bellow 20 characters and questions for which body length is above 4096 characters.
+
+#### Who are the source language producers?
+
+Questions and answers are written by the community developpers of Stack Exchange.
