+# Dataset Card for Wikipedia Comments
+
+<!-- START-SHORT DESCRIPTION -->
+Text from the comments sections of the Danish Wikipedia.
+<!-- END-SHORT DESCRIPTION -->

+You can read more about the wikipedia on their [about](https://da.wikipedia.org/wiki/Hj%C3%A6lp:Om) page.

+## Dataset Description
+
+
+<!-- START-DESC-STATS -->
+- **Language**: dan, dansk, Danish
+- **Domains**: Encyclopedic
+- **Number of samples**: 
+- **Number of tokens (Llama 3)**: 
+- **Average document length (characters)**: 
+<!-- END-DESC-STATS -->
+
+
+
+## Dataset Structure
+An example from the dataset looks as follows.
+
+
+<!-- START-SAMPLE -->
+```py
+```
+
+### Data Fields
+
+An entry in the dataset consists of the following fields:
+
+- `id` (`str`): An unique identifier for each document.
+- `text`(`str`): The content of the document.
+- `source` (`str`): The source of the document (see [Source Data](#source-data)).
+- `added` (`str`): An date for when the document was added to this collection.
+- `created` (`str`): An date range for when the document was originally created.
+- `token_count` (`int`): The number of tokens in the sample computed using the Llama 8B tokenizer
+<!-- END-SAMPLE -->

+
+## Additional Information
+
+This dataset is collected using an adapted version of the [WikiExtractor](https://github.com/attardi/wikiextractor). Rob van der Goot created a fork that allows for extracting additional text from Wiki's. The fork can be found here: [WikiExtractor](https://github.com/robvanderg/wikiextractor.git). 
+
+After inspection of the different outputs, there are multiple categories of files, which can most easily be distinguished through the title field. Below, I list the different categories, their size (number of pages), and what they seem to contain after a manual inspection. 
+
+```
+  71472 Kategori: category overview pages
+  19992 Wikipedia: Comments, but also daily articles
+   2379 Portal: Also monthly articles, and some lists/calendars 
+   1360 MediaWiki: About files, contains almost no natural language
+    726 Modul: technical stuff, contains almost no (Danish) text
+    171 Hjælp: help pages; info and comments
+```
+
+In the current version of the dataset, we used the titles starting with `Wikipedia:` , and remove the daily articles by leaving out titles starting with "Wikipedia:Dagens".
