-### Dataset Summary
-
-The description below was taken from the paper "Multi-task Pairwise Neural Ranking for Hashtag Segmentation"
-by Maddela et al..
-
-"STAN large, our new expert curated dataset, which includes all 12,594 unique English hashtags and their 
-associated tweets from the same Stanford dataset.
-
-STAN small is the most commonly used dataset in previous work. However, after reexamination, we found annotation 
-errors in 6.8% of the hashtags in this dataset, which is significant given that the error rate of the state-of-the art 
-models is only around 10%. Most of the errors were related to named entities. For example, #lionhead, 
-which refers to the “Lionhead” video game company, was labeled as “lion head”.
-
-We therefore constructed the STAN large dataset of 12,594 hashtags with additional quality control for human annotations."

-## Dataset Structure
-
-### Data Instances
-
-```
-{
-    "index": 15,
-    "hashtag": "PokemonPlatinum",
-    "segmentation": "Pokemon Platinum",
-    "alternatives": {
-        "segmentation": [
-            "Pokemon platinum"
-        ]
-    }
-}
-```
-
-### Data Fields
-
-- `index`: a numerical index.
-- `hashtag`: the original hashtag.
-- `segmentation`: the gold segmentation for the hashtag.
-- `alternatives`: other segmentations that are also accepted as a gold segmentation.
-
-Although `segmentation` has exactly the same characters as `hashtag` except for the spaces, the segmentations inside `alternatives` may have characters corrected to uppercase.
-
-## Dataset Creation
-
-- All hashtag segmentation and identifier splitting datasets on this profile have the same basic fields: `hashtag` and `segmentation` or `identifier` and `segmentation`.
-
-- The only difference between `hashtag` and `segmentation` or between `identifier` and `segmentation` are the whitespace characters. Spell checking, expanding abbreviations or correcting characters to uppercase go into other fields.
-
-- There is always whitespace between an alphanumeric character and a sequence of any special characters ( such as `_` , `:`, `~` ). 
-
-- If there are any annotations for named entity recognition and other token classification tasks, they are given in a `spans` field.
