### Dataset Summary
|
60 |
-
|
61 |
-
This dataset is a version of the [**20 Newsgroups**](https://scikit-learn.org/0.19/datasets/twenty_newsgroups.html#the-20-newsgroups-text-dataset) dataset fixed with the help of the [**Galileo ML Data Intelligence Platform**](https://www.rungalileo.io/). In a matter of minutes, Galileo enabled us to uncover and fix a multitude of errors within the original dataset. In the end, we present this improved dataset as a new standard for natural language experimentation and benchmarking using the Newsgroups dataset.
|
62 |
-
|
63 |
-
### Curation Rationale
|
64 |
-
|
65 |
-
This dataset was created to showcase the power of Galileo as a Data Intelligence Platform. Through Galileo, we identify critical error patterns within the original Newsgroups training dataset - garbage data that do not properly fit any newsgroup label category. Moreover, we observe that these errors permeate throughout the test dataset.
|
66 |
-
|
67 |
-
As a result of our analysis, we propose the addition of a new class to properly categorize and fix the labeling of garbage data samples: a "None" class. Galileo further enables us to quickly make these data sample changes within the training set (changing garbage data labels to None) and helps guide human re-annotation of the test set.
|
68 |
-
|
69 |
-
#### Total Dataset Errors Fixed: 1163 *(6.5% of the dataset)*

## Dataset Structure
|
80 |
-
|
81 |
-
### Data Instances
|
82 |
-
|
83 |
-
For each data sample, there is the text of the newsgroup post, the corresponding newsgroup forum where the message was posted (label), and a data sample id.
|
84 |
-
|
85 |
-
An example from the dataset looks as follows:
|
86 |
-
```
|
87 |
-
{'id': 1,
|
88 |
-
'text': 'I have win 3.0 and downloaded several icons and BMP\'s but I can\'t figure out\nhow to change the "wallpaper" or use the icons. Any help would be appreciated.\n\n\nThanx,\n\n-Brando'
|
89 |
-
'label': comp.os.ms-windows.misc}
|
90 |
-
```
|
91 |
-
|
92 |
-
|
93 |
-
### Data Fields
|
94 |
-
|
95 |
-
- id: the unique numerical id associated with a data sample
|
96 |
-
- text: a string containing the text of the newsgroups message
|
97 |
-
- label: a string indicating the newsgroup forum where the sample was posted
|
98 |
-
|
99 |
-
### Data Splits
|
100 |
-
|
101 |
-
The data is split into a training and test split. To reduce bias and test generalizability across time, data samples are split between train and test depending upon whether their message was posted before or after a specific date, respectively.
|
102 |
-
|
103 |
-
### Data Classes
|
104 |
-
|
105 |
-
The fixed data is organized into 20 newsgroup topics + a catch all "None" class. Some of the newsgroups are very closely related to each other (e.g. comp.sys.ibm.pc.hardware / comp.sys.mac.hardware), while others are highly unrelated (e.g misc.forsale / soc.religion.christian). Here is a list of the 21 classes, partitioned according to subject matter:
|
106 |
-
|
107 |
-
| comp.graphics<br>comp.os.ms-windows.misc<br>comp.sys.ibm.pc.hardware<br>comp.sys.mac.hardware<br>comp.windows.x | rec.autos<br>rec.motorcycles<br>rec.sport.baseball<br>rec.sport.hockey | sci.crypt<br><sci.electronics<br>sci.med<br>sci.space |
|
