## Dataset Description |
|
|
|
- **Repository:** [WikiAnc repository](https://github.com/cyanic-selkie/wikianc) |
|
|
|
### Dataset Summary |
|
|
|
The WikiAnc HR datasets is an automatically generated dataset from Wikipedia (hr) and Wikidata dumps (March 1, 2023). |
|
|
|
The code for generating the dataset can be found [here](https://github.com/cyanic-selkie/wikianc). |
|
|
|
### Supported Tasks |
|
|
|
- `wikificiation`: The dataset can be used to train a model for Wikification. |
|
|
|
### Languages |
|
|
|
The text in the dataset is in Croatian. The associated BCP-47 code is `hr`. |
|
|
|
You can find the English version [here](https://huggingface.co/datasets/cyanic-selkie/wikianc-en). |

## Dataset Structure |
|
|
|
### Data Instances |
|
|
|
A typical data point represents a paragraph in a Wikipedia article. |
|
|
|
The `paragraph_text` field contains the original text in an NFC normalized, UTF-8 encoded string. |
|
|
|
The `paragraph_anchors` field contains a list of anchors, each represented by a struct with the inclusive starting UTF-8 code point `start` field, exclusive ending UTF-8 code point `end` field, a nullable `qid` field, a nullable `pageid` field, and an NFC normalized, UTF-8 encoded `title` (Wikipedia) field. |
|
|
|
Additionally, each paragraph has `article_title`, `article_pageid`, and (nullable) `article_qid` fields referring to the article the paragraph came from. |
|
|
|
There is also a nullable, NFC normalized, UTF-8 encoded `section_heading` field, and an integer `section_level` field referring to the heading (if it exists) of the article section, and the level in the section hierarchy that the paragraph came from. |
|
|
|
The `qid` fields refers to Wikidata's QID identifiers, while the `pageid` and `title` fields refer to Wikipedia's pageID and title identifiers (there is a one-to-one mapping between pageIDs and titles). |
|
|
|
**NOTE:** An anchor will always have a `title`, but that doesn't mean it has to have a `pageid`. This is because Wikipedia allows defining anchors to nonexistent articles. |
|
|
|
An example from the WikiAnc HR test set looks as follows: |
|
|
|
``` |

### Data Fields |
|
|
|
- `uuid`: a UTF-8 encoded string representing a v4 UUID that uniquely identifies the example |
|
- `article_title`: an NFC normalized, UTF-8 encoded Wikipedia title of the article; spaces are replaced with underscores |
|
- `article_pageid`: an integer representing the Wikipedia pageID of the article |
|
- `article_qid`: an integer representing the Wikidata QID this article refers to; it can be null if the entity didn't exist in Wikidata at the time of the creation of the original dataset |
|
- `section_heading`: a nullable, NFC normalized, UTF-8 encoded string representing the section heading |
|
- `section_level`: an integer representing the level of the section in the section hierarchy |
|
- `paragraph_text`: an NFC normalized, UTF-8 encoded string representing the paragraph |
|
- `paragraph_anchors`: a list of structs representing anchors, each anchor has: |
|
- `start`: an integer representing the inclusive starting UTF-8 code point of the anchors |
|
- `end`: an integer representing the exclusive ending UTF-8 code point of the anchor |
|
- `qid`: a nullable integer representing the Wikidata QID this anchor refers to; it can be null if the entity didn't exist in Wikidata at the time of the creation of the original dataset |
|
- `pageid`: a nullable integer representing the Wikipedia pageID of the anchor; it can be null if the article didn't exist in Wikipedia at the time of the creation of the original dataset |
|
- `title`: an NFC normalized, UTF-8 encoded string representing the Wikipedia title of the anchor; spaces are replaced with underscores; can refer to a nonexistent Wikipedia article |
|
|
|
### Data Splits |
|
|
|
The data is split into training, validation and test sets; paragraphs belonging to the same article aren't necessarily in the same split. The final split sizes are as follows: |
|
|
|
| | Train | Validation | Test | |
|
| :----- | :------: | :-----: | :----: | |
|
| WikiAnc HR - articles | 192,653 | 116,375 | 116,638 | |
|
| WikiAnc HR - paragraphs | 2,346,651 | 292,590 | 293,557 | |
|
| WikiAnc HR - anchors | 8,368,928 | 1,039,851 | 1,044,828 | |
|
| WikiAnc HR - anchors with QIDs | 7,160,367 | 891,959 | 896,414 | |
|
| WikiAnc HR - anchors with pageIDs | 7,179,116 | 894,313 | 898,692 | |
|
|
|
**NOTE:** The number of articles in the table above refers to the number of articles that have at least one paragraph belonging to the article appear in the split. |
