# Japanese Wikipedia Human Retrieval dataset |
|
|
|
This is a Japanese question answereing dataset with retrieval on Wikipedia articles |
|
by trained human workers. |
|
|
|
## About the dataset |
|
|
|
Each entry represents a single QA session: |
|
given a question sentence, the responsible worker tried to search for the appropriate |
|
information from Wikipedia using the search box and/or inner hyperlinks, and constructed |
|
the answer paragraphs according to the search results. |
|
The whole process of each retrieval is recorded manually by the same worker. |
|
|
|
All sessions are processed from 2023-12-04 to 2023-12-25 with access to Japanese Wikipedia |
|
(http://ja.wikipedia.org/). |
|
|
|
The dataset consists of following data: |
|
|
|
* A question sentence |
|
* The final answer paragraph (whole sentence, and chunks with citations) |
|
* List of references with either extracted paragraph or summarization from a Wikipedia |
|
article |
|
|
|
## Target situation and limitation |
|
|
|
We designed this dataset to ensure that the answers reflect only exact information written in the cited references, |
|
and does not reflect any external information and/or implicit knowledges. |
|
This design is useful to measure/investigate QA tasks with accurate retrieval from the given data source. |
|
Please keep in mind that the dataset is not designed to provide a QA with correct information. |
|
|
|
We requested the workers strictly to answer the questions based on only explicit citation from Wikipedia. |
|
That means, the workers should write answers that may be different from their implicit knowledge, |
|
and should leave the answer empty if they couldn't find any information from Wikipedia |
|
even if they know something to answer the questions. |
|
|
|
# Dataset chunks |
|
|
|
As well as successful sessions with answer paragraphs, we also recorded failed sessions: |
|
the worker failed to construct the answer from the search results. |
|
In this case we recorded at least the retrieval process despite lack of the answer. |
|
|
|
We release this version of the dataset with the following dataset chunks: |
|
|
|
* "answered" chunk (838 examples): question, answer, and retrieval process |
|
* "not_answered" chunk (433 examples): question and retrieval process (no answer) |
|
|
|
## Data structure |
|
|
|
Each entry has the following schema: |
|
|
|
```js |
|
{ |
|
"id": number, // Entry ID |
|
"question": string, // Question sentence |
|
|
|
// Answer section |
|
// Absense of this field means that the worker failed to answer the question. |
|
"answer": { |
|
"text": string, // Answer paragraph |
|
|
|
// Answer sentences |
|
// These sentences are written by the workers based on the cited references. |
|
// The above answer paragraph is generated by joining all texts in this list. |
|
"sentences": [ |
|
{ |
|
"text": string, // Answer sentence |
|
"citations": number[], // List of reference IDs for citation |
|
} |
|
], |
|
}, |
|
|
|
// Reference list |
|
"references": [ |
|
{ |
|
// Either "search" or "link" field exists. |
|
|
|
// Information for direct search (search box on Wikipedia) |
|
"search": { |
|
"keywords": string[], // List of words input into the search box |
|
}, |
|
|
|
// Information for hyperlinks |
|
"link": { |
|
"referrer": number, // The reference ID at which the worker clicked the hyperlink |
|
} |
|
|
|
// Either "page" or "not_found" field exists. |
|
|
|
// Extracted content |
|
"page": { |
|
"title": string, // Title of the Wikipedia article |
|
"url": string, // URL of the Wikipedia article |
|
|
|
// Either "quote" or "summary" field exists. |
|
// Absense of both field means that the page doesn't contain appropriate data. |
|
|
|
// Information for direct quotation |
|
// There could be multiple "page" fields with "quote" subfield if multiple |
|
// sentences are extracted from distant positions in the same page. |
|
"quote": { |
|
"text": string, // Consecutive texts extracted from the article |
|
}, |
|
|
|
// Information for summarization |
|
"summary": { |
|
"text": string, // Summary text about the page written by the worker. |
|
"method": string, // Description about how the worker wrote the summary. |
|
} |
|
} |
|
|
|
// Search result (not found) |
|
"not_found": { |
