If you are not familiar with query languages like SPARQL you can:

Welcome to QAWiki: a repository of questions and queries that anyone can contribute to!

QAWiki collects questions in different languages, and queries over knowledge bases like Wikidata that can answer them.

Questions are typically factual so that they are answerable by knowledge bases. As some examples:

Here you can query for all the questions (and queries) collected thus far by QAWiki.

Systems using QAWiki

How can I contribute?

There are many ways in which you can contribute to QAWiki (whether or not you are familiar with SPARQL, Wikidata, etc.)

Suggest new questions

QAWiki welcomes new questions relating to your interests! Other editors can then hopefully suggest a query, add mentions, translations, etc.

  1. Create a new item.
  2. Add the question in the language(s) you prefer as the label of the new item.
  3. Optionally add other ways to ask the same question as aliases.
  4. Add the claim that the new item is an instance of question.

Translate questions

QAWiki aims to be a multilingual resource, so translations of questions and other elements into the languages you speak is very welcome!

  1. Use the following query to find questions without a translation (the example is for French, but you can change the two letter "fr" code to any language).
  2. Visit the questions you like and translate the question to your language.

Add mentions for entities

Adding entity mentions is much appreciated, and will help systems using QAWiki to be more precise.

  1. Use the following query to find questions ordered by the number of entity mentions annotated for a language (the example is English, but you can change the two letter "en" code to any language).
  2. Visit the question(s) you like.
  3. Add new values for the mention property in the language of your choice. These should be substrings of a question or alias in the same language.
  4. Add one or more qualifier values for the Wikidata item ID property indicating the item on Wikidata that the mention(s) refer(s) to in the specific context of the question.

Add mentions for properties

Again, adding property mentions is very welcome, and will help systems using QAWiki to be more precise.

  1. Use the following query to find questions ordered by the number of property mentions annotated for a language (the example is English, but you can change the two letter "en" code to any language).
  2. Visit the question(s) you like.
  3. Add new values for the mention property in the language of your choice. These should be substrings of a question or alias in the same language.
  4. Add one or more qualifier values for the Wikidata property ID property indicating the item on Wikidata that the mention(s) refer(s) to in the specific context of the question.

Adding entity mentions is much appreciated, and will help systems using QAWiki to be more precise.

  1. Use the following query to find questions ordered by the number of entity mentions annotated for a language (the example is English, but you can change the two letter "en" code to any language).
  2. Visit the question(s) you like.
  3. Add new values for the mention property in the language of your choice. These should be substrings of a question or alias in the same language.
  4. Add one or more qualifier values for the Wikidata item ID property indicating the item on Wikidata that the mention(s) refer(s) to in the specific context of the question.

Add queries to answer questions

If you are familiar with query languages like SPARQL you can also add queries that answer questions!

  1. Use the following query to find questions without a corresponding query.
  2. Visit the question(s) you like.
  3. Add the query to solve the question via the property query.
  4. Add the qualifier dataset to indicate Wikidata and the qualifier query language to indicate SPARQL.

Other ways to help out

  • You can also build tools and systems using QAWiki and add them to the list. (You can also consider adding a link back to QAWiki for users to add questions that your system struggled with.)
  • Try out some of the queries, and if you see some dubious or missing answers, edit Wikidata to improve those answers.
  • You can help to curate QAWiki.
