Editing Main Page (section)

== 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.

# Create a [[Special:NewItem|new item]].
# Add the question in the language(s) you prefer as the label of the new item.
# Optionally add other ways to ask the same question as aliases.
# Add the claim that the new item is an [[Property:P1|instance of]] [[Item:Q1|question]].

If you're looking for some tips, [[QAWiki:Guide/Questions|see the following guide]].

=== Translate questions ===

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

# Use the [http://query.qawiki.org/#%23%20finds%20questions%20without%20versions%20in%20French%20%28change%20the%20%22fr%22%20code%20to%20find%20questions%20not%20in%20other%20languages%29%0ASELECT%20%3Fq%20%3FqLabel%20WHERE%20%7B%20%3Fq%20wdt%3AP1%20wd%3AQ1%20.%20MINUS%20%7B%20%3Fq%20rdfs%3Alabel%20%3Fqlab%20.%20FILTER%28lang%28%3FqlabEn%29%3D%22fr%22%29%20%7D%20SERVICE%20wikibase%3Alabel%20%7B%20bd%3AserviceParam%20wikibase%3Alanguage%20%22%5BAUTO_LANGUAGE%5D%2Cen%22.%20%7D%20%7D 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).
# Set your language in the top right where it indicates English.
# 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.

# Use the [http://query.qawiki.org/#%23%20finds%20questions%20with%20few%20entity%20mentions%20given%20for%20a%20language%20%28in%20this%20case%20English%2C%20but%20you%20can%20change%20the%20code%20%22en%22%20within%20the%20FILTER%20expression%0ASELECT%20%3Fq%20%3FqLabel%20%28COUNT%28DISTINCT%20%3Fo2%29%20AS%20%3FentityCount%29%20WHERE%20%7B%20%3Fq%20wdt%3AP1%20wd%3AQ1%20.%20SERVICE%20wikibase%3Alabel%20%7B%20bd%3AserviceParam%20wikibase%3Alanguage%20%22%5BAUTO_LANGUAGE%5D%2Cen%22.%20%7D%20OPTIONAL%20%7B%20%3Fq%20wdt%3AP47%2a%2Fp%3AP38%20%3Fo1%20.%20%3Fo1%20pq%3AP17%20%3Fo2%20.%20%3Fo1%20ps%3AP38%20%3Fo3%20.%20FILTER%28lang%28%3Fo3%29%20%3D%20%22fr%22%29%7D%20%7D%20GROUP%20BY%20%3Fq%20%3FqLabel%20ORDER%20BY%20%3FentityCount following query] to find questions ordered by the number of entity mentions annotated for a language (the example is French, but you can change the two letter "fr" code to any language).
# Visit the question(s) you like. 
# Add new values for the [[Property:P38|mention]] property in the language of your choice. These should be substrings of a question or alias in the same language.
# Add one or more qualifier values for the [[Property:P17|Wikidata item ID]] property indicating the item on Wikidata that the mention(s) refer(s) to in the specific context of the question.

If you're looking for tips, [[QAWiki:Guide/Mentions|see the following guide]].

=== Add mentions for properties === 

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

# Use the [http://query.qawiki.org/#%23%20finds%20questions%20with%20few%20property%20mentions%20given%20for%20a%20language%20%28in%20this%20case%20English%2C%20but%20you%20can%20change%20the%20code%20%22en%22%20within%20the%20FILTER%20expression%29%0ASELECT%20%3Fq%20%3FqLabel%20%28COUNT%28DISTINCT%20%3Fo2%29%20AS%20%3FentityCount%29%20WHERE%20%7B%20%3Fq%20wdt%3AP1%20wd%3AQ1%20.%20SERVICE%20wikibase%3Alabel%20%7B%20bd%3AserviceParam%20wikibase%3Alanguage%20%22%5BAUTO_LANGUAGE%5D%2Cen%22.%20%7D%20OPTIONAL%20%7B%20%3Fq%20wdt%3AP47%2a%2Fp%3AP38%20%3Fo1%20.%20%3Fo1%20%28pq%3AP18%7Cpq%3AP45%7Cpq%3AP48%7Cpq%3AP49%7Cpq%3AP50%7Cpq%3AP51%7Cpq%3AP52%7Cpq%3AP55%7Cpq%3AP56%7Cpq%3AP58%7Cpq%3AP59%29%20%3Fo2%20.%20%3Fo1%20ps%3AP38%20%3Fo3%20.%20FILTER%28lang%28%3Fo3%29%20%3D%20%22fr%22%29%7D%20%7D%20GROUP%20BY%20%3Fq%20%3FqLabel%20ORDER%20BY%20%3FentityCount following query] to find questions ordered by the number of property mentions annotated for a language (the example is French, but you can change the two letter "fr" code to any language).
# Visit the question(s) you like. 
# Add new values for the [[Property:P38|mention]] property in the language of your choice. These should be substrings of a question or alias in the same language.
# Add one or more qualifier values for the [[Property:P18|Wikidata property 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 who are familiar with query languages like SPARQL you can also provide queries to answer questions on the [https://query.wikidata.org/ Wikidata Query Service].

# Use the [http://query.qawiki.org/#%23%20finds%20questions%20without%20a%20corresponding%20query%0ASELECT%20%3Fq%20%3FqLabel%20WHERE%20%7B%20%3Fq%20wdt%3AP1%20wd%3AQ1%20.%20SERVICE%20wikibase%3Alabel%20%7B%20bd%3AserviceParam%20wikibase%3Alanguage%20%22%5BAUTO_LANGUAGE%5D%2Cen%22.%20%7D%20MINUS%20%7B%20%3Fq%20wdt%3AP11%20%3Fo%20.%20%7D%20%7D following query] to find questions without a corresponding query.
# Visit the question(s) you like.
# Add the query to solve the question via the property [[Property:P11|query]].
# Add the qualifier [[Property:P13|dataset]] to indicate [[Item:Q12|Wikidata]] and the qualifier [[Property:P12|query language]] to indicate [[Item:Q13|SPARQL]].

=== Other ways to help out ===

* You can also build tools and systems using QAWiki and [[Main_Page#Systems_using_QAWiki|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 the query or [https://www.wikidata.org/wiki/Wikidata:Main_Page Wikidata] to improve those answers.
* You can help to curate QAWiki. See this [[QAWiki:Curation/Quality_Control_Queries|list of quality-control queries]] that help to detect potential issues to correct.
