QAWiki:Guide/Questions

Guidelines for creating questions

Here are some tips for writing questions and linking them with other related questions.

Question labels and aliases

The main label for the question should be quite specific, while aliases can provide more informal ways to ask a question. The main label should thus reflect as closely as possible the meaning of the query (and vice-versa). A good example might be "Which countries have a female head of state?". While it might be more natural to ask about female presidents, female prime ministers, queens, etc., these are questions with different results (and should be treated as distinct questions). Another example might be "What movies were directed by Mira Nair?", which is better than "What did Mira Nair direct?" for the main label as it specifies that we seek movies, not TV series, video games, etc., as reflected in the query.

Ambiguous questions

Ambiguous questions like "What is the largest country in Africa?" are welcome, but they should be tagged as instance of the class ambiguous question and should not provide a query. Ideally, each ambiguous question should link to one or more candidate questions that the user might mean, such as "What is the largest country in Africa by population?" and "What is the largest country in Africa by area?". Systems using QAWiki can then suggest to the user these more specific questions in a "Did you mean ..." style interaction. Other types of ambiguity might arise due to entities mentioned in the question being ambiguous. To avoid a proliferation of disambiguation, it can be assumed that the most "obvious" entity in the context of the question applies in general, much like in Wikpedia, where Michael Jackson points directly to the famous singer; however, there may be cases where there is no one "obvious" entity being referred to, in which case an ambiguous question can be generated.

Analogous questions

The goal of QAWiki is to create a diverse collection of questions and queries. In general, we do not recommend generating many instance of analogous questions, such as "What is the capital of X?" for many values of X. A single instance, such as "What is the capital of Ireland?" is often sufficient, where other examples can be generated automatically. However, there may be cases where it is useful to have several manually generated instances of an analogous query (that vary only in their particular selection of entities); this may be due to having different types of entities (e.g., the capital of a state vs. country), to capture different subtleties (e.g., the gender of the entity and how it affects the expression of the question), etc. If one wishes to add many specific instances of a question (whose query varies only in its subject/object entities in a one-to-one manner), we recommend using the analogous question property to link these instances; for example, see "When did Stan Lee die?" linked with "When did Ian Curtis die?". This should not be used where the underlying intent of the question is different; for example "What is the capital of IBM?" may refer to something different (working capital of a business) and would thus not be analogous to the capital of a country, etc. (the query would require a different property).

Contingent questions
