12.7.1 Know and Know Simple Queries

The intent of a Know query is to find information on a topic. Users want to Know more about something.

Know Simple queries are a special type of Know query. Know Simple queries seek a very specific answer, like a fact, diagram, etc. This answer has to be correct and complete, and can be displayed in a relatively small amount of space: the size of a mobile phone screen. As a rule of thumb, if most people would agree on a correct answer, and it would fit in 1-2 sentences or a short list of items, the query can be called a Know Simple query.

Know Simple queries may be questions such as [how tall is barack obama]. Frequently, Know Simple queries do not have question words. For example, [barack obama height] has the same user intent as [how tall is barack obama], but is not in a question format.

Most queries are not Know Simple queries, such as:

● Broad, complex, and/or in-depth informational queries that do not have a short answer
● Ambiguous or unclear informational queries
● Informational queries on controversial topics
● Informational queries with no definitive “right answer”
● Queries where different users may want different types of information, or different sources of information

Here are some examples where the Know Simple query asks for a simple fact, which can be answered correctly and completely in a small amount of space, and the Know query answer is more complex.

Raters must think about mobile users when deciding if queries are Know Simple. Use your judgment here.

Important Rating Example: The query [weather] may seem like a broad information query, but most mobile users likely have a fairly simple informational need: to find the current or upcoming temperature, and the chance of local weather events, such as rain or snow. Therefore, we will consider queries like [weather], [weather today], [weather tomorrow], [weather this week] to be Know Simple queries for mobile phone users.
