A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
Use tags that describe what your question is about, not what it merely relates to. For example almost every question on this site is eventually related to research, but only questions about performing research should be tagged research.
Use tags describing circumstances only if those circumstances are essential to your question. For example, if you have a question about citations that came up during writing a thesis but might as well have arisen during writing a paper, do not tag it with thesis.
► complete the sentence: my question is about...
► use tags that describe things or concepts that are essential, not incidental to your question
► favor using existing popular tags
► read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
► combine multiple words into single-words with hyphens (e.g. graduate-admissions), up to a maximum of 35 characters
