I'm working on a research paper, I need a word or phrase which is related to users' location, time and event. If there's isn't exact word or phrase then any best fit would also work out.
I think context may be used to suggest what you are referring to:
the set of circumstances or facts that surround a particular event, situation, etc.
the conditions and circumstances that are relevant to an event, fact, etc
I would suggest situation for this.
From The Free Dictionary's collected definitions for situation, we find the following shades of meaning:
state of affairs; combination of circumstances
manner of being situated; location or position with reference to environment.
the combination of circumstances at a given time
It is easy to infer from this that situation goes beyond mere physical placement to include other conceptual notions of placement. Certainly time and extended environment are amply covered.
