Description:
All this goes back to Allen's interval-based semantics defined in 1983 in his paper
"Maintaining Knowledge about temporal relationships". In it the 13 relationships
are defined. In fact, we have the "equals" relation, plus 6 further
relationships and their inverses (e.g., "before" is the inverse relationship of
"after"). I wrote down how to formally interpret the visual representation for
all 13 relationships given by Allen on page 4 (see the box at the upper right corner; the
pictoral example illustrates best the situation) of the paper, i.e. I expressed them in
the format you suggested using the start and end time of the events. Here we go (of
course, for all events E must hold: E.startTS <= E.endTS).
A equals B: (A.startTS == B.startTS) && (A.endTS == B.endTS)
A before B: (A.endTS < B.startTS)
A after B: (A.startTS > B.endTS)
A meets B: (A.endTS == B.startTS)
A met-by B: (A.startTS == B.endTS)
A overlaps B: (A.startTS < B.startTS) && (A.endTS < B.endTS)
A overlapped-by B: (A.startTS > B.startTS) && (A.endTS > B.endTS)
A during B: (A.startTS > B.startTS) && (A.endTS < B.endTS)
A contains B: (A.startTS < B.startTS) && (A.endTS > B.endTS)
A starts B: (A.startTS == B.startTS) && (A.endTS < B.endTS)
A started-by B: (A.startTS == B.startTS) && (A.endTS > B.endTS)
