Yes, this is a mess:

B ∅
Bm7b5
Bm7♭5
Bm7-5
Bmin7(b5)
B minor seven flat five
B minor 7 flat 5
B minor 7th flat 5
B half diminished
B half-diminished chord
B half-diminished 7th
Si half-diminished chord
Si minor seven flat five
And some more combinations...

The solution is, obviously, a keyboard for the chord builder grin
