Semi-formal, so I would think a shirt and trousers, probably with a tie, are a definite yes. If you have space for a suit then maybe that is a better pick.
Can I suggest people avoid terms like "semi-formal"? It's so ambiguous as to be meaningless. Black-tie is (well, was) sometimes described as "informal evening wear" (with white-tie being formal), so "semi-formal" could even describe something more formal than black-tie. You're using it to mean something even less formal than a lounge suit. That's a very wide range!
Unless you are setting a dress code that is clearly an unambiguously defined (like "black-tie" or "morning wear"), then don't give it a name. Just describe what you mean. I would describe the dress code the organisers seem to be trying to go for as:
"Smart trousers and shirt, jacket and tie optional, for men. Similar, or a smart dress for women. Equivalent national dress is also welcome."
