Weight semiring

LauriLyly - 21 Nov 2012 - 00:34

So far I find thrax a very neat piece of software but I have two questions...

Can I somehow use probability semiring as weights, because it seems Thrax only allows specifying log and tropical semirings? How about the other ones... Or should I somehow postprocess the generated far file?

Another question: I tried to use "fstdraw" on a far file, but got: ERROR: FstHeader::Read: Bad FST header: example.far

Is this a version mismatch?

Sorry, obviously my bad as it's a far and not an fst file stick out tongue Still not too familiar. But the weight question still applies wink

Sorry, I missed the earlier comment -- for some reason I didn't get email about it.

Unfortunately the restriction to Log and Tropical is due to a similar restriction in the fst library: the real semiring does not come predefined. The best suggestion would be to use Tropical and then just do the obvious e^-cost conversion.
