Ollie sometimes inserts "be" over conjunction edge

[schmmd]

Hi

Having grabbed the latest Ollie JAR which I believe is v1.0.2 I’ve noticed something odd having run a few sentences through it and wondered if you could take a look and confirm whether it’s a bug. I had used an older version before (1.0.0) and ran this sentence through it again to check that version and I don’t see the same oddity.

Here is a simple form of the sentence structure that demonstrates the problem:
The dog has died due to shock and is being buried at home tomorrow.

With Ollie 1.0.0 we get:
0.793: (The dog; has died due to; shock)
0.698: (The dog; is being buried at; home)

But with 1.0.2 we get:
0.673: (The dog; has died is due to; shock)
0.554: (The dog; has is being buried at; home)

Other than the scores changing, its simply the inclusion of the multiple VBZ nodes across the two relations that doesn’t look right. Could you confirm this is unexpected behavior, I couldn’t think of a reason why you might want this to be the case. Sorry if this has already been fixed I haven’t had time to grab the very latest source and build it to test against.

Thanks

This is an issue from the conjunction-expansion code rewritten a while back.
