Re: [help-GIFT] struggling with running GIFT...

[Niles Johnson]

Hi Neville,

I haven't re-checked all the attachments you sent, but as far as I 
remember, the output has included complaints about the collection ID 
number each time . . .

In your 'gift-config.mrml', note the line beginning with:

<collection collection-id="c-38-27-1-27-6-108-0-208-0" collection-name="imgs"..

I have a collection with collection-name="Full-Image-Collection" and 
collection-id="c-01"; in my 'gift-config.mrml', and the algorithms 
reference this collection ID.  This is probably why, in the output you 
sent, you see the error about collection c-01 not being described in your 
config file.

So I'd suggest you update your 'gift-config.mrml' in two ways:

First, Henning explained to me that the "Classical IDF" algorithm does 
not perform as well as the "Separate Normalisation" algorithm, and his 
'gift-config.mrml' does not include either the "PERL link" or the 
"Classical IDF" algorithms.  Following his recommendation, I 
deleted both of these from my 'gift-config.mrml' and am having 
better performance from the GIFT--I'd encourage you to do the same :)

To do this, just delete everything between <algorithm ... > and 
</algorithm>. Be warned that XML doesn't parse nested comments like you 
might expect, so even though I commented out the "PERL link" algorithm by 
adding '<!--' at the beginning, and '-->' at the end, this won't work for 
the "Classical IDF" algorithm, since there are comments within the 
algorithm block.


Second, check the line beginning with:

<algorithm algorithm-id="adefault" algorithm-type="adefault" 
algorithm-name="Separate Normalisation" collection-id=

to be sure that the collection-id matches the one listed in your 
collection reference.  The GIFT generates a collection ID number every 
time it indexes a new collection, but as far as I can tell, you don't have 
to use the number it generates.

I can't remember if you need to update the collection ID in any of the 
other GIFT files, but maybe you can just try it with these changes and see 
how it works?  Hopefully the new output can help us identify any other 
problems . . .

best,
Niles

p.s.  I think it's close to working for you, so hang in there!  If you 
still have trouble, you might also check to see that your GIFT client is 
referencing the correct collection ID's, while we're at it.
