16:01:26 [ericP]hey, you's guys all have college degrees and that sort of thing, how can i, given a set of interesting nodes in a graph, trim off all the bits of the graph that aren't interesting?
16:02:50 [danbri]do you find specific edges interesting too?
16:03:00 [danbri]http://horicky.blogspot.com/2010/02/nosql-graphdb.html and nearby has a pile of graph theory btw
16:05:51 [ericP]nope, just nodes
16:05:53 [ericP]for instance, given node pairs: a,b c,a b,d c,e e,a e,f
16:05:53 [ericP]and the set of interesting nodes: {a,f}
16:05:53 [ericP]i want to get back only the node pairs which connect a and f
16:05:53 [ericP]viable connections being c,a - c,e - e,f | e,a - e,f
16:05:55 [ericP](which excludes the pairs a,b and b,d)
16:13:41 [danbri]so you want the skinniest web that can be thrown around your interesting nodes?
16:13:51 [danbri]seems like running shortest pathfinder a few times?
16:13:55 [danbri]check out that blog post

16:49:55 [ericP]danbri, tx. i'm poking through it

16:51:11 [wcattey]K. has asked me to create some new stuff in a directory called: dig.csail.mit.edu/2010/DHS-Fusion/FL/rules/
16:51:28 [danbri]ericp, see http://web.archive.org/web/20070421015159/http://rdfweb.org/people/damian/2002/02/foafnation/ for pretty pictures
16:51:50 [wcattey]But I don't know if that means creating a top level svn repo or if I can do it with svn myself.
16:52:01 [danbri]heh 'Last modified: Tue Feb 19 18:41:27 GMT 2002'
16:53:11 [wcattey]I think there is, as yet, no 2010 subdirectory of dig.csail.mit.edu
16:55:05 [ericP]you're already 11% of the way through 2010. see if you can hold out on publishing until 2011
16:55:18 [ericP]that way you can solve tbe problem only once instead of twice
16:55:50 [fuming]fuming has quit (Quit: fuming)
16:56:21 [wcattey]Actually, having a subdirectory per year is, in my opinion a ghastly conflation of semantics and opaque location identifier that should simply never be made.
16:56:43 [wcattey]But I was hired to use the conventions in place, not to change them.
16:57:27 [wcattey]How do I create an FL subdir? I've heretofore only cloned subtrees of that svn universe.
16:57:41 [wcattey](I also need to create an MD directory.)
16:57:53 [Pipian]Should just be able to stick a file in the folder, do an "svn add" of the folder, and the commit the changes.
16:58:46 [wcattey]I don't actually have a working copy of top-level dig.csail.mit.edu to do such a thing to.
16:59:48 [wcattey]I guess I should more accurately have stated, "I've been working on subtrees, cloning only subsets of the whole tree."
16:59:49 [Pipian]You shouldn't need the top-level, I don't think. As long as you can commit, it'll commit in the proper tree underneath dig.csail.mit.edu
17:00:06 [Pipian]But then if you don't have the whole tree, then yeah, you'd have to clone the whole tree to add the subdirectory at the top level.
17:00:47 [wcattey]Is there yet even a 2010 directory there now?
17:01:33 [Pipian]Yeah, there's a /2010 directory
17:02:48 [wcattey](svn ls of anything gives me back 403 Forbidden)
17:03:50 [Pipian]You should be able to pull it at least.
17:05:53 [wcattey]I'm attempting: svn co https://dig.csail.mit.edu/2010/DHS-fusion/
17:06:04 [wcattey]That returns forbidden.
17:06:27 [wcattey]changing https to http returns :OPTIONS ... OK, but doesn't seem to check anything out.
17:06:43 [Pipian]Believe it's a capital F maybe?
17:06:49 [wcattey]is there a DHS-[Ff]usion directory under 2010 yet?
17:07:08 [Pipian]Survey says...
17:07:10 [wcattey]It was lower case in the 2009 subdirectory.
17:07:31 [Pipian]No, from the looks of it.
17:09:10 [wcattey]svn co http://dig.csail.mit.edu/2010 returns, "repository permanently moved to dig.csail.mit.edu/2010/"
17:09:33 [wcattey]Adding the trailing slash gives the same error.
17:09:46 [wcattey]So it's been permanently relocated to where I'm accessing. Great.
17:10:00 [wcattey]and using https gives 403 forbidden
17:15:03 [wcattey]Could you create a DHS-fusion directory on the server?
17:15:12 [oshani]wcattey, try svn co https://svn.csail.mit.edu/dig/2010
17:15:26 [oshani]and then create the sub directory, add and commit as Pipian suggested
17:16:58 [oshani]also, don't ever create any thing on the server. Always do create the files and folders on your local machine and then commit
17:17:41 [wcattey]Ah! Right! I need to use svn.csail...

17:18:38 [wcattey]Oshani: inasmuch as the subdir of 2009 is DHS-fusion with lower case 'f', I think I should create the directory with that same name, and NOT change it to an upper case 'F'. What do you think?
17:19:05 [oshani]wcattey, I also think consistency is good
17:21:17 [wcattey]Ok. I've created the DHS-fusion directory there.
17:24:39 [wcattey]Thanks very much for the help.

18:22:26 [lkagal]wcattey, I was wondering why you were creating another dir with the same name ?
18:48:03 [mhausenblas]mhausenblas has quit (Quit: mhausenblas)
20:26:37 [wcattey]lkagal: Yes. I discussed it with K. We're going to be consistent with the wrong name originally set: DHS-fusion with lower case 'f'.

21:48:03 [lkagal]oshani ?
21:48:19 [oshani]lkagal, what's up?
21:51:37 [lkagal]I believe you've worked with Jena. Do you know if it has any probabilistic reasoning capabilities ?
21:53:34 [oshani]I haven't seen anything that mentions that in their API lkagal. But I am not sure. May be you should ask on #swig ?
21:53:45 [lkagal]Thanks
21:56:39 [oshani]lkagal, this paper: http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.94.8010&rep=rep1&type=pdf claims that they have used Jena in their impl to provide probabilistic/uncertainty reasoning. So, I assume Jena does not support it.
22:00:30 [lkagal]Thanks. The paper appears to be from ISWC 2005, Jena could have added it by now.
22:01:26 [oshani]yeah, I guess
